Electrophysiology of the Heart

Some tissues such as heart and nerves are able to generate electrical signals without external electrical stimulation.Heart's electrical impulses are conducted by two types of cardiac tissues ,a specialized cardiac conduction system .including sinoatrial Node or SA node,inter nodal track,Atrioventricular Node(AV node),Bundle of HIS, right and left Bundle branches,purkinje network and myocardium.
SA node the primary pacemaker of the heart exhibits rapid automaticity firing at regular rate and causes heart to be at rhythmically.Electrical impulses generated other than the SA nodes are abnormal and disrupts the normal heart rhythm
