Basics Parts to an Electrokardiogram [EKG]

The video tutorial explains the cardiomyocyte action potential, highlighting its occurrence in individual cells and its role in the cardiac cycle. It contrasts this with the electrokardiogram (EKG), which measures the heart's overall electrical activity. The tutorial details the EKG's segments: P wave, QRS complex, and T wave, explaining their associated electrical and mechanical events. The video emphasizes the distinction between microscopic action potentials and macroscopic EKG readings, preparing viewers for practice problems on heart rate determination.
