A young man suffered cardiac arrests with polymorphic ventricular tachycardia (PVT) and ventricular fibrillation (VF) triggered by ventricular premature contractions (PVCs). The arrhythmia was resistant to anti-arrhythmics, so after ICD implantation he underwent successful ablation of the triggering VE beat, which was pace-mapped to the left posterior hemi-fascicle. We review the evidence for the role of the Purkinje network in the initiation and maintenance of PVT and VF, postulating a channelopathy as a possible underlying cause, and provide recommendations for PVC ablation.
一名年轻男性因室性早搏(PVC)引发多形性室性心动过速(PVT)和心室颤动(VF)而发生心脏骤停。心律失常对抗心律失常药物耐药,因此在植入植入式心脏复律除颤器(ICD)后,他成功消融了触发室性早搏,该早搏经起搏标测定位于左后半分支。我们回顾了浦肯野网络在PVT和VF起始及维持中作用的证据,推测通道病可能是潜在病因,并提供了PVC消融的建议。
