You may often think that a fast heartbeat is normal or even a sign of good things. However, for tens of millions of people with cardiovascular disease, arrhythmias or palpitations are a sign of a very serious health condition.

 Atrial fibrillation, also known as AFib or AF, is a shaking or irregular heartbeat that can lead to heart failure, blood clots and even stroke. It is the most common serious heart rhythm abnormality.

With each heartbeat, an electrical signal spans from the top of the heart to the bottom, which causes the heart to contract and pump blood. Normally, your heart contracts and relaxes to a regular beat. AFib occurs when a fast and disorganized electrical signal causes the heart’s two upper chambers (atria) to contract very rapidly and irregularly (also known as fibrillation). This causes blood to pool in the atria instead of being pumped completely into the ventricles, the two lower chambers of the heart. As a result, the upper and lower chambers are out of sync and the heart’s efficiency is lost.

With AFib, the rate of impulses through the atria can vary from 300 to 600 beats per minute. A normal resting heart rate does not exceed 100 beats per minute. It is important to make an appointment with a cardiologist if you suspect the type of arrhythmia.

‎AFibCheck – Atrial fibrillation, screening can also be searched for “AFibCheck” from various app stores and downloaded.

As many as 30% of AFib cases are not diagnosed until life-threatening complications develop, meaning there is an urgent need for more efficient screening methods that can be applied at scale.

As an app for early screening of atrial fibrillation, AFibCheck does not require other equipment, just a mobile phone. Based on PPG technology, it can identify human heart rhythm and atrial fibrillation detection. This method is very convenient and practical, which supports the sharing of atrial fibrillation data to doctors, etc.

1. Heart rate predicts the length of life

Some animals’ lives are short-lived, while others last longer than Nanshan. Behind such a disparate life cycle, people found that their hearts beat about 800 million times. Among animals, the longevity tortoise has a long life of more than 500 years, and its heart beats at least 10 times per minute; while a little mouse has a fast heartbeat, as high as 1,200 times per minute, and only lives for more than a year before dying. According to research, the life cycle of all animals follows such a law: the faster the heart rate, the shorter the lifespan. Humans are no exception, but civilized life makes its heartbeat limit several times that of 800 million. So, biologists say that the secret to longevity is to make the heartbeat as calmly as possible.

Infants and young children: Generally speaking, the normal heartbeat range during this period is 100 to 140 beats per minute. During the crying period of infants and young children, it may even reach 180 beats per minute. During quiet sleep, the heart rate will drop and may be reduced to 70 beats per minute.

Adult period: The heart development of adults has tended to be perfect. During this period, the normal heart rate of the human body is generally 75 beats per minute, which is normal in the range of 60 to 100 beats per minute. Obviously, the heart rate of adults is more than that of infants. Toddlers are a little slower.

Elderly age: In older age, the normal heart rate of the human body is about 70 beats per minute, which is slightly slower than that of adults, but the difference is not obvious. Many elderly people suffer from high blood pressure, heart disease and other diseases. When the heart beats too fast or too slow, it will be life-threatening.

In addition, in addition to age being the cause of different heart beat times, different states can also lead to differences in human heart beat times. Generally speaking, when the heartbeat of an adult exceeds 100 beats per minute, it becomes a tachycardia, which may be caused by intense exercise (up to 180 beats per minute), emotional tension, anxiety (up to 100 beats per minute), etc. It is also possible that the heartbeat is accelerated due to the onset of a pathological disease.

Heart rate can give timely feedback whether the human body is in a healthy state, whether it is slow or fast heart beat, it may be life-threatening.

2. Heart Rate Predicts Heart Attack Risk

As far as humans are concerned, although the heart rate of 60 to 90 beats per minute at rest is in the normal range, the optimal heart rate is about 70 beats per minute. A survey shows that people with a heart rate 12 beats per minute faster than normal are 27% more likely to die from cardiovascular disease than normal people. These prompts people not to ignore the speed of heart rate.

3. Heart rate predicts the prognosis of heart disease

Heart rate is fast or slow are an independent predictor of whether a heart patient will have life-threatening concerns within a year. Patients with consistently higher than normal heart rates, or with small differences between the fastest and slowest heart rates, have a fairly high chance of dying within a year. This suggests that therapy to stabilize and slow heart rate is directly related to patient survival.

