Edhag et al. (1976) conducted an observational in Complete heart block or arrhythmic syncope (n=101). Complete heart block with Adams-Stokes attacks vs. Asymptomatic complete heart block was evaluated on Survival rate. Among unpaced patients with complete heart block, survival was 68% at 1 year and 37% at 5 years, with worse outcomes in those with Adams-Stokes attacks or coexisting cardiovascular conditions.
