What is an EKG?

An electrocardiogram — abbreviated as EKG or ECG — measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This electrical wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the rate and rhythm of the contractions in the upper and lower chambers.

The right and left atria or upper chambers make the first wave called a “P wave" — following a flat line when the electrical impulse goes to the bottom chambers or ventricles. The right and left bottom chambers make the next wave called a “QRS complex." The final wave, or “T wave,” represents electrical recovery or return to a resting state for the ventricles.
