Physiology of cardiac conduction and contractility

Cardiac conducting system  Clin Anat. 2009 Jan;22(1):99-113. Can J Anaesth. 1993 Nov;40(11):1053-64. Sinoatrial (SA) node normally generates the action potential, i.e. the electrical impulse that initiates contraction. The SA node excites the right atrium (RA), travels through Bachmann’s bundle to excite left atrium (LA). The impulse travels through internodal pathways in RA to the atrioventricular (AV) node. … Continue reading Physiology of cardiac conduction and contractility
