disturbances of AV conduction(passive) is caused byProlonged PR - interval
First - degree heart block indicates a delayed conduction somewhere between the junctional tissue and the Purkinje networkcausinga prolonged PR interval
Very early PACs may find the AV junction still partially refractory and unable to conduct at a normal rateresultingin a prolonged PR interval
First degree atrioventricular heart block occurs when the AV node impulse is delayedthus leadingto a prolonged PR interval
Since the PR interval is determined by atrial , AV nodal , and His - Purkinje activation , delay in any one or more of these structurescan contributeto a prolonged PR interval
