Overview
Overview
Commonly, there is no need for treating first-degree AV block. Permanent pacemaker indicates only for symptomatic first-degree AV block with PR>300 ms,neuromuscular disease, or in presence of wide QRS compelex. First-degree AV block in the setting of acute myocardial infarction usually reverses after recovery from acute phase of myocardial infarction. Antiarrhythmic medications should be avoided in first-degreeAV block.