4. Heart rate indicates whether the amount of exercise is appropriate

The amount of exercise is mainly measured by heart rate. For example, when aerobic exercise is effective and safe, the heart rate of a person is 170 minus the age, or it is controlled between 108 and 144.

5. Heart rate is a predictor of fatigue

Whether a person’s labor or exercise will cause fatigue due to excessive work depends on the heart rate the next morning. If the heart rate is more than 5 beats/minute faster than the previous day, it can be considered as excessive fatigue, and the amount of exercise or labor should be adjusted.

6. Heart rate prompts the effect of exercise and fitness

Whether the exercise is effective, the heart rate in the morning can also tell you. It is effective if the heart rate after a period of exercise is slower than that before the exercise by more than 5 beats/min. According to expert surveys, usually 3 months of exercise can make the heart rate start to drop 4 to 5 times per minute.

If you want to judge whether your body is healthy, you can know it by the heartbeat. Because the heart is a very important organ of the human body, maintaining a normal heartbeat can also maintain a healthy state. If the heartbeat can be maintained within the normal range, it can reflect the heart function is normal from the side.

If there is an abnormal heartbeat, you can actively take countermeasures, and you can usually maintain a normal heartbeat through some good living habits.

1. Exercise more

If you want to maintain a normal heartbeat, you should usually pay attention to the maintenance of the heart, and it is very effective to exercise more in the process of maintaining the heart. By exercising the body can improve the contractility of the heart muscle, so as to maintain the normal blood flow of the heart Circulation, and adequate blood supply to the heart naturally maintains a healthy state of the body.

Therefore, in the process of maintaining good health, you should pay attention to the development of good habits, and maintain good heart function by exercising, so that the heart will naturally maintain health and keep the heart rate normal.

2. Control your emotions

If you want to ensure changes in heart function, you should usually pay attention to emotional stability. Emotional fluctuations can also stimulate the body and increase the burden on the heart. Many people’s frequent anger or nervousness may stimulate the body and affect the body. After the burden on the heart increases, it may lead to heart disease. Therefore, in order to maintain good heart function, some good living habits should be adhered to, especially paying attention to the reasonable control of emotions is the key.

3. Stick to a healthy diet

Keeping the heart healthy requires a light diet, and some irritating foods need to be eaten less, such as high-fat foods, spicy foods, and alcohol-containing foods to avoid, so as to prevent food stimulation from increasing the burden on the heart or inducing heart disease.

It can be seen that if the heartbeat of an adult can be maintained at 70 to 80 beats per minute, it is in a normal range. If you want to keep the heart in a healthier state, you should pay attention to emotional control, exercise more, and eat a healthy diet. All are great for heart care.

Atrial fibrillation can happen to anyone, from children to adults. Because the likelihood of AFib increases with age, and because people are living longer today, medical researchers predict that the number of AFib cases will increase dramatically over the next few years. Although AFib clearly increases the risk of heart-related death and stroke, many patients do not fully appreciate the potentially serious consequences.

Atrial fibrillation, also known as AFib or AF, is a shaking or irregular heartbeat that can lead to heart failure, blood clots and even stroke. It is the most common serious heart rhythm abnormality.

As many as 30% of AFib cases are not diagnosed until life-threatening complications arise, meaning there is an urgent need for more efficient screening methods that can be applied at scale.

As an app for early screening of atrial fibrillation, AFibCheck does not require other equipment, just a mobile phone. Based on PPG technology, it can identify human heart rhythm and atrial fibrillation detection. This method is very convenient and practical, and supports the sharing of atrial fibrillation data to report to doctors.

Atrial fibrillation, also known as AFib or AF, is a shaking or irregular heartbeat that can lead to heart failure, blood clots and even stroke. It is the most common serious heart rhythm abnormality.

People with one or more of the following are generally at higher risk of developing AFib:

Advanced age: The number of adults with AFib increases significantly with age. Atrial fibrillation in children is rare, but it can and does happen.

