CONDUCTING SYSTEM OF HEART

Conducting system of heart consists of Sinoarterial (SA) Node, Internodal Pathway, Atrioventricular (AV) node, His Bundle. Bundle branches and Purkinje Fibers. Conduction is Fastest in Purkinje Fibers. Depolarization initiated in SA node spreads radially through the atria. INTERNODAL & INTERATRIAL PATHWAYS TRANSMIT CARDIAC IMPULSES THROUGH THE ATRIA THE AV NODE DELAYS IMPULSE CONDUCTION FROM ATRIAContinue reading “CONDUCTING SYSTEM OF HEART”
