Key result
Transvenous cardiac pacing successfully resolves complete ventricular asystole complicating complete heart block.
Why the study?
Patients with recurrent syncope are at risk for underlying conduction disease that may worsen if not promptly recognized and treated.
Case Report (n=1)
Supports feasibility of transvenous pacing in acute asystole; single case leaves open need for prospective validation.
Patients who present with recurrent syncope are at risk for having underlying conduction disease, which may worsen if not promptly recognized and treated. We describe a patient who initially presented to a Mexican clinic with recurrent syncope and an electrocardiogram that showed complete heart block. After being transferred to our emergency department, he deteriorated into complete ventricular asystole with preserved atrial function and required placement of a transvenous cardiac pacemaker.

Zanoni et al. (2014) conducted a case report in Syncope and altered mental status due to complete ventricular asystole (n=1). Transcutaneous and transvenous cardiac pacing was evaluated. A 68-year-old male with recurrent syncope and complete heart block deteriorated into complete ventricular asystole and was successfully treated with a transvenous cardiac pacemaker.
