Electrocardiogram (ECG) is a painless, non-invasive test that records the electrical activity of your heart. This essential diagnostic tool helps detect heart rhythm abnormalities, heart attacks, and other cardiac conditions.
Understanding your heart's electrical activity
An ECG is a simple, painless test that measures the electrical signals that control your heartbeat. Small electrodes are placed on your chest, arms, and legs to record the heart's electrical activity. This test helps:
Identifies irregular heartbeats, arrhythmias, and conduction disorders
Shows evidence of previous or current heart attacks and heart muscle damage
Provides baseline information for ongoing cardiac care and treatment monitoring
