Updated: Aug 18, 2021

What is an electrocardiogram?

An electrocardiogram is a simple, painless test that measures your heart's electrical activity. It is also called an electrocardiogram. Each heartbeat is triggered by an electrical signal that starts at the top of the heart and travels to the bottom. Heart problems usually affect the electrical activity of the heart. If there are symptoms or signs that may indicate a heart problem, the doctor may advise the patient to check the electrocardiogram, especially when the following symptoms appear

· Chest pain

· Difficulty breathing

· Feeling tired or weak

· Your heart is pounding and rushing

· Feel your heart beating unevenly

· An abnormal sound is detected when your doctor listens to your heart

The electrocardiogram will help the doctor determine the cause of the symptoms and the type of treatment that may be needed.

If the patient is 50 years of age or older, or has a family history of heart disease, the doctor may also order an electrocardiogram to look for early signs of heart disease.

What happens during the ECG?

The ECG is fast, painless and harmless. The doctor will attach 12 to 15 soft electrodes with gel to your chest, arms and legs. The technician needs to ensure that the electrodes are properly attached to your skin. Each electrode is approximately one-quarter the size. These electrodes are connected to wires and then to the electrocardiograph.

During the test, the patient needs to lie quietly on the table, and the machine will record the patient's electrical activity of the heart and put the information on the chart. Make sure to lie down as much as possible and breathe normally. Don't speak at the same time. After the operation, remove and discard the electrode. The whole process takes about 10 minutes.

Types of ECG

The electrocardiogram will record the waveform of the patient's heart's electrical activity during the monitoring period. However, some heart problems come and go. In these cases, patients may require longer or more specialized monitoring. For example, during exercise, some heart problems will only appear during exercise. During the stress test, the patient will have an ECG while exercising.

Holter monitor

Holter monitors or ECG monitors can record the heart activity of the patient within 24 to 48 hours, as well as the activity of the patient to help the doctor determine the cause of the symptoms. Electrodes connected to the patient's chest record information on a portable battery-powered monitor, which the patient can put on a pocket, waist belt or shoulder strap. This portable ECG monitor is deeply loved by patients. In addition to this portable

Use some high-end smart watches or smart watches with ECG monitoring function for monitoring.

Since Apple launched the watch series, its health functions have been continuously improved from heart rate to ECG monitoring. At the same time, since the launch of the Apple watch series, other major manufacturers, whether it is Huawei, Samsung, Xiaomi, OPPO, etc., or Huami, Fitbit, Garmin, Veepoo, etc., are also promoting smart watches, and the general trend direction is the same. Health monitoring direction. The ECG monitoring function shines in these high-end smart watches. ECG can monitor the wearer's heart condition anytime and anywhere. That is, the wearer does not need to go to the hospital, but also can complete the ECG monitoring to protect the heart health at all times.

Event recorder

Symptoms that occur infrequently may require an event recorder. It will record your heart's electrical activity when symptoms appear. Some event recorders are automatically activated when symptoms are detected. Other event recorders require you to press a button when you feel symptoms. You can send the information directly to your doctor via the phone line.

For now, the ECG monitoring function of smart watches is the most convenient device for heart monitoring. The high-end smart watches on the market can basically satisfy. In particular, Weiyibao and the wearable device that focuses on health monitoring-Watch RIG will be launched in mid-2021. This product is equipped with many health functions focusing on ECG monitoring. The ECG monitoring function is combined with the Lorentz Heart Health Analysis. Method, can fully track the state of heart health.
