SUMMARY 1. Ambulatory ECG monitoring was undertaken in healthy cigarette smokers (33) and non‐smokers (20) of similar age (21–66 years). 2. The frequency of ventricular premature complexes (VPC) was less in habitual smokers ( P < 0,05; Mann‐Whitney rank test) and an average of more than 1 VPC per hour occurred in a higher proportion of non‐smokers than smokers: eight of 20 (40%) vs two of 33 (6%) ( P < 0.01; Chi‐square test).
