Your doctor will diagnose a heart attack based on your signs and symptoms, your medical and family histories, and test results. An EKG is a simple, painless test that detects and records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through each part of the heart. An EKG can show signs of heart damage due to coronary heart disease (CHD) and signs of a previous or current heart attack.
