并行心律属特殊的异位心律,多见于器质性心脏病,因而多数预后严重。本文综合32例心电图证实的室并行心律进行临床观察和随访。结果发现不同的室并行心律其临床经过和预后有明显差别,与文献报告不尽一致,因此对本病的正确认识和治疗都有一定的参考意义。临床资料:依据心电图观测,按并行心律的诊断标准把病人分为二组:即单灶性室并行心律(简称单室并行心律)20例(Ⅰ组),双重或多重性室并行心律(简称多重室并行心律)12例(Ⅱ组)。Ⅰ组:男12例。女8例,年龄20～78岁。经临床综合检查后,确诊冠心病2例,肺心病1例,心肌炎3例,原因不明者14例,无1例出现心功失偿者。心电图诊断依据可见一种相同形态的室性异位搏动,并具有并行收缩的特点(图 Parallel heart rhythm is a special ectopic heart rhythm, more common in organic heart disease, and most prognosis is serious. In this paper, 32 cases of ventricular cardiogram confirmed by ECG confirmed by clinical observation and follow-up. The results showed that different clinical ventricular rhythm and prognosis of significant differences, and the literature reports are not the same, so the correct understanding of the disease and treatment have some reference value. Clinical data: According to the ECG observation, the patients were divided into two groups according to the diagnostic criteria of the parallel heart rhythm: 20 cases (group Ⅰ) with single-chamber ventricular arrhythmia (group Ⅰ), double or multiple ventricular arrhythmias Multiple room parallel heart rate) in 12 cases (Ⅱ group). Group Ⅰ: 12 males. 8 females, aged 20 to 78 years old. After clinical comprehensive examination, diagnosed coronary heart disease in 2 cases, 1 case of cor pulmonale, myocarditis in 3 cases, 14 cases of unknown cause, no 1 cases of cardiac insufficiency. ECG diagnosis based on the same form of ventricular ectopic beating, and has the characteristics of parallel contraction (Figure
