The graphic record of the heart's electrical activity is known as what?

Explanation:
The graphic record of the heart's electrical activity is an electrocardiogram. This device records the electrical impulses that coordinate heartbeats by placing electrodes on the body, producing a waveforms that reflect atrial depolarization (P wave), ventricular depolarization (QRS complex), and ventricular repolarization (T wave). These traces help diagnose rhythm issues, conduction problems, and ischemia. Other terms describe different things: a cardiac cycle is the mechanical sequence of atrial and ventricular contraction and relaxation; an echocardiogram uses ultrasound to image heart structure and motion; a pulse tracing measures the pulse in a peripheral artery rather than the heart's electrical signals.
