An ECG can detect abnormalities in your heart's rhythm and certain patterns that suggest portions of the heart may not be getting enough blood flow. The ECG may also show whether you are having a heart attack or find evidence of a previous heart attack. However ECGs are not perfect tests.
An electrocardiogram, also called an ECG or EKG, is a simple, painless test that detects and records your heartâs electrical activity. An EKG can show how fast your heart is beating, whether the rhythm of your heartbeats is steady or irregular, and the strength and timing of the electrical impulses passing through each part of your heart.
