Overview
Bradycardia is mostly the result of sinus node dysfunction found in one in 600 individuals over 65 years of age. There is no racial predilection for bradycardia and it affects all genders equally.
Epidemiology and Demographics
Incidence
- The incidence of bradycardia is approximately 1 in 600 individuals worldwide.[1]
Prevalence
- The prevalence of unexplained sinus bradycardia (SB) is approximately 400 per 100,000 individuals worldwide.[2]
- The frequency of sick sinus syndrome is unknown in the general population, while in cardiac patients it has been estimated to be 3 in 5000.
Age
- Bradycardia is more common in older patients, over the age of 65 years.
Race
- There is no racial predilection to bradycardia.
Gender
- Bradycardia affects men and women equally.[3]
