Periodic breathing is an abnormal oscillatory ventilation pattern consisting of cyclic hyperpnea and hypopnea, which can occur in heart failure (HF) patients during sleep or on exertion.
Corra and associates assessed the prognostic value of sleep periodic breathing and exertional periodic breathing in a prospective study of 133 patients with stable, moderate to severe HF as a result of ischemic or idiopathic dilated cardiomyopathy (Circulation 2006;113:44-50).
A total of 67 patients (50%) had some form of periodic breathing: 39 patients (29%) had severe sleep periodic breathing alone, 6 (4%) had exertional periodic breathing alone, and 22 (16%) had both.
