为明确无明显心脏病的成人室性早搏（PVC）的发生率、频率和特点，对101例（男51例，女50例，平均年龄48.8岁）体格检查、胸部X线、心电图、超声心动图、最大运动负荷试验、右心导管和左心导管及冠状动脉造影均正常的受试者进行了24小时动态心电图检查。受试者（39例）在任何给定的小时内至少有1次PVC/24 h，但4例PVC/24 h> 100，少于5例PVC> 5。具有至少1次PVC/24小时的概率随年龄增加而增加（χ 2 = 11.789，P = 0.019）。PVC/24 h数与年龄呈正相关（r = 0.33，P = 0.001）。PVC/24 h的存在或数量与性别、血压、体重、身高、体重指数、血清K或Ca、胆固醇和甘油三酯、Hb、摄入咖啡、茶或酒精以及吸烟之间没有一致的关系。4例受试者有多种形式的PVC，其中2例有早期PVC。
To define the prevalence, frequency and characteristics of premature ventricular complexes (PVC) in adults free of recognizable heart disease 24 h ambulatory ECG was performed on 101 subjects (51 men and 50 women, mean age 48.8 yr) in whom physical examination, chest X-ray, ECG, echocardiogram, maximal exercise stress test, right- and left-heart catheterization and coronary arteriography were normal. Subjects (39) had at least 1 PVC/24 h, but 4 had > 100 PVC/24 h and fewer than 5 had > 5 PVC in any given hour. The probability of having at least 1 PVC/24 h increased with age (.chi.2 = 11.789, P = 0.019). The number of PVC/24 h was positively associated with age (r = 0.33, P = 0.001). There was no consistent relationship between the presence or number of PVC/24 h and sex, blood pressure, weight, height, body mass index, serum K or Ca, cholesterol and triglyceride, Hb, the ingestion of coffee, tea or alcohol and cigarette smoking. Four subjects had multiform PVC 2 of whom had early PVC.
