A number of recent publications have raised concern regarding in-flight pacemaker dysfunction during air medical transport. Unfortunately the clinical importance of this problem is unknown. The authors' purpose was to examine the incidence of pacemaker use and malfunction during helicopter air medical transport, using an incidence (cohort) study of an air medical service of a tertiary-care teaching hospital. During the study period, April 1, 1987 through December 31, 1991 2,388 patients were air-transported. Cardiac patients constituted 72% of the total population. Pacemakers were used in 44 patients, temporary transvenous pacemakers in 35, permanent transvenous in five, and transcutaneous pacers in four patients. No rate-responsive pacemakers were transported. No episodes of pacemaker malfunction were observed (95% confidence interval 0 to .002 for the population as a whole). The authors conclude that pacemaker dysfunction during air medical transport is a very rare occurrence, in part due to the infrequent transport of patients requiring these devices.
最近的一些出版物引发了人们对空中医疗运输期间植入式心脏起搏器功能障碍的关注。遗憾的是，这个问题的临床重要性尚不清楚。作者的目的是通过对一家三级护理教学医院的空中医疗服务进行发病率（队列）研究，来调查直升机空中医疗运输期间起搏器的使用情况和故障发生率。在1987年4月1日至1991年12月31日的研究期间，共有2388名患者通过空中转运。心脏疾病患者占总人数的72%。44名患者使用了起搏器，其中35名使用临时经静脉起搏器，5名使用永久经静脉起搏器，4名使用经皮起搏器。没有运输具有频率适应性的起搏器。未观察到起搏器故障事件（总体人群的95%置信区间为0至0.002）。作者得出结论，空中医疗运输期间起搏器功能障碍是非常罕见的情况，部分原因是需要这些设备的患者空中转运较少。
