Category: ECG/EKG Applications

If a patient has signs or symptoms of a heart problem, such as an irregular heartbeat (arrhythmia) or unexplained fainting, their doctor may order a test called an ECG. An ECG is a brief, non-invasive test that uses electrodes taped to the chest to check the heart’s rhythm. However, sometimes an ECG doesn’t detect any irregularities in the heart rhythm because the patient is connected to the ECG machine for only a short time. If their signs and symptoms suggest that an occasionally irregular heart rhythm may be causing their condition, the doctor may recommend the wearing of a Holter monitor for up to 24 hours. Over that time, the Holter monitor may be able to detect irregularities in the heart rhythm that an ECG couldn’t detect. The doctor may also order a Holter monitor if you the patient has a heart condition that increases your risk of an abnormal heart rhythm.

A 24 hour Holter monitor is a battery-operated portable device that measures and records your heart’s ECG activity continuously for 24 to 48 hours (or even longer) depending on the type of monitoring used. The device is usually about the size of a small camera.

There are several reasons why heart rhythm monitoring might be recommended. It’s most often needed when there is a question about whether you have a heart rhythm issue that a standard ECG hasn’t or most likely won’t picked up.

Some common reasons are if you have:

1.Heart palpitations. For example, if you notice your heart is flip-flopping or beating unevenly or very quickly. Many heart palpitations aren’t serious and are more of a nuisance (for example with premature ventricular contractions, or PVCs, which are “extra” heartbeats). Still, it’s important to know what is happening with your heart, and whether you need any follow-up visits.

2.Other symptoms – for example dizziness or feeling faint – that suggest you might have atrial fibrillation or another heart rhythm disorder.

3.Unexplained fainting spells, stroke, or mini strokes.

4.A family history of or existing heart disease. Heart rhythm problems are common among people with heart disease, but many people may not have clear symptoms and may even have a normal ECG. Finding a heart rhythm problem early can help prevent other complications.

5.Had a recent heart-related event or treatment to be able to monitor your heart activity for any irregular or dangerous rhythms after:

1.Starting or stopping a heart medicine;

2.An ablation;

3.A heart attack;

4.Finding out you have hypertrophic cardiomyopathy or other heart problems linked to heart rhythm disorders.

Heart monitors can help:

1.Record your heart’s activity as you go about your usual day. A heart monitor can cover a much longer period of time than is possible with an ECG in your doctor’s office. (Those tend to provide only 10-15 seconds of activity).

2.Pick up on irregular heart rhythms that don’t happen very often and that a standard ECG can miss. Many offbeat heart rhythms can come and go quickly. If you have symptoms while you are wearing a monitor, it can help give you and your care team answers.

3.Detect irregular heartbeats that you may not be aware of if you don’t have symptoms.

4.Give peace of mind that your care team will see any changes to your heart’s electrical activity and figure out if your symptoms are, in fact, related to your heart.

Over time, heart monitors have become much smaller and less cumbersome. Today, many can be sent back in the mail for added convenience.

Regular ECGs or EKGs let your doctor look at your heart’s activity at one point in time during your ECG test. But abnormal heart rhythms and cardiac symptoms may come and go. That’s why your doctor may want to evaluate your heartbeat over time while you go about your normal activities. You may be asked to wear a Holter monitor if you have fast, slow or irregular heartbeats called arrhythmias.

Wearing the monitor may tell your doctor:

1.If your medicines are working;

2.Why you have symptoms such as dizziness, faintness or the feeling that your heart is racing or skipping a beat;

3.If your heart is getting enough oxygen to meet its needs.

A Holter monitor is a portable device that many doctors prescribe patients to wear when they need to solve a medical mystery. The monitor allows doctors to measure the heart’s rate and rhythm in order to determine how a patient’s heart is functioning. It is typically worn between 24 and 48 hours while patients continue throughout their normal days. There are a number of reasons why your doctor may require you to wear a Holter monitor.

