起搏故障临床表现为:起搏脉冲停止或间断、间歇起搏、脉冲频率改变、丧失按需功能等。其原因在于:①起搏器元件失灵或线路障碍;②电极导线断裂、短路;③接头插件接触不良;④电极移位;⑤阈值升高;⑥电池耗竭等。发生起搏故障时应仔细检查、分析原因,及时排除故障,保证安全有效之起搏。一般应先询问病史了解心功能状态、应用起搏器的历史情况、起搏器的种类等,进行体检听心率、数脉搏,观察心率与起搏器指示频率是否一致,对起搏故障范围作一大略估计,然后检查起搏器及放置部位、检查电极导线插件及导线
Clinical manifestations of pacing failure: pacing pulse stop or intermittent, intermittent pacing, pulse frequency changes, loss of on-demand functions. The reason is that: ① pacemaker components failure or line obstacles; ② electrode wire breakage, short circuit; ③ connector plug poor contact; ④ electrode displacement; ⑤ threshold value; ⑥ battery depletion and so on. Pace to occur when the fault should be carefully checked, analyze the reasons for the timely troubleshooting, to ensure safe and effective pacing. General should first ask the history to understand the state of cardiac function, the application of pacemaker history, the type of pacemaker, physical examination to listen to heart rate, the number of pulses, observe the pacemaker and pacemaker instructions frequency is consistent, the range of pacing failure A rough estimate, and then check the pacemaker and place, check the electrode lead plug and wire
