Intraoperative occurrence of bradyarrhythmia in a patient with asymptomatic bifascicular block.

摘要

To the editor: Recent reports do not recommend routine prophylactic temporary pacemaker placement in patients with asymptomatic complete right bundle branch block with left axis deviation (bifascicular block) during noncardiac surgery because of the low rate of occurrence of block progression and the lack of cost-effectiveness [1,2]. We would like to report a case of the intraoperative occurrence of bradyarrythmia in an anesthetized patient with asymptomatic bifascicular block. This bradyarrythmia was successfully treated with a pulmonary artery catheter (PAC) with electrodes for pacing.
