摘  要:本文探讨急性心肌梗塞后心室晚电位与程序电刺激诱发持续性室性心动过速、心室纤颤的关系。17只犬心肌梗塞后3~5天,13只体表记录到心室晚电位,其中12只诱发了持续性室性心动过速或/和心室纤颤(94.11%,P<0.01)。结果提示:心室晚电位的出现与程序电刺激诱发持续性室性心动过速、心室纤颤有明显相关性。Seventeen dogs were used for the detection of ventricular late potentials (LPs) on body surfaceand programmed electrical stimulation (PES) before and after myocardial infarction (MI) 3-5 days.The correlation between LPs and sustained ventricular tachycardia (SVT), ventricular fibrillation (VF)induced by PES were analysed. LPs appeared in 13 dogs (13/17, 76.47%), and SVT/VF were inducedin 12 dogs that LPs were positive (12/13, 94.11%, P<0.01) after MI. The results suggest that thereis high correlation between LPs and SVT/VF induced by PES. LPs may serve as a significant indexfor predicting the risk after MI.
