文氏现象(周期)最常见于二度房室传导阻滞,传导系统其它部位产生文氏现象的机会较少(1),而室早折返通路文氏现象更为少见,虽然文氏周期多连续依次重复出现,但室早折返通路中文氏现象多间歇性出现(2),现结合典型病例报告如下.典型病例ECG分析例1,患者,男,55岁,临床诊断为冠心,ECG示:窦性加异位节律,具有频发室早,肢体导联低电压,心肌损伤等心电图改变,特殊的是在V_3、V_4导联中(图1),除异位心动间只扦有一个窦性心动者外,室 Wen’s phenomenon (cycle) is most common in second-degree atrioventricular block, there is less chance of Venn happening in other parts of the conduction system (1), and Ventricular phenomenon of ventricular premature reentry pass is more rare, (2), are combined with the typical case report is as follows Typical cases of ECG analysis 1, the patient, male, 55 years old, the clinical diagnosis of coronary heart disease, ECG showed : Sinus plus ectopic rhythm, with frequent room early, low limb lead leads, myocardial damage and other ECG changes, especially in the V_3, V_4 lead (Figure 1), except the ectopic heart only one skew Sinus outside, room
