Question
Chapter 34.4, Problem 2CC
Summary Introduction
To determine:
The importance of delay of electrical impulse by AV node by moving through SA node and atria to ventricles.
Introduction:
The association of organized cardiac muscle cells, which got specialized in their functioning, is called cardiac conduction system. The cardiac excitation originating from sinoatrial node and depolarizing in Purkinje fibers is called cardiac impulse.
