Successful Treatment of Pallid Breath-Holding Spells With Fluoxetine

Abstract

Pallid breath-holding (PBH) is a childhood condition that presents with recurrent syncope. Although typically benign, severe cases can lead to asystole and anoxic seizures. Previous studies have advocated pacemaker placement to abbreviate symptoms. This was a retrospective study of patients treated with fluoxetine for PBH spells. Clinical response, side effects and avoidance of pacemaker implantation were reviewed in six patients (12–60 months) treated with fluoxetine for PBH. Patients were referred because of concern of arrhythmia and failed medical treatment strategies. Two patients had previously implanted loop recorders, 5 patients had documented episodes of asystole, and 2 patients had generalized seizures. Fluoxetine resulted in alleviation of syncope in 5 of 6 patients. Time to symptomatic improvement symptoms ranged from 2 days to 1 month (median, 2 weeks). Median duration of treatment with fluoxetine was 12 months (12–24 months). One patient demonstrated no improvement and had a pacemaker implanted. There were no reported side effects to fluoxetine. Fluoxetine can be used to treat childhood PBH spells and may obviate the need for permanent pacing in a significant subset of this population. Considering its safe side-effect profile it is a worthwhile first-line agent to treat this disorder.
