Key result
Permanent pacemakers demonstrate ~64% three-year survival, substantially exceeding historical unpaced rates.

Does permanent pacemaker implantation improve survival in patients with AV block or disturbed consciousness compared to historical unpaced survival?
Permanent pacemaker implantation provides substantial survival benefits for patients with AV block and disturbed consciousness, achieving a 64% survival rate at three years.
Sven Åke Forsberg (1978) conducted a cohort in AV block and disturbed consciousness (n=140). Permanent pacemaker treatment vs. Historical unpaced survival was evaluated on Survival at 3 years. Permanent pacemaker treatment resulted in survival rates of 86%, 73%, and 64% at 1, 2, and 3 years, respectively, demonstrating substantial benefit compared to historical unpaced survival.
