Key result
A 58-year-old man who suffered out-of-hospital cardiac arrest due to a complete atrioventricular block induced by coronary artery spasm was successfully treated with optimal medical therapy and permanent pacemaker implantation.
Case Report (n=1)
Coronary artery spasm can rarely cause complete atrioventricular block leading to cardiac arrest, which may require permanent pacemaker implantation to prevent recurrence.
Answers are grounded in this paper and cite their sources.
Rare spasm-induced AV block causing arrest may require pacing; hypothesis-generating and should not change practice pending larger studies.

Sato et al. (2013) conducted a case report in Out-of-hospital cardiac arrest, complete atrioventricular block, coronary artery spasm (n=1). Permanent pacemaker implantation and optimal medical therapy was evaluated. A 58-year-old man who suffered out-of-hospital cardiac arrest due to a complete atrioventricular block induced by coronary artery spasm was successfully treated with optimal medical therapy and permanent pacemaker implantation.
