What is ECG? What to do? On which devices?

An ECG is often used to detect irregularities in the heart rhythm and find the cause of chest pain. So what is an ECG, what is it for and on what devices? Let’s find out with Tnhelearning.edu.vn!

What is ECG?

ECG is the English acronym for Electrocardiogram , also known as electrocardiogram.

An ECG is a curve that records the variations in electrical currents produced by the heart during contractions. An ECG can measure the heart’s speed and rhythm as well as provide indirect evidence of blood flow to the heart.

Uses of ECG – Why is it important?

The heart generates small electrical impulses that are transmitted to the heart muscle to perform the heart’s contraction. These electrical impulses can be recorded by an ECG.

An ECG helps find the cause of symptoms such as palpitations or chest pain. Heart abnormalities that may be detected include:

• Arrhythmia : very fast, very slow, or irregular heartbeat. There are many different types of arrhythmias with characteristic ECG patterns.
• Heart attack (myocardial infarction), recent or has happened in the past. A heart attack causes damage to the heart muscle and leaves a scar. These lesions of the heart can be detected by abnormal ECG patterns.
• Enlarged heart (enlarged heart). Basically, this disease produces impulses that are larger than normal.

Sometimes an ECG is performed as part of a routine test such as a preoperative test because the process is bloodless, simple, inexpensive, and can be done within 5 minutes.

Devices equipped with ECG

ECG is often fitted on medical equipment, often found in hospitals.

However, in addition to medical devices, users can fully experience ECG through handheld and smart wearable devices such as Apple’s smartwatch (Apple Watch Series 4), Xiaomi (Amazfit 2 and Health Watch). ).
