345例短阵性室速患者的检测和临床分析

目的：探讨Holter对短阵室速与年龄、病因、发作时段及其伴随的其他改变的关系。方法：回顾性分析1996年10月～2003年6月共345例短阵室速发作时的Holter检测。结果：345例短阵室速(PVT)患的Holtel。检测中，无心脏病(60例)，随年龄增长发病率似有下降趋势；有明确器质性心脏病(285例)，其发病率随年龄增长而增加；心脏病人中以冠心病发生率为高(占52．3％)，其中陈旧性心肌梗死(陈旧性心梗)患最多(占76．5％)；285例短阵性室速患中有ST—T缺血性改变的99例，其中冠心病80例，陈旧性心梗56例；短阵性室速的发作时段以上午6点至12点为最高。结论：285例短阵性室速发作随年龄增长而增多，60岁以上的心脏病人发生率更多，高达58．6％；短阵室速及伴有ST—T缺血改变，以冠心病发病率为高，必须针对室速作用时段使用抗心律失常药物，以收事半功倍之效。

Clinic analysis of 345 cases with paroxysmal ventricular tachycardia

Objective: Analysis the correlation among between paroxysmal ventricular tachycardia and ages, the cause of disease,period of episode. Methods: Retrospectively analysis the Holter data of 345 paroxysmal ventricular tachycardia (PVT) cases from Oct 1996 to Jun 2003. Results: In Holter data of 345 PVT cases, the morbidity in non-heart disease cases (60 cases) was tended to decrease with increase of age, but in heart disease cases (285 cases) it was tended to increase. Most of patient with heart disease was coronary heart disease (CHD, 52.3%). in which old myocardial infarction (OMI) account for 76. 5% ; There were 99 cases with the change of ST-T in 285 PVT cases, in which CHD account for 80 cases, OMI was 56 cases; the most period of episode was in 6 Am-12 Am. Conclusion: The episode of PVT is increase accompany age enhance. The PVT morbidity of more than 60 years old patients was 58. 6%. The morbidity of coronary heart disease especially OMI were highest in patients with PVT and patients with changes of ischemia ST-T. We should according to the period of episode to use antiarrhythmic.
