P-R Interval

A measurement in electrocardiography that represents the time between the onset of atrial depolarization and the onset of ventricular depolarization.

Countershock

Cardiac Depolarization

An event in the cardiac cycle where the heart's muscle cells become electrically charged, leading to muscle contraction and heartbeat.
