室性心动过速(VT)和心室颤动(VF)是心脏性猝死的主要原因。近年研究VT、VF的发生与心室晚电位(VLP)有关,其临床价值已成为目前心脏病学的一个新课题。一、VLP的成因及定义 80年代初,欧美学者进行了VLP研究,Breithardl在动物实验性心肌梗塞部直接标测,记录到心室舒张早期有多个钉状碎裂的电活动,并发现 Ventricular tachycardia (VT) and ventricular fibrillation (VF) are the major causes of sudden cardiac death. In recent years, the study of VT, VF and the occurrence of ventricular late potential (VLP), its clinical value has become a new topic in cardiology. First, the cause of VLP and definition In the early 1980s, European and American scholars conducted a VLP study, Breithardl in the animal experimental myocardial infarction directly mapping, recorded early ventricular diastolic spike fragmentation of the electrical activity and found
