Components of an electrocardiogram (ECG) tracing reflecting the electrical activity of the heart, including various waves (P wave, QRS complex, T wave) associated with specific phases of cardiac depolarization and repolarization.

ECG

Electrocardiogram, a test that records the heart’s electrical activity and can be used to diagnose various heart conditions.

QRS Complex

A series of deflections in an electrocardiogram representing the electrical activity associated with the ventricular contraction of the heart.

P Wave

The waveform on an electrocardiogram (ECG) that represents atrial depolarization, preceding the contraction of the atria.
