Pacemaker action potentials were recorded in the region identified by mapping as the origin of the impulse in 11 of 11grafts. Action potentials recorded from surrounding working cells were similar to adult rat heart cells in maximum diastolic potential, over- shoot, amplitude, and duration. In ...
Each heart beat or contraction is initiated by generation of an action potential in the SA node; the electrical impulse spreads over both atria, causing them to contract, and on to the atrioventricular (AV) node. From the AV node it spreads through the bundle of His and down the Purkinje ...
Sick sinus syndrome (SSS) occurs from sinoatrial node dysfunction is the most common indication for permanent pacemaker implantation. The second most common indication for a permanent pacemaker is atrioventricular (AV) nodal disease such as second degree type II AV block or third degree heart block....

The proper expression and function of the cardiac pacemaker is a critical feature of heart physiology. The sinoatrial node (SAN) in human right atrium generates an electrical stimulation approximately 70 times per minute, which propagates from a conducti
