【摘要】 为探讨室性早搏(室早)的临床意义,本文分析我院自1973年3月至1983年2月,10年间心电图诊断室性早搏者共473例.其中有器质性心脏病及低血钾297例,无器质性心脏病176冽.结果显示在器质性心脏病心电图上除室早外,心电图异常发生率高.室早来自双室或左室、室早波幅低支持器质性心脏病.室早呈QR型反映心肌梗塞.室早RonT或RonP均可诱发室速.早搏指数<0.9应警惕,易发生室速.室早后T波改变多见于器质性心脏病.更多还原

【Abstract】 In order to demonstrate the clinical significance of premature ventric-ular beats, we analyed 473 cases of premature ventricular beats with electrocardiogram from March 1973 to February 1983. Among them were 297 cases of organic lesion of heart and hypokalcmia and 176 cases with no features of heart disease. Besides ectopic beats, a high incidence of abnormal electrocardiogram was found in association with the organic heart disease. The ectopic beats arising from either left ventricle, or low amplitude or even both, might indicate patients have organic heart disease. QR-type might show myocardial infartion. "R on T" or "R on P" phenomenon may be responsible for the initiation of ventricular tachycardia. The prematurity index shows that 0.9 would be considered hazardous because it is eary to produce ventricular tacycardia. A change on T-wave after premature ventricular beat is often a suggestive of an organic lesion in heart.更多还原