High blood pressure: Long-term uncontrolled high blood pressure can increase your risk of developing AFib.

Underlying Heart Disease: Anyone with heart disease, including valve problems, hypertrophic cardiomyopathy, acute coronary syndrome, Wolf-Parkinson-White (WPW) syndrome, and a history of heart attack. Additionally, atrial fibrillation is the most common complication after cardiac surgery.

Drinking alcohol: Heavy drinking (five drinks in two hours for men and four drinks in two hours for women) may put you at a higher risk of developing AFib.

Family history: Having a family member with AFib increases your chances of being diagnosed.

Sleep apnea: Although sleep apnea has not been proven to cause AFib, research has shown a strong link between obstructive sleep apnea and AFib. Often, treating apnea improves AFib.

Athletes: AFib is common in athletes and can be triggered by a fast heart rate called supraventricular tachycardia (SVT).

Other chronic diseases: Others at risk are those with thyroid problems (especially hyperthyroidism), diabetes, asthma, and other chronic diseases.

You may often think that a fast heartbeat is normal or even a sign of good things. However, for tens of millions of people with cardiovascular disease, arrhythmias or palpitations are a sign of a very serious health condition.

Atrial fibrillation, also known as AFib or AF, is a shaking or irregular heartbeat that can lead to heart failure, blood clots and even stroke. It is the most common serious heart rhythm abnormality.

With each heartbeat, an electrical signal spans from the top of the heart to the bottom, which causes the heart to contract and pump blood. Normally, your heart contracts and relaxes to a regular beat. AFib occurs when a fast and disorganized electrical signal causes the heart’s two upper chambers (atria) to contract very rapidly and irregularly (also known as fibrillation). This causes blood to pool in the atria instead of being pumped completely into the ventricles, the two lower chambers of the heart. As a result, the upper and lower chambers are out of sync and the heart’s efficiency is lost.

With AFib, the rate of impulses through the atria can vary from 300 to 600 beats per minute. A normal resting heart rate does not exceed 100 beats per minute. It is important to make an appointment with a cardiologist if you suspect this type of arrhythmia.

Atrial fibrillation is the most common clinical arrhythmia with high morbidity and mortality, especially in the elderly.

The etiology of atrial fibrillation is still unknown, but many risk factors have been shown to be associated with the development of atrial fibrillation. Including: advanced age, high blood pressure, coronary heart disease, heart failure, hyperthyroidism, heart valve disease, fatigue, emotional agitation, mental stress, caffeine intake, hypoxia, electrolyte imbalance, serious infection and the effects of certain drugs, etc.

The most serious danger of atrial fibrillation is the formation of blood clots. This thrombus often cannot be firmly attached to the atrial cavity and is easy to fall off. When the thrombus breaks off into the ventricle, it can travel around the body with the blood pumped by the ventricle. At this time, once the thrombus stops in a small blood vessel and embolizes, the consequences are quite serious. For example, the well-known cerebral infarction is the result of a blood clot blocking the cerebral blood vessels. If the embolism is in the blood vessels of the lower extremities, it may cause swelling, numbness, and lameness of the patient’s unilateral lower extremity.

Therefore, for patients at high risk of thromboembolism, such as those who have experienced cerebral infarction, myocardial infarction, or valve replacement surgery, anticoagulation is the most important treatment regardless of whether rhythm control or ventricular rate control is used.

The danger of atrial fibrillation should be paid attention to, and the disease should not be ignored because of the severity of the symptoms. A free testing APP – AFibCheck, we can self-check at home anytime, anywhere, to achieve early detection and early treatment of atrial fibrillation and minimize damage.

Monitoring heart rate measurement methods are: blood oxygen method, photoplethysmography, ECG signal method, arterial pressure method, and signal analysis method.

1. Blood oxygen method

SpO2 is the kind that is clipped at the tip of the index finger. Generally speaking, a complete oximeter often has two types of light-emitting diodes, one with a wavelength of 660 nm, which is red light of visible light, and one with a wavelength of more than 900 nm, which is infrared light. The oxygen-carrying hemoglobin and the non-oxygen-carrying hemoglobin in the blood vessels have different absorption rates for the two types of light.