ECG are generally performed if the patient experiences an abnormal heart rhythm. An ECG measures heart rate and rhythm but these abnormalities may not show up at the time of the the examination since the test only lasts several minutes, which is why many doctors may request that you wear a Holter monitor for an extended period of time to diagnose an arrhythmia, or irregular heartbeat.

Doctors may also order you to wear a Holter monitor if you have a heart condition that may increase the likelihood of an abnormal heart rhythm. They may also request that you keep a diary of the activities you are performing throughout the day. A Holter test may provide more information that could explain dizziness or fainting and palpitations or the feeling that your heart is fluttering.

Unlike the event monitor, which only records when you experience an “event” or abnormal symptom, the Holter monitor continuously records for the entire period that you wear it. Paired with the beat-by-beat record and your diary, your doctor is able to diagnose the problems that may be causing your irregular symptoms.

a Holter monitor can potentially detect heart blockage. A Holter monitor is a type of monitor used to monitor and record a patient’s heart rhythm for 24 to 48 hours. It can measure indicators such as heart rate and rhythm, blockages, and other abnormal cardiac activity.

During the monitoring period, information is collected that can help in the diagnosis of certain heart problems, such as heart blockages in the arteries or slow, fast, or abnormal heart rhythms. While the Holter monitor can potentially detect heart blockage, it is important to note that it is a noninvasive method of monitoring and is not considered a definitive diagnosis.

A more definitive diagnosis would require additional testing, such as an EKG or angiogram, to further assess the patient’s condition.

1. Left atrial hypertrophy

The P-wave widens and appears as a bimodal pattern, with the most prominent in leads I, II, and aVL, also known as mitral valve type P-wave. The PR segment is shortened, and the P-wave in lead V1 first appears positive, followed by a deep and wide negative wave.

2. Right atrial hypertrophy

The P-wave is sharp and towering, with an amplitude greater than 0.25mV. Due to the increase of the downward P-vector, it is most prominent in leads II, III, and aVF of the electrocardiogram, known as the “lung type P-wave”.

3. Left ventricular hypertrophy

(1) The QRS complex voltage increases: RV5>2.5mV, RV5+SV1>4.0mV (male) or>3.5mV (female).

(2) The electrocardiogram axis deviates to the left.

(3) The QRS complex time was extended to 0.10-0.11 seconds.

(4) ST-T changes, with R waves dominant in leads, where T waves are low, flat, bidirectional, or inverted.

4. Right ventricular hypertrophy

(1) V1 lead R/S>1, V5 lead R/S<1, and the QRS complex of V1 or V3 R shows RS, RSR ′, R, or QR patterns.

(2) RV1+SV5>1.2mV, R/Q or R/S>1 for aVR leads, RaVR>0.5mV.

(3) The electrocardiogram axis deviates to the right, and in severe cases, it can be>+110 °.

(4) V1 or V3 R and other right chest leads have ST-T downshifting>0.05mV, and T-waves are low, flat, bidirectional, or inverted.

5. Myocardial infarction

(1) Ischemic T wave changes: Ischemia occurs on the endocardial surface, with high and upright T waves; If it occurs on the epicardial surface, symmetrical T-wave inversion occurs.

(2) Injury type S-T segment change: The leads facing the injured myocardium show elevation of the S-T segment, which can form a single-phase curve with significant elevation.

(3) Necrosis type Q-wave appearance: Abnormal Q-waves (width ≥ 0.04s, depth ≥ 1/4R) or QS waves appear in leads facing the necrotic area.

6. Atrial premature contractions

(1) The early appearance of atrial P ‘differs in morphology from sinus P wave.

(2) P ′ – R interval ≥ 0.12s.

(3) There is a normal QRS complex after atrial P ‘wave.

(4) Intermittent compensation is incomplete.

7. Ventricular premature contractions

(1) The QRS-T complex with early onset of broad malformations does not have any ectopic P-waves before it.

(2) The QRS time limit is often ≥ 0.12s.

(3) The direction of the T-wave is opposite to the direction of the QRS main wave.

(4) There are often complete compensatory intervals.

8. Junctional premature contractions

(1) The QRS complex that appeared in advance has a basically normal morphology.

