Digitalis toxicity is a major cause of this rhythm,and further digitalis doses should not be given until a digitalis level is obtained.Other causes of Mobitz I include AV nodal blocking drugs,acute inferior wall myocardial infarction or right ventricular infarction,ischemic heart disease,and excess vagal response.This type of block is usually well tolerated,and no treatment is indicated unless the dropped beats occur frequently.
