The main manifestation of abnormal ECG is that it presents waveforms or rhythms that are different from normal conditions, and these abnormalities may prompt doctors about the patient’s heart health issues. The following are some typical ECG abnormalities：

Atrial fibrillation: When atrial fibrillation occurs, ECG images typically display fast, irregular, without significant P-waves and multiple small oscillations of QRS waves.

Ventricular fibrillation: On ECG, ventricular fibrillation typically manifests as oscillations between high frequencies (>300 beats/minute) and irregular intervals, without significant QRS waves.

Left deviation of the electrocardiogram axis: When some tissues in the human body are damaged, resulting in a large number of muscle fiber deaths and other problems, it can cause lateral disorders. ECG can detect this impact and display it as a decrease in R to S values in SR mode and tilt to the left.

ST-T changes: ST-T changes can indicate the presence of coronary artery disease or other vascular diseases in patients. In such cases, phenomena such as ST segment elevation or depression and T-wave inversion can be observed in ECG.

The above are some common ECG abnormalities, but the specific manifestations may vary depending on individual circumstances. If you have any heart health issues, please consult a professional doctor.

Understanding an ECG requires some professional knowledge and here are a few basic steps that beginners can follow：

1.Confirm the lead: ECG usually consists of 12 leads. Before examining the ECG, make sure you’re looking at the correct lead.

2.Observe waveforms: A normal ECG should contain P-waves, QRS complexes, and T-waves. These different waveforms reflect the electrical activity of the heart during different phases in one cardiac cycle.

3.Analyze rhythm: A normal ECG should show sinus rhythm(which means steady and regular beats controlled by sinoatrial node). If there’s no sinus rhythm, further analysis is needed to determine whether there are other types of arrhythmias or heart rate problems.

4.Detect ST segment changes: The ST segment represents a horizontal line formed after minor oscillations caused by left ventricular pressure and coronary artery perfusion during systole to diastole period; its abnormality may indicate ischemia or acute coronary syndrome.

5.Look for other special markers: Find corresponding markers in ECG according to doctor’s instructions or focus on specific situations for analysis.

Overall, understanding and interpreting an ECG requires experience and professional knowledge. If you need more detailed explanations or have any questions, please consult with your doctor or other professionals.

Here is a free APP – “AFibCheck“, which can be downloaded and used after searching in the mobile app store. It is simple and convenient to operate.

An ECG recorder can detect the following aspects：

1.Heart rhythm: The ECG can display the heart’s rhythm and rate. If you feel discomfort or concern, a doctor can use the ECG to determine if there is an abnormal heart rate.

2.Myocardial ischemia: When coronary artery blood supply is insufficient, it may lead to myocardial ischemia, which is a serious condition. The ECG can help diagnose whether there is myocardial ischemia and determine its severity.

3.Abnormal ventricular wall motion: In some cases (such as aortic regurgitation), left ventricular dysfunction may cause problems such as increased end-diastolic volume of the left ventricle and decreased contractile ability，which are related to specific manifestations that could be detected by an ECG.

4.Oxygen uptake test results: An oxygen uptake test is typically used for evaluating patient oxygen content level and respiratory function status while an ECG monitors changes occurring during this test.

5.Other applications include sleep monitoring, exercise fitness etc..In summary, an ECG is a simple yet effective diagnostic tool that plays an important role in diagnosing and treating many diseases in various fields of application.

When choosing an ECG recorder, the following aspects can be considered:

1. Purpose: Firstly, the purpose of using an ECG recorder needs to be considered. For example, if you are a doctor or nurse, you need a high-precision, reliable, and easy to operate recorder; If you just want to self monitor at home, you can choose a more affordable and portable device.

2. Function: Different models and brands of electrocardiogram recorders have different functions. Therefore, before purchasing, one should understand the functions they provide and make corresponding choices based on their needs. For example, some devices may be compatible with smartphones and able to transmit data to cloud platforms for better tracking of changes in medical conditions.

3. Quality: Quality is one of the most important considerations. Products manufactured with high quality, certified, and standardized program specifications.

4. Mobility: If you need to carry this device with you to other places, then lightweight and convenient portability have become a very important factor

5. Price: The price of ECG recorders ranges from hundreds to thousands of yuan, and consumers can choose based on their own budget and needs.

When purchasing an ECG recorder, one should weigh the above factors based on personal circumstances and purchase products that meet the requirements. At the same time, before using an ECG recorder, it is best to consult a professional doctor and understand the correct operating methods and how to read and analyze data.

The normal range of ECG monitoring should show the following features：

1.Regular heart rhythm: The time between each contraction and relaxation should be the same.

2.P wave: The P wave represents atrial contraction, which should have a clear and regular shape under normal conditions.

3.QRS complex: The QRS complex represents ventricular muscle contraction, and its duration is usually 0.06 to 0.10 seconds.

4.ST segment and T wave: The ST segment and T wave reflect the process of ventricular repolarization (returning to the initial, and their shapes should also fall within the normal range.

If you undergo ECG monitoring and find that your results differ from these standards, it may be necessary to seek help from a professional doctor for more detailed and accurate interpretation.

ECG monitoring data can be analyzed and interpreted by examining the ECG waveform. Typically, a doctor will evaluate the ECG based on several aspects：

1.Heart rate rhythm: The doctor will check whether the time between each contraction and relaxation is regular.

2.P wave: The doctor will examine characteristics such as shape, size, and duration of P waves to assess atrial contraction.

3.QRS complex: The doctor will examine characteristics such as shape, size, and duration of QRS complexes to assess ventricular muscle contraction.

4.ST segment and T wave: The doctor also pays attention to ST segments and T waves reflecting ventricular repolarization process if they are normal.

In addition, there are other indicators that need to be considered too. For example, QT interval (from Q point to T end) is an important indicator used for assessing cardiac health status in patients. If the QT interval is prolonged it may indicate certain issues that require further diagnosis or treatmentIn summary, when observing ECG monitoring data please consult a professional (such as a cardiologist), obtain detailed information about your condition for accurate diagnosis purposes.

The principle of ECG monitoring is to use electrodes to record the small electrical signals generated by the heart’s activity on a patient’s body, and then convert these signals into visual ECG waveforms through amplification and filtering techniques.

During an ECG monitoring procedure, healthcare providers attach several leads to different locations on the patient’s body. These leads act as receivers that can capture the weak electric currents emitted by the heart, and transmit them to an ECG machine. The machine processes and analyzes this data, generating a chart or digital record that reflects key parameters such as heart rhythm, rate, and other relevant information.

It should be noted that while ECG monitoring can help doctors diagnose certain conditions or abnormalities, it cannot replace comprehensive examination and professional medical evaluation. If you have any health concerns, be sure to consult with a qualified healthcare provider for accurate advice and treatment plans.
