An electrocardiogram â abbreviated as EKG or ECG â is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or âwaveâ) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers. The right and left atria or upper chambers make the first wave called a âP wave â following a flat line when the electrical impulse goes to the bottom chambers.
