Routine electrocardiographic tracings (ECGs) were obtained from 491 male and 236 female Norwegians. The atrioventricular conduction time (P‐R interval) was read independently on coded ECGs by two physicians. The frequency distributions are presented: mean ± 2 SD was 0.16 ± 0.04 s and 0.15 ± 0.04 s for males and females, respectively. Intra‐individual repeatability over 1 year was high, and the measurement error was small. Within each sex, body size, age, heart rate and non‐cardiac disease manifestations had little influence on the P‐R interval. The P‐R interval may be reliably determined in routine ECG tracinge by trained observers.
