What is A graph detecting the electrical chamges in the heart as it beats?

A graph that detects electrical changes in the heart as it beats is called an electrocardiogram (ECG or EKG). It records the electrical activity of the heart over time, providing insights into the heart's rhythm and function. The resulting waveform displays the different phases of the heartbeat, including depolarization and repolarization of the heart's muscle cells. Clinicians use this information to diagnose various heart conditions and monitor overall cardiac health.
