A Heart Rhythm Society Annual Scientific Sessions abstract found that a sensor featured in implantable cardioverter defibrillators provided comparable data to diagnose patients with sleep apnea and to improve management compared with polysomnography, reports Healio.

In the prospective study, polysomnography scoring was completed blinded to the implantable impedance respiration sensor (ApneaScan, Boston Scientific). Researchers defined severe sleep apnea as an apnea-hypopnea index of at least 30 events per hour.
