Prone positioning under spinal anesthesia warrants vigilance for vagal AV block; this case report leaves open the need for prospective confirmation.

Assuming a prone position under spinal anesthesia can trigger severe vagally mediated AV block leading to prolonged ventricular asystole and syncope.
Kim et al. (2016) conducted a case report in Vagally mediated atrioventricular block with ventricular asystole (n=1). Prone position under spinal anesthesia was evaluated on Development of AV block with ventricular asystole. Assuming a prone position under spinal anesthesia induced a severe vagally mediated atrioventricular block with prolonged ventricular asystole and syncope, which completely resolved upon returning to a supine position.
