A 57-year-old man with idiopathic ventricular tachycardia (VT) underwent electrophysiological testing. Activation mapping revealed two remote earliest ventricular activation sites on anterior and posterior sides of the anterior papillary muscle. On the anterior side, far-field activity preceded near-field activity. Catheter ablation was successful on the posterior side. Ventricular far-field activity may provide diagnostic challenges in identifying papillary muscle VT origins.
一位 57 岁男性患有特发性室性心动过速（VT），接受了电生理测试。激活图显示前乳头肌前侧和后侧有两个远程最早心室激活部位。在前侧，远场活动先于近场活动。后侧导管消融成功。心室远场活动可能在确定乳头肌 VT 起源方面带来诊断挑战。
