多种原因可引起QT间期延长,而QT间期延长又常导致严重的室性心律失常,故受到临床上的重视。我院从1976年元月至82年11月,心电图发现有阵发性室性心动过速的内科住院患者共61例,现对其中具有室速发作前及发作时心电图对照的29例患者进行回顾性分析,以探讨QT间期延长对预测阵发性室性心动过速发作的价值。对象与方法一、一般情况:29例患者中,男18例,女n例,年龄17、79岁.基本病因为:风湿性心瓣膜病(xl例),冠心病(4例),心肌病(3例),心肌炎(3例),肺心病(2例),低钾(1例),高血压心脏病(1例),其他4例。导致室速发作的直接诱因:低血钾7例,洋地黄中毒4例,抗心律失常药(奎尼丁、普鲁卡因酸胺)3例,
A variety of reasons can cause prolonged QT interval, and QT prolongation often leads to serious ventricular arrhythmia, it is clinically valued. Our hospital from January 1976 to November 2002, electrocardiogram found in patients with paroxysmal ventricular tachycardia a total of 61 cases of inpatients, now with the onset of ventricular tachycardia and electrocardiographic control 29 patients were To retrospectively analyze the value of QT prolongation in predicting the onset of paroxysmal ventricular tachycardia. Subjects and methods First, the general situation: 29 patients, 18 males and n females, aged 17,79 years.The basic causes are: rheumatic valvular disease (xl cases), coronary heart disease (4 cases), cardiomyopathy (3 cases), myocarditis (3 cases), cor pulmonale (2 cases), hypokalemia (1 case), hypertensive heart disease (1 case) and other 4 cases. The direct cause of ventricular tachycardia: hypokalemia in 7 cases, digitalis poisoning in 4 cases, anti-arrhythmic drugs (quinidine, procaine amines) in 3 cases,
