High-grade second-degree atrioventricular block associated with obstructive sleep apnea syndrome (experience in the effective use of respiratory support)

Sleep-disordered breathing and nighttime bradyarrhythmias associated with this syndrome are often encountered in clinical practice. With high-grade atrioventricular blocks, such patients are usually implanted with a permanent pacemaker, but this treatment method is not indicated for patients with reversible conduction disorders. A clinical case of the successful use of CPAP therapy in a patient with second degree atrioventricular block at night associated with obstructive sleep apnea syndrome is presented. Approaches to the diagnosis and treatment of patients with bradyarrhythmias are discussed.
