Electrocardiogram (EKG) Basics - Right Ventricular MI Criteria

 Ben Taylor PhD PA-C
Description: Simple Cellular Electrophysiology: - Cardiac cells, in their resting state, are electrically polarized (negatively charged)-Maintained by membrane pumps to ensure appropriate ion distribution (K+, Na+, Cl, Ca+) to keep the inside cell electronegative. Cells lose their internal “-” during depolarization. Cells restore their resting polarity during repolarization.
