First degree AV block epidemiology and demographics
Introduction
Overview
Overview
The prevalence of First-degree AV block is approximately 1000-2000 per 100,000 individuals in developed countries. The incidence of First-degree AV block was estimated to be 1000 cases per 100,000 in children and adolescent athletes and significantly lower than adults due to lower vagal tone in children. First-degree AV block is more commonly observed among elderly patients. Men are more commonly affected with first-degree AV block than women. The male to female ratio is approximately 2 to 1. First-degree AV block was more commonly observed among African-American subjects compared with Caucasian subjects.
