不适当的电击仍然是植入型心律转复除颤器(ICD)使用的主要问题之一。我们描述了3例由于对横隔肌电位感觉过度而导致不适当电击的患者。总而言之，过度感觉可以在深吸气或瓦尔萨尔瓦动作中表现出来。其中一例通过在右室流出道置入单独的心率感应导线，第二例通过降低ICD的抗心动过缓起搏频率，第三例通过降低ICD的敏感性。我们认为，在ICD植入时应考虑到感觉性横隔肌电位的可能性，以便采取适当的预防措施。
Inappropriate shocks remain one of the major problems associated with the use of implantable cardioverter defibrillators (ICD). We describe 3 patients who had inappropriate shocks due to oversensing of diaphragmatic myopotentials. In all 3, oversensing could be demonstrated during deep inspiration or Valsalva maneuver. The problem was remedied in one by insertion of a separate rate sensing lead in the right ventricular outflow tract, in the second by decreasing the rate of antibradycardia pacing of the ICD, and in the third by decreasing the sensitivity of the ICD. We conclude that the possibility of sensed diaphragmatic myopotentials should be considered at the time of ICD implant so that appropriate preventive measures can be taken.
