摘要

一名七旬老人因完全性心脏传导阻滞接受了双腔起搏器（DDDR - 美国马萨诸塞州波士顿科学公司）植入手术。术中导联参数在正常范围内。即使在术前心电图（ECG）上也发现了频繁的多源性室性早搏。在随访心电图上，第一个搏动的 QRS 上出现一个起搏尖峰，随后 T 波上出现两个起搏尖峰，第一个复律的整个 QRST 上总共出现三个起搏尖峰。其机制是什么？

Triple pacing spikes on QRST: What is the mechanism?

A septuagenarian man underwent dual chamber pacemaker (DDDR - Boston Scientific Massachusetts, U.S.) insertion for a complete heart block. Intra-procedural lead parameters were within normal limits. Frequent multisite origin premature ventricular complexes were noted even on pre-procedural electrocardiogram (ECG). On the follow-up ECG one pacing spike on the QRS of the first beat was followed by two pacing spikes on the T wave with a total of three pacing spikes on the whole QRST of the first complex. What is the mechanism?

期刊介绍： The Journal of Electrocardiology is devoted exclusively to clinical and experimental studies of the electrical activities of the heart. It seeks to contribute significantly to the accuracy of diagnosis and prognosis and the effective treatment, prevention, or delay of heart disease. Editorial contents include electrocardiography, vectorcardiography, arrhythmias, membrane action potential, cardiac pacing, monitoring defibrillation, instrumentation, drug effects, and computer applications.
