心室晚电位(VLP)是一种无创伤性检查新技术,在临床常常用来筛选和预测是否可能发生室速或室颤.本文根据20例急性心肌梗塞(AMI)病人和20例正常人 VLP 测定的资料,分析和探讨其临床意义.一般资料1.病例选择 AMI 组20例,男15例,女5例,年龄45～80岁。正常组20例,男女各10例,年龄40～60岁。病程:AMI 组20例均在1个月内。2.选用仪器采用 ART-1200型心室晚电位仪,进行体表心室晚电位测定。噪声<0.4μv,叠加次数>200次。3.诊断标准诊断标准 VLP 尚未完全一致,一般具备下列一项即可考虑为 VL(?)阳性:①VLP时限>10ms。②总 Q R S 时限>120ms.③QRS40<25μv。临床资料
Ventricular late potential (VLP) is a new noninvasive technique used in clinic to screen and predict whether ventricular tachycardia or ventricular fibrillation may occur.According to 20 patients with acute myocardial infarction (AMI) and 20 normal subjects Analysis and explore the clinical significance of general information 1. Case Selection AMI group of 20 patients, 15 males and 5 females, aged 45 to 80 years. Normal group of 20 patients, 10 males and 10 females, aged 40 to 60 years. Course of disease: AMI group, 20 cases were within 1 month. 2. Selection of instruments used ART-1200 ventricular late potentiometer, the body surface ventricular late potentiometry. Noise <0.4μv, stacking times> 200 times. 3. Diagnostic criteria Diagnostic criteria VLP has not been completely consistent, generally have one of the following can be considered as VL (?) Positive: ① VLP time limit> 10ms. ② total Q R S time limit> 120ms.QQS40 <25μv. clinical information
