移动电话对埋藏式永久起搏器干扰的临床研究

目的 :研究移动电话对埋藏式永久起搏器的干扰情况。方法 :用自身对照法 ,将国内常用的 2种移动电话分别放在 3种不同位置及处于不同工作状态下 ,检测其对埋藏式起搏器的干扰情况。结果 :对 110例患者共进行 185 7次测试 ,仅 1例 (0 .9% ) Biotronic Ergos- 0 1VVI型起搏器依赖型患者 2 2次 (1.2 % )出现干扰。干扰只发生在移动电话处于起搏器上 ,且多出现于铃响阶段。数字机干扰大于模拟机。当移动电话处在正常耳旁位置时未见干扰。结论 :目前的埋藏式心脏起搏器对移动电话具有一定的抗干扰能力 ;起搏器患者在通常耳旁位置使用移动电话是安全的 ;起搏器依赖型患者最好选用模拟式移动电话。

Interference of cellular phones on implanted permanent pacemaker

Objective:To investigate the interference of cellular phones on implanted permannet pacemaker.Mothod:By self contrasted method,110 patients with implanted pacemakers were interfered by two types of cellular phones in vivo. Each phone was placed at three different position and was in different state of work.Result:Among 1 857 interference tests, which were determined in 110 patients, 22 ( 1.2 %) episodes were demonstrated in only one pacemaker dependent patient with Biotronic Ergos 01 VVI type. All interference occurred only when the cellular phone was positioned above the pacemaker pocket.The most interference was observed during and before the ringing. Both the digital and analog cellular phone can lead to interference, but the former predominated the latter. No interference was seen when the cellular phone was placed on the ear. Conclusion:It is suggested that the new generated implanted pacemaker could protect interference from cellular phone, but few patient may be interfered. When they use the cellular phone on one ear in the normal position, patients would be considerably safe.It is better for pacemaker dependent patients to select the analog cellular phone.
