Abstract

Temporary external pacemakers have been reported to fail under hyperbaric conditions. In this study we investigated cardiac pacing under hyperbaric conditions. Permanent hermetically sealed pacemakers were found to function well under hyperbaric conditions, while several models of temporary external pacemakers failed. The electrical characteristics of pacing leads did not change under hyperbaric conditions. External pacing under hyperbaric conditions may be accomplished safely by using a permanent pacemaker attached to the patient's temporary external leads.

摘要

据报道，临时体外起搏器在高压环境下会出现故障。在本研究中，我们对高压环境下的心脏起搏进行了调查。结果发现，永久性密封起搏器在高压环境下功能良好，而几种型号的临时体外起搏器出现了故障。起搏导线的电学特性在高压环境下没有改变。在高压环境下进行体外起搏时，使用连接在患者临时体外导线上的永久性起搏器可安全完成。
