Overview
Recommendations for management of bradycardia associated atrioventricular block |
(Class III (Harm), Level of Evidence C): |
❑ Permanent pacing is not recommended in patients with first degree atrioventricular block or mobitz type 1 second degree atrioventricular block (wenchebach), or 2:1 atrioventricular block when the level of block is in atrioventricular node or symptoms are not related to atrioventricular block |

❑ Ambulatory electrocardiographic monitoring is recommended in patients with first degree AV block, or mobitz tyoe 1 second degree AV block to establish the correlation between symptoms related to bradycardia (lightheadness, syncope) and atrioventricular block

❑ Exercise treadmill test is reasonable in patients with first degree AV block or mobitz type 1 second degree AV block in resting ECG who have chest pain or shrtness of breath during exercise to identify the benefit of permanent pacing

❑Atripine, procainamide, isoproternole, carotide sinus massage may be used in selected patients with second degree AV block to determine the level of block and benefit from permanent pacing
