May support deferring prophylactic pacing in asymptomatic patients; hypothesis-generating and requires validation in larger prospective cohorts.
Does prolonged sinoatrial conduction time predict significant bradyarrhythmic morbidity requiring prophylactic pacing?
Prolonged sinoatrial conduction time is associated with sinus node abnormalities but has low bradyarrhythmic morbidity, suggesting prophylactic pacing is not indicated in asymptomatic patients.
Dhingra et al. (1977) studied this question.
