Junctional bradycardia epidemiology and demographics

Junctional bradycardia is fairly uncommon. It can occur in any age group, however it is more likely to be observed in elderly people with underlying heart disease.

Junctional bradycardia occurs in normal children and adults, particularly during sleep when rates may transiently drop as low as of 30 beats per minute and pauses of up to 2 seconds are not uncommon. Benign junctional rhythms are common in both children and athletic young adults.

Males and females are affected equally.
