Electrocardiogram (ECG) is an analysis of the heart’s functioning to diagnose cardiac abnormalities. It is a procedure of recording the electrical activity of the heart over a period of time through electrodes placed over the body.
Your doctor can recommend an ECG test if you suffer from high blood pressure or experience any heart issues. These heart issues can be heavy or irregular heartbeats, shortness of breath or chest pain.
An ECG is recommended in the following situations:
For diagnosing if a person has suffered from a heart attack or to discover any previous heart attack evidence
To determine the position and size of the chambers of the heart
For examining the treatment for coronary heart disease.
For determining irregular heartbeat, also known as arrhythmia
For diagnosing poor blood flow to the heart muscle
Evaluating specific heart abnormalities like an enlarged heart
You can need an ECG test if you show the following symptoms:
There are usually no risks associated with the test, and the procedure is safe and painless. The electrodes in your body do not emit any electricity and capture only the electrical activity inside your heart.
ECGs from healthy hearts display a characteristic shape, and any irregularity in the heart rhythm or damage to the heart muscle changes the electrical activity of the heart, changing the shape of the ECG.
The result of the ECG test will determine the type of treatment you need.
