Key result
PVC prevalence reaches ~61% in healthy adults and rises significantly with advancing age.
Why the study?
The prevalence and characteristics of premature ventricular beats in healthy adults aged 20 to 79 years were not well described.

PVBs are common and age-related in healthy adults; leaves open their prognostic relevance without longitudinal data.
Cross-Sectional (n=111)
What is the prevalence and frequency of premature ventricular beats in healthy adults aged 20 to 79 years?
p-value: p=<0.05
Premature ventricular beats are common in healthy adults and their prevalence increases significantly with age, though the vast majority have fewer than 300 PVBs per 24 hours.
Rasmussen et al. (1985) conducted a cross-sectional in Healthy (n=111). Age vs. Younger age groups was evaluated on Prevalence of one or more premature ventricular beats (PVBs) (p=<0.05). In healthy adults, the prevalence of premature ventricular beats on 24-hour ECG was 61%, increasing significantly with age from 31% in subjects aged 20-39 to 84% in those aged 60-79 (P<0.05).
