Key result
VVI pacemaker resolves recurrent cough syncope in a case of sick sinus syndrome.
Why the study?
The mechanism of cough syncope in patients with sick sinus syndrome is not well understood.
Case Report (n=1)
Sinus arrest may be a mechanism of cough syncope in patients with sick sinus syndrome, which can be effectively treated with pacemaker implantation.
May support pacing consideration in refractory cough syncope with sinus arrest; leaves open generalizability and requires prospective confirmation.
Cough syncope is a syndrome in which dizziness or syncope occurs after prolonged bouts of cough. This paper presents a case of 63-year-old man with recurrent dizziness and syncope. The 24-hour ambulatory electrocardiogram and intracardiac electrogram showed sinus node dysfunction with sinus arrest, both spontaneous and inducible by voluntary cough. Sinus arrest was sometimes associated with dizziness. A permanent VVI pacemaker was implanted and no further cough syncope has occurred. We suggest that sinus arrest may play a role as a mechanism of cough syncope in a patient with sick sinus syndrome.

Choi et al. (1989) conducted a case report in Cough syncope and sick sinus syndrome (n=1). Permanent VVI pacemaker was evaluated on Recurrence of cough syncope. Implantation of a permanent VVI pacemaker prevented further episodes of cough syncope in a 63-year-old man with sick sinus syndrome and sinus arrest.
