室性早搏(室早)既可为生理性又可为病理性,明确诊断至关重要,因为这关系到处理及预后;对飞行员来讲正确诊断涉及继续飞行或停止飞行的问题。本文对冠心病90例及健康人80例(均合并室早)进行对比分析。认为35岁以上,室早属Lown氏Ⅲ级以上,或来源于左室的室早,或有双臂对称的倒置T波,室早 Premature ventricular contractions (ventricular premature beats) can be both physiological and pathological, a clear diagnosis is crucial, because it is related to the handling and prognosis; the correct diagnosis for the pilot involves the issue of continuing or stopping the flight. In this paper, 90 cases of coronary heart disease and healthy people in 80 cases (both combined early) for comparative analysis. That over the age of 35, the room was earlier than Lown’s Ⅲ or above, or from the left ventricular premature ventricular contractions or symmetrical T waves, early
