The electrical impulse moves across the right and left atrium in the direction of the AV node. This conduction is known as atrial depolarisation (electrical event) and results in atrial contraction (mechanical event). WebNormal cardiac rhythm is established by the sinoatrial (SA) node, a specialized clump of myocardial conducting cells located in the superior and posterior walls of the right atrium in close proximity to the orifice of the superior vena cava. The SA node has the highest inherent rate of depolarization and is known as the pacemaker of the heart. boxer puppies for adoption pennsylvania

Sa and av node electrical conduction

WebElectrical signals arising in the SA node (located in the right atrium) stimulate the atria to contract. Then the signals travel to the atrioventricular node (AV node), which is located … WebNormal electrical conduction through the heart muscle takes a predicted pathway. It travels from the Sinoatrial node (SA node) to the Atrioventricular node (AV node) to the Bundle of His and then onto the left and right bundle branches (usually in a left to right pattern), ultimately ending up in the Purkinje fibers.