(2) The occurrence of retrograde P ‘wave can occur before QRS (P’ – R<0.12s), after QRS (R-P ‘<0.20s), or overlap with QRS.

(3) There are often complete compensatory intervals.

9. Paroxysmal supraventricular tachycardia

(1) Equivalent to a series of continuous and rapid atrial or junctional premature beats, with a frequency of 150-250/min and a regular rhythm.

(2) The QRS complex morphology is basically normal, with a time of ≤ 0.10s.

(3) There is no change in ST-T, or the S-T segment shifts downward and the T-wave is inverted during the onset.

10. Atrial fibrillation

(1) The P-wave disappears and is replaced by F-waves of varying sizes, spacing, and shapes, with frequencies ranging from 350 to 600 beats per minute, with the V1 lead being the most prominent.

(2) The ventricular rhythm is absolutely irregular, with a ventricular rate typically between 120 to 180 beats per minute.

(3) The QRS complex morphology is usually normal. When the ventricular rate is too fast, indoor differential conduction occurs, and the QRS complex widens and deforms.

11. Ventricular fibrillation

(1) The P-wave disappears and is replaced by F-waves of varying sizes, spacing, and shapes, with frequencies ranging from 350 to 600 beats per minute, with the V1 lead being the most prominent.

(2) The ventricular rhythm is absolutely irregular, with a ventricular rate typically between 120 to 180 beats per minute.

(3) The QRS complex morphology is usually normal. When the ventricular rate is too fast, indoor differential conduction occurs, and the QRS complex widens and deforms.

12. Atrioventricular block

(1) First degree atrioventricular block: ① QRS complex is present after sinus P wave. ② The P-R interval was extended by ≥ 0.21 s.

(2) Second degree type I atrioventricular block: ① The P-wave pattern appears, and the P-R interval is gradually prolonged until ventricular leakage occurs (there is no QRS complex after the P-wave). ② After a missed beat, the P-R interval tends to shorten again, and then gradually extends until the missed beat repeats itself The time and morphology of the QRS complex are mostly normal.

(3) Second degree type II atrioventricular block: ① P-R interval is constant (normal or prolonged). ② Partial absence of QRS complex after P-wave (occurrence of ventricular leakage) The ratio of atrioventricular conduction is generally 2:1 or 3:2, etc.

(4) Third degree atrioventricular block (complete atrioventricular block): ① There is no fixed relationship between the P-wave and QRS complex, and the spacing between P-P and R-R has their own fixed patterns. ② Atrial rate>ventricular rate. ③ The QRS complex has normal or wide malformation morphology.

The above are common types of abnormal ECG. There are now portable ECG recorders (such as Plus1Health) that can monitor and record ECG in real-time at any time, automatically analyze and generate reports. There is also an ECG, which can be accessed anytime and anywhere, making it convenient for doctors to refer to.

ECG monitoring refers to the continuous or periodic measurement of a person’s heart activity using an ECG. An ECG monitor records and displays the electrical impulses generated by your heart as it beats, providing information about its rhythm, rate, and other features.

There are different types of ECG monitoring depending on the duration of recording required:

1.Resting ECG: A brief recording done while you lie still on a table or bed. Usually lasts for a few minutes.

2.Holter Monitoring: A portable device that can record your heart’s activity over 24 hours (or longer) while you go about your daily routine.

Plus1health has a portable ECG recorder,it is compact and exquisite, and it can monitor for up to 24 hours in real-time, record arrhythmia situations, automatically generate electrocardiogram and report analysis.

3.Event Recording/Loop Recorder: Similar to Holter Monitor but is usually worn for weeks or months at a time and only records when you activate it during specific symptoms like palpitations or fainting episodes.

ECG monitoring is used for various reasons such as diagnosing abnormal rhythms in the heartbeat, assessing risk factors for cardiovascular disease, evaluating medication effectiveness or side effects on cardiac function. It may also be recommended after certain procedures like pacemaker implantation and coronary artery bypass surgery to ensure proper functioning of these devices.
