==Overview==
==Overview==
 
Common causes of second degree [[AV block]] include acute [[myocardial ischemia]] or [[infarction]], [[infiltrative]] diseases, [[collagen vascular disease]], [[surgical trauma]], [[endocrine]] abnormalities, [[autonomic]] effects, [[neuromuscular ]] disorders, and [[medication]]s.
Atrioventricular (AV) block is defined as an interruption in the transmission of an impulse, either transient or permanent, from the atria to the ventricles due to an anatomic or functional impairment in the conduction system.  In second degree AV block, some atrial impulses fail to reach the ventricles.  Wenckebach described progressive delay between atrial and ventricular contraction and the eventual failure of an atrial beat to reach the ventricles.  Mobitz subsequently divided second degree AV block into two subtypes, as determined by the findings on the [[electrocardiogram]].  In Mobitz type I AV block, progressive PR interval prolongation precedes a non-conducted P wave. While in Mobitz type II AV block, the PR interval remains unchanged prior to a P wave that suddenly fails to conduct to the ventricles.
