Key result
Latent coronary heart disease in middle-aged men was associated with a shorter PR interval compared to normal men, whereas advanced stable clinical CHD rarely caused prolonged PR at rest.

Challenges assumption that stable CHD prolongs PR interval; hypothesis-generating for shorter PR in latent disease detection.
Observational (n=2,666)
Advanced stable clinical coronary heart disease rarely causes prolonged PR at rest, and subjects with latent CHD may actually have shorter PR intervals than healthy counterparts.
Erikssen et al. (1982) conducted an observational in Coronary heart disease (n=2,666). Coronary heart disease (overt and latent) vs. Normal men without coronary heart disease was evaluated on PR interval duration. Latent coronary heart disease in middle-aged men was associated with a shorter PR interval compared to normal men, whereas advanced stable clinical CHD rarely caused prolonged PR at rest.
