一、急性心脏疾患并发的室性早搏(VPC) 1.急性心肌梗塞(AMI) AMI急性期出现的VPC很快会产生室颤(VF)～持续型室速(SVT)。目前的CCU系统多是从如何早期发现VPC来研究的。如想把AMI的急性期院内死亡率从35～40%降至10～15%,就要重视此期VPC的严重性。因此,对这种VPC,通常需要紧急治疗。作者报告AMI(发病6小时以内)住院的262名患者中,有20名出现原发性VF,并研究了在VF发生前记录到的心律失常种类,诱发VF的VPC联律间距(QR/QT)等,但警报性VPC的发生率仅仅60%,而全部心肌梗塞患者中警报性VPC的发生率是59%,两者没有差别。关于R_onT型VPC,20例中11例QR/QT≥
First, acute heart disease complicated by premature ventricular contractions (VPC) 1. Acute myocardial infarction (AMI) AMI AMI appear acute acute ventricular fibrillation (VF) ~ sustained ventricular tachycardia (SVT). The current CCU system is mostly from how to detect VPC early to study. To reduce the acute in-hospital mortality rate of AMI from 35 to 40% to 10 to 15%, we must pay attention to the severity of VPC in this period. Therefore, emergency treatment is usually required for such VPCs. The authors report that 20 of 262 patients hospitalized with AMI (within 6 hours of onset) developed primary VF and studied the types of arrhythmias documented before VF onset, VPC association spacing induced by VF (QR / QT ), Etc. However, the incidence of alarming VPC was only 60% and the incidence of alarming VPC in all MI patients was 59%. There was no difference between the two. About R_onT VPC, 11 cases of QR / QT ≥ 20 cases
