我们采用心室晚电位(VLP)预测折返性、室性阵发性心动过速与心室颤动取得了满意的效果。经40例临床预测,证明它是一种无创伤检查新技术,值得推广应用。临床资料选择急性心肌梗塞(AMI)组20例,男15例,女5例,年龄45～80岁。大多数有剧烈胸痛,病程均在1个月内。对照组20例,男女各10例,年龄40～60岁,无心脏病表现。心脏 X 线照片、超声心动图、心电图及24时动态心电图均属正常。采用 ABT-1200型心室晚电位仪,进行体表心室晚电位测定。一般有下列一项即可考虑为 VLP 阳性:①VLP 时限>40ms;②总 QRS 时限>120ms;③QRS40<250uv。测试结果
We used ventricular late potentials (VLP) to predict reentry, ventricular paroxysmal tachycardia and ventricular fibrillation achieved satisfactory results. After 40 cases of clinical prediction, it is a non-invasive examination of new technologies, it is worth to promote the application. Clinical data of 20 patients with acute myocardial infarction (AMI) group, 15 males and 5 females, aged 45 to 80 years. Most have severe chest pain, duration are within 1 month. Control group of 20 patients, 10 men and women, aged 40 to 60 years, no heart disease performance. Cardiac X-ray, echocardiography, ECG and 24-hour Holter are normal. Using ABT-1200 ventricular late potentiometer, the body surface ventricular late potentiometry. Generally one of the following can be considered VLP positive: ① VLP time limit> 40ms; ② total QRS time limit> 120ms; ③ QRS40 <250uv. Test Results
