过去十年闾,心脏病学家们对于猝死已经积累了大量资料,然而在许多方面尚未完全明嘹。猝死者大多原有心脏病变和严重心律失常。筛选高危病人、阐明猝死机制和采取预防措施亟待解决。一、猝死的预报因子动态心电图监测和电生理测试是筛选猝死高危病人的主要方法。作者试析这些方法的价值。 (一)电生理测试心肌梗塞后进行电生理测试,15%~50%病人可诱发快速室性心律失常,持续性和非持续性室速各作半数左右。四组研究结果表明,心室电不稳性同猝死或室速显著相关;而另外七组则否。各组病例数、病例选择的标准、随访时间、用药情况,特别是电生理测试的时机均不相同。凡 In the past ten years, cardiologists have accumulated a great deal of information about sudden death, yet in many aspects they have not yet fully understood. Most of the sudden death of patients with heart disease and severe arrhythmia. Screening high-risk patients, elucidating the mechanism of sudden death and taking precautions need to be resolved. A sudden death predictors Holter monitoring and electrophysiological testing is the screening of high-risk patients with sudden death of the main methods. The author tries to analyze the value of these methods. (A) electrophysiological test electrophysiological test after myocardial infarction, 15% to 50% of patients can induce rapid ventricular arrhythmia, sustained and non-sustained ventricular rate for each of about half. The results of the four groups of studies show that ventricular electrical instability is significantly associated with sudden death or VT, while the other seven groups are not. The number of cases in each group, the criteria for case selection, follow-up time, medication, especially the timing of electrophysiological tests are not the same. Where
