Atropine administration during dobutamine stress echocardiography can rarely cause vagally mediated transient complete AV block and ventricular asystole.

Atropine may provoke asystole in ESRD during dobutamine stress testing; single case leaves open safety questions in renal failure.
Dobutamine stress echocardiography is a safe diagnostic test with low incidence of serious complications. Atropine has been shown to reduce test duration without increasing the rate of complications. We present a case of a 52-year-old man with end stage renal disease who experienced syncope due to ventricular asystole after atropine administration during a dobutamine stress test. The underlying pathophysiology is discussed.

Buda et al. (2020) conducted a case report in End stage renal disease, undergoing dobutamine stress echocardiography (n=1). Atropine was evaluated on Ventricular asystole. Administration of atropine during a dobutamine stress test in a 52-year-old man resulted in transient third-degree heart block and ventricular asystole.
