Obstructive sleep apnea as a potentially reversible cause of nighttime bradyarrhythmias. Clinical case

Obstructive sleep apnea syndrome is a common condition, especially among obese patients. Patients with obstructive sleep apnea syndrome have an increased risk of developing arterial hypertension and cardiovascular events, as well as cardiac arrhythmias, which include reflexively occurring bradyarrhythmias and episodes of asystole at night. Treatment of obstructive sleep apnea syndrome leads to an improvement in the patient’s quality of life and also reduces cardiovascular risk and eliminates associated bradyarrhythmias during night sleep.
