Syncope triggered by atrial flutter in a patient with a pacemaker: cross-stimulation-a case report.

ABSTRACT:

Background

Syncope in a patient with a pacemaker is a serious event requiring urgent action to ascertain its cause. Around 5% of cases are due to a pacemaker system malfunction.

Case summary

An 82-year-old man underwent dual-chamber permanent pacemaker implantation due to intermittent high-degree atrioventricular block (AVB) in sinus rhythm. Nine months later, the patient reported episodes of syncope. The chest X-ray showed both leads to be at their expected positions. The electrocardiography (ECG) showed common atrial flutter. Ventricular capture during pacing in atrial demand pacing (AAI) mode confirmed cross-stimulation due to the switching of the atrial and ventricular leads at the pacemaker header.

Discussion

Cross-stimulation is a rare possibility in a different
