室性期前收缩(简称室早)为临床上常见的心律失常,它可见于正常人,也可见于心脏病人,也可发生于代谢紊乱的情况下。因此,临床医师对其都应有一个充分的认识。1室早的心电图表现室早的心电图表现为:①提前出现宽大畸形的QRS群,其前无相关P波,QRS波群时间>0.12秒,T波与QRS主波方向相反,ST段随T波方向而移位。②代偿间期完全。③联律间期固定。
Ventricular premature contraction (referred to as room early) clinically common arrhythmias, it can be found in normal subjects, but also in patients with heart disease, metabolic disorders can also occur in the circumstances. Therefore, clinicians should have a full understanding of it. Early ventricular ECG showed room early ECG showed: ① premature emergence of large deformity QRS group, the former without related P wave, QRS wave group time> 0.12 seconds, T wave and QRS main wave in the opposite direction, ST segment with T Wave direction and shift. ② compensatory interval is complete. ③ joint law between the fixed.
