The widespread use of cellular phones in the last years has prompted some recent studies to suggest an interference of pacemaker function by cellular phone usage. To determine the risk of pacemaker patients using D-net cellular phones, we tested 50 patients with permanent pacemakers after routine pacemaker check by short phone calls using a cellular phone (Ericsson, D-net, frequency 890-915 MHz, digital information coding, equivalent to the European Groupe Systemes Mobiles standard). A six-channel surface ECG was continuously recorded from each patient to detect any interactions between pacemakers and cellular phones. Phone calls were repeated during the following pacemaker settings: (1) preexisting setting; (2) minimum ventricular rate of 90 beats/min and preexisting sensitivity; and (3) minimum ventricular rate of 90 beats/min and maximum sensitivity without T wave oversensing. Only 2 (4%) of 50 patients repeatedly showed intermittent pacemaker inhibition during calls with the cellular phone. Both pacemakers had unipolar sensing. Therefore, although interactions between cellular phone use and pacemaker function appear to be rare in our study, pacemaker dependent patients in particular should avoid the use of cellular phones.
近年来手机的广泛使用促使一些近期研究表明使用手机会干扰起搏器功能。为了确定起搏器患者使用D网手机的风险，我们在对50名植入永久性起搏器的患者进行常规起搏器检查后，让他们使用手机（爱立信，D网，频率890 - 915兆赫，数字信息编码，等同于欧洲移动系统标准）进行短时间通话来进行测试。持续记录每位患者的六通道体表心电图，以检测起搏器与手机之间的任何相互作用。在以下起搏器设置期间重复进行通话：（1）原有设置；（2）心室率最小值为90次/分钟且原有灵敏度；以及（3）心室率最小值为90次/分钟且最大灵敏度且无T波过度感知。50名患者中只有2名（4%）在使用手机通话期间反复出现间歇性起搏器抑制。两个起搏器均为单极感知。因此，尽管在我们的研究中手机使用与起搏器功能之间的相互作用似乎很少见，但特别是依赖起搏器的患者应避免使用手机。
