111 healthy subjects, 57 males and 54 females, 20-79 years of age, randomly selected among the participants of the Copenhagen City Heart Study were tested for ventricular ectopic activity using ambulatory 24-h ECG recording. One or more premature ventricular beats (PVBs) appeared in 68 subjects (61%), 35 males and 33 females (61% of each group). The prevalence of PVBs increased significantly with age: 31, 68 and 84% in the respective age groups: 20-39, 40-59 and 60-79 (P less than 0.05). The number of PVBs per 24 h was less than 24 in 88 (79%), less than 300 in 105 (95%), and less than 500 in 107 (96%). More than 1000 PVBs per 24 h appeared in 3 (2.7%), one of whom had 11 669. The number of PVBs per 24 h increased with age, but the increase was not statistically significant. The number of PVBs per 100 000 recorded QRS-complexes did not differ significantly from the number of PVBs per 24 h. The number of PVBs h-1 was highest in daytime, and apparently higher in males than in females. However, the difference between the two sexes was not statistically significant. Multiform PVBs appeared in 4 subjects, interpolated PVBs in 2, a run of 5 PVBs in 1, dropped beats in 3, two pauses of 1900 ms duration in 1, and several post-acceleration pauses of 1300 ms duration in 1.
从哥本哈根市心脏研究的参与者中随机选取了111名健康受试者，年龄在20至79岁之间，其中男性57名，女性54名，采用24小时动态心电图记录对其室性异位活动进行检测。68名受试者（61%）出现一个或多个室性早搏（PVB），其中男性35名，女性33名（每组均为61%）。PVB的患病率随年龄显著增加：在20 - 39岁、40 - 59岁和60 - 79岁年龄组中分别为31%、68%和84%（P小于0.05）。每24小时PVB的数量，88名受试者（79%）少于24次，105名受试者（95%）少于300次，107名受试者（96%）少于500次。每24小时超过1000次PVB的有3名受试者（2.7%），其中1名有11669次。每24小时PVB的数量随年龄增加，但增加无统计学意义。每100000次记录的QRS波群中PVB的数量与每24小时PVB的数量无显著差异。每小时PVB的数量白天最高，且男性明显高于女性。然而，两性之间的差异无统计学意义。4名受试者出现多形性PVB，2名出现插入性PVB，1名出现连续5次PVB，3名出现漏搏，1名出现2次持续1900毫秒的停搏，1名出现几次持续1300毫秒的加速后停搏。
