Night Terrors as Prodromal Symptom of Obstructive Sleep Apnoea-Induced Arrhythmia: A Case Report.

We report a patient experiencing episodes of night terrors who, after 24-h ECG monitoring and polysomnography, was diagnosed with obstructive sleep apnoea-induced atrioventricular block. His symptoms resolved following continuous positive airway pressure therapy. This case may indicate that night terrors can be an atypical manifestation of hypopnoea or arrhythmia. Therefore, it may be reasonable for physicians to conduct appropriate screening and diagnostic tests to diagnose underlying treatable diseases like obstructive sleep apnoea in individuals presenting with suggestive symptoms.
