Electrocardiogram (ECG) tests play a pivotal role in diagnosing various heart conditions and monitoring cardiac health. In this guide, we delve into the intricacies of ECG tests, exploring their purpose, procedure, interpretation, and significance in modern healthcare.

What is an ECG Test?
An ECG test, also known as an electrocardiogram, is a non-invasive medical procedure used to measure the electrical activity of the heart. By recording the heart's electrical impulses, an ECG provides valuable insights into the heart's rhythm, rate, and overall function.

How Does an ECG Work?
During an ECG, small electrodes are attached to the chest, arms, and legs of the patient. These electrodes detect the electrical signals produced by the heart as it contracts and relaxes. The signals are then amplified and displayed as waves on a graph, known as an electrocardiogram.

Purpose of ECG Tests
ECG tests serve multiple purposes in cardiovascular medicine:

Diagnosis: ECGs help diagnose various heart conditions, including arrhythmias, heart attacks, and heart rhythm disorders.
Monitoring: ECGs are used to monitor the effectiveness of cardiac medications, detect changes in heart rhythm, and assess the progression of heart diseases.
Screening: In some cases, ECGs are used as part of routine health screenings to identify potential heart problems before symptoms occur.
