After entrainment pacing, the postpacing interval of a diastolic potential may be misinterpreted if the distal tip of the ablation catheter captures a remote bystander pathway adjacent to the critical isthmus of a complex reentrant circuit in a structurally diseased heart. We discuss this possible pitfall of entrainment mapping of reentrant ventricular tachycardia, observed after a healed myocardial infarction.
在超速起搏后,如果消融导管的远端电极在结构异常的心脏中捕获了与复杂折返环关键峡部相邻的远距离旁观者通道,舒张期电位的起搏后间期可能会被误判。我们讨论了在心肌梗死愈合后观察到的折返性室性心动过速超速标测中这一可能的陷阱。