The advantage of the blood oxygen method is to provide two signals of heart rate and blood oxygen saturation. The disadvantage is that the transmitted light signal needs to be received at the other end, so this part of the human tissue must be thin enough, and the only suitable positions on the whole body are the fingertips and earlobes. The wrist is too thick, visible light cannot penetrate at all, and the range of use is relatively limited.

2. Photovoltaic volume method

This is tracking the reflection of visible light (green light) in human tissue. Usually there are two green LEDs that emit visible light to the wrist, and then a photo sensor in the middle senses the reflected light. The reflection of light by skin, bones, meat, and fat of the human body is a fixed value, while the reflection of light by capillaries and arterial veins is a fluctuating value because the pulse volume keeps getting bigger and smaller. The frequency of this fluctuation is the pulse, which is generally consistent with the heart rate.

3. ECG signal method

The sinoatrial node rhythmically controls systole and diastole to pump blood to the trunk. This control signal is an electrical signal (the human nerve signal is expressed as an electrical signal on the nerve), which will gradually spread to the body surface and can be measured by electrodes on the skin. The electrocardiograph uses this principle. This rhythm is the heart rate. In addition, the ECG signal can also provide a lot of reference information for doctors to diagnose.

4. Arterial blood pressure method

This is the oldest method, the pulse diagnosis of Chinese medicine. The pressure in the arteries, which can be felt through the skin on either side of the wrist or neck, fluctuates regularly. This signal can be turned into a heart rate by means of a pressure sensor.

5. Signal analysis method

The human face is captured by ordinary natural light for 5s to 30s through ordinary cameras, and weak periodic signals are extracted from the captured light under the blessing of artificial intelligence;

Through biological radar waves, the fluctuations and changes of the human body surface are monitored, and with the blessing of artificial intelligence, the signals are separated to obtain weak periodic signals;

Through the pressure film sensor, the pressure monitoring of the fluctuation of the human body surface is indirectly carried out. With the blessing of artificial intelligence, the signal is separated to obtain a weak periodic signal.

All three methods can obtain weak periodic signals and analyze key indicators such as heart rate, blood pressure, blood oxygen, and respiration.

(1) Alleviate or eliminate symptoms: Most patients with arrhythmia have certain symptoms, including palpitations, chest tightness, precordial discomfort, weakness and other symptoms, which even affect sleepiness, work, rest and daily life. If treated in time, the above symptoms can be alleviated or disappeared, which is effective in improving the quality of life of patients.

(2) Prevention of sudden death: Sudden cardiac death is a common clinical form of death. Among patients with heart disease, coronary heart disease has the highest rate of sudden death, accounting for 80% of the rate of sudden cardiac death. According to statistics, every year in the United States, there are sudden cardiac death occurs in 300,000 to 600,000 people, accounting for 40% to 50% of all deaths from heart disease. Among the cases of sudden death, 80% to 90% of the patients died of tachy ventricular arrhythmia complicated by ventricular fibrillation. The remaining 10% to 20% are bradyarrhythmias and electromechanical dissociation (the electrocardiogram shows electrical activity but no heart sounds are heard, mostly caused by a ruptured heart). Therefore, antiarrhythmic treatment is very necessary and plays a certain role in preventing sudden death.

(3) Maintain normal or near-normal blood circulation: A normal heart has good compensatory and regulatory capabilities. When the heart rate increases to 180 beats/min, it can continue to increase cardiac output. When the heart rate slows down to 35 beats/min, or even 30 beats/min, it can maintain sufficient cardiac output, maintain normal blood circulation, and keep blood pressure in the normal or close to normal range. However, if the heart has pathological changes and the cardiac function is not normal, it will lose its ability to compensate and regulate, resulting in a decrease in cardiac output, a drop in blood pressure and blood circulation disorders. If the atrial systolic function is abnormal, or the atrial and ventricular systolic procedures are changed, the cardiac output can be reduced by about 30%, causing symptoms such as palpitations, chest tightness, and weakness. Depending on the condition, different treatment methods such as drugs, electrical defibrillation, radiofrequency ablation or the installation of pacemakers are used to correct the arrhythmia and maintain normal or near-normal blood circulation.
