Results of cryoenergy and ra-diofrequency- based catheter ab-lation for treating ventricular ar-rhythmias arising from the papil-lary muscles of the left ventricle, guided by intracardiac echocar-diography and image integration

         

摘要

室性期前搏动室性期前搏动(PVC)常见于伴或不伴结构性心脏疾病(SHD)患者,有患者:PVC频发而无症状,另有患者症状明显而异位搏动较少。多个研究证实频发.PVC与潜在可逆性的心肌病之间存在关联,所选患者心肌病在导管消融后消失。已报道与左心室功能障碍相关的24h PCV数即负荷值通常达到总心搏数的15%~25%以上,尽管可低达10%。然而,鉴于PVC可为心肌病的结果 ,因此。
