室性早搏(简称室早)是临床最常见的一种心律失常。可见于各种心脏病病人、非心脏病病人及各种年龄健康无病的人群。室早的心电图特点1.频发性室早:每分钟多于5～10次的室早称为频发性室早,多认为是器质性的。甚至有人把每分钟多于10次的频发性室早与三束支阻滞、高度或完全房室传导阻滞、严重病窦、室性心动过速(室速)、多源性室早及 RonT、RonP 现象一齐列为易转为致死性心律失常的重症心律失常。郑氏12例室颤 Premature ventricular contractions (referred to as room early) is the most common clinical arrhythmia. Can be found in a variety of heart disease patients, non-heart disease patients and various age-free healthy people. Early ECG characteristics of room 1. Frequent room early: more than 5 to 10 times per minute as early room frequent room, and more that is organic. Someone even more than 10 times per minute frequent premature ventricular contractions with three bundle branch block, a high degree or complete atrioventricular block, severe sick sinus, ventricular tachycardia (VT), multi-source early And RonT, RonP phenomenon together as a fatal arrhythmia can be converted to severe arrhythmia.
