21例室性心动过速(简称室速)者均为我院心内科住院病人,男14例、女7例,年龄13～70(38±21.1)岁。病因诊断:冠心病12例(急性心肌梗塞9例、不稳定型心绞痛3例),病毒性心肌炎6例,风湿性心脏病2例,肾肿瘤致低血钾1例。有3例患者心动过速发作时,心室率150～230次/分,R—R间隔匀齐,QRS波群间期0.12秒。记录食管导联心电图发现P波与QRS波群无关,确诊为室速。
Twenty-one cases of ventricular tachycardia (referred ventricular tachycardia) were hospitalized patients in our department of cardiology, 14 males and 7 females, aged 13 to 70 years (38 ± 21.1 years). Etiological diagnosis: Coronary heart disease in 12 cases (acute myocardial infarction in 9 cases, 3 cases of unstable angina), viral myocarditis in 6 cases, rheumatic heart disease in 2 cases, renal tumor caused by hypokalemia in 1 case. In 3 patients with tachycardia, the ventricular rate was 150 to 230 beats / min, the R-R intervals were uniform and the interval between QRS complexes was 0.12 seconds. Record esophageal lead ECG found that P wave and QRS wave group has nothing to do, diagnosed as VT.
