摘要
目的应用24h动态心电图检查探讨室性心动过速发生的特点及临床意义。方法回顾性分析动态心电图检查出的室性心动过速患者90例图形资料。结果90例患者中动态心电图共检测出室性心动过速1203次,室性心动过速发作室率为73~250次/min其中24h内发生一阵室性心动过速的69例(76.6%)。78例基础心率为窦性心律(86.6%)。单源性室速73例(81.1%),多源性室速17例(18.9%)。室速发生时有头晕心悸胸闷气短等86例(95.5%)。90例患者中同时伴有sT—T改变者79例(87.7%)。90例患者87例为非持续性室速,3例为持续性室性心动过速,均为自行终止。随访中5例死亡,3例为心肌缺血发生室颤而猝死。结论室速的发生与器质性心脏病合并高血压、心肌缺血、心力衰竭、心律不齐、电解质紊乱等密切相关,及时去除病因,积极治疗原发病,大多数室速均可转好。
Objective To analyze the charactgeristics and clinical significance of ventricular tachycardia (VT). Methods Dynaimc electromyocardiography (DEG) was used to record the 24-h ECG of 1920 randomly selected in-patients. The clinical data thus collected of 90 patients with VT, 68 males and 22 females, aged 77.3 (46-96), 62 with coronary heart diseases, 13 with hypertensive heart disease, 8 with hypokalemia. 2 with rheumatic heart disease, 1 with dilated cardiomyophathy, 1 with uremis, 4 with cerebrovescular diseasea, 4 with pulmonary heart diseases, and 5 with unknown caauses, were analyzed by computer. Results 1203 times of VT were detected with the ventricular rates of 73-250 times/min. 69 cases (76.6%) were recorded with only one episode of VT during 24h. The basic ventricular rhythm of 78 cases (86.6%) was sinusoid rhythm. Unifocal VT was seen in 73 cases (81.1), and muhifocal VT in 17 cases (18.9%). Symptoms of diziness, palpitation, breast distress, and short berath occurred during VT attack in 86 cases (95.5%). ST-T changes were seen in 79 cases (87.7%). The VT was non-pertinent in 87 cases, and pertinent in 3 cases. The VT automatically terminated in all patients. 3 patients died during the follow-up, 3 of which died of ventricular fibrillation caused by myocardial ischemia. Conclusion VT is associated with heart disesses complicated with hypertension, nyocardial ischemia, hypokalemia, etc.
