随着医学电子工程学的飞速发展,新型起搏器的品种、功能不断增多,若不预先熟悉其性能,在某些特殊条件下,容易误判为“故障”。我们曾遇到两种起搏器安装时出现“伪频率奔放”,报告于下,以供借鉴。例1,吴某,男性、59岁,病因疑为病毒性心肌炎,3°房室传导阻滞,于1991年9月安置 ERGOS 02型埋藏式 DDDR 频率应答式起搏器,标称起搏器频率为72次/分。当导管固定后,将起搏器放入皮囊,心电监护示波
With the rapid development of medical electronic engineering, the pacemaker’s varieties and functions are increasing constantly. If it is not familiar with its performance in advance, it will be easily misjudged as “fault” in some special conditions. We have encountered two kinds of pacemaker installation “fake frequency unrestrained,” the report below, for reference. Example 1, Wu, male, 59 years old, the cause of suspected viral myocarditis, 3 ° atrioventricular block, placed in September 1991 ERGOS 02 buried DDDR frequency response pacemaker, nominal pacemaker Frequency of 72 beats / min. When the catheter is fixed, the pacemaker into the bladder, ECG monitoring oscilloscope
