- ECG (Electrocardiogram) is a test that records the electrical activity of the heart and helps doctors know if the heart is beating normally or if there are problems like irregular heartbeat or heart attack.
- It is quick, painless, and done by placing small stickers (electrodes) on the chest, arms, and legs, which are connected to a machine that draws a line graph showing the heart’s rhythm.
- Doctors use ECG to check chest pain, dizziness, shortness of breath, or as part of a routine checkup for heart health, especially for people with high blood pressure, diabetes, or a family history of heart disease.
