ECG (Electrocardiography) is a diagnostic test used to measure and record the electrical activity of the heart. During the test, small electrodes are placed on the chest, arms, and legs to capture electrical signals generated by the heart as it beats.

These signals are displayed as waveforms on a monitor or printed report, allowing healthcare providers to evaluate heart rhythm, rate, and overall cardiac function. The ECG helps identify irregular heartbeats (arrhythmias), heart enlargement, conduction abnormalities, and signs of reduced blood flow to the heart.

It is one of the most commonly performed cardiac tests due to its simplicity, speed, and effectiveness. The procedure is painless, non-invasive, and usually completed within a few minutes.

ECG is widely used in routine health check-ups, emergency situations, and ongoing monitoring of heart conditions.

The purpose of ECG is to assess the electrical activity and function of the heart.

It helps to:

• Detect irregular heart rhythms (arrhythmias)
• Assess heart rate and rhythm
• Identify signs of heart attack or ischemia
• Detect enlargement of heart chambers
• Evaluate conduction abnormalities
• Monitor existing heart conditions
• Assess heart health during routine check-ups
