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.
To investigate the clinical significance of premature ventricular contractions (premature ventricular contractions) in our hospital from March 1973 to February 1983, ECG analysis of pre-ectricensive patients in a total of 473 cases, including organic heart disease and low blood 297 cases of potassium, no organic heart disease 176 冽 .The results showed that in patients with organic heart disease ECG on the exception of the early, the high incidence of abnormal electrocardiogram. Room early from the double room or left ventricular, early ventricular low support quality Ventricular premature QR-type reflects myocardial infarction.As early RonT or RonP can induce VT.Early index <0.9 should be vigilant, prone to ventricular tachycardia .T room changes in T wave more common in organic heart disease.
