cardiac conduction system pdf
The cardiac conduction system is a network of specialized cells that initiate and regulate the electrical impulses controlling the heartbeat. It ensures synchronized contractions‚ enabling efficient blood circulation. The sinoatrial (SA) node acts as the natural pacemaker‚ while the atrioventricular (AV) node and His-Purkinje system facilitate impulse propagation. This system is crucial for maintaining normal heart rhythm and function. Disorders in this system can lead to arrhythmias and other cardiac complications‚ emphasizing its clinical significance. 1.1 Overview of the
