Abstract
We report a case of a 55 year-old man with a history of vasovagal syncope who experienced six unexpected syncopal events
over the course of two hours. Two of these occurred in the supine position during ECG monitoring, which showed
a long-lasting sinus pause. Before the last syncopal episode, the ECG recording was started at the moment when the patient
had the recurrence of presyncopal symptoms. Recordings showed sinus rhythm slowing for 12 s and then sinus arrest lasting
for 29 s. A thorough clinical examination revealed no relevant abnormalities. The patient was treated with a permanent
pacemaker implantation.
