Cardiac Arrhythmia and Conduction Disturbances on Patients with Obstructive Sleep Apnea: Clinical Implications and Technical Solution

EasyChair Preprint no. 3571

Abstract

Background: Obstructive sleep apnea (OSA) or sleep-disordered breathing (SDB) were commonly seen among patients with cardiac rhythm disorders, and OSA is then presumed to operate as triggers cardiac arrhythmias and conduction disorders (ACDs). In OSA, the drop of peripheral oxygen saturation (SpO2) over a few seconds as a result of an apnea or hypopneaevents making the SpO2 an OSA screening parameter. Despite the potential link between OSA and ACDs have been suggested and discussed for long, there has scarcely been reports. Methodology: The study describes the possible association of some significant ACDs and OSA in patients hospitalized for cardiovascular and/or pulmonary disorders, and in those who had been presumed to have cardiorespiratory disorders and passed the specialized examination in hospital outpatient department. Respiratory or cardiorespiratory polygraphy (rPG/crPG) was performed when appropriate divided patients into with OSA and without OSA subgroups. The 24-hour ambulatory ECG was done thereafter to identify ACDs on both with- and without OSA subgroups. Results: Of total 48 patients, the current study showed in the subgroup of 26 patients with OSA a more prevalent presence of ACDs including premature atrial complexes, sinus bradycardia, sinus pauses, premature ventricular complexes and paroxysmal atrial fibrillation,compared to otherwise similar subgroup of 22 patients without OSA. Conclusion and Discussion: The possible association should be further assessed by the indication of ambulatory ECG recording and that of crPG on subjects with or suspected of cardiorepiratory disorders and/or SDB. By looking for technical solution allowing concurrent use of crPG and ambulatory ECG recording, the efforts to have crPG and ECG recording or, to lesser extent, certain relevant parameters/channels of these integrated in a common command unit might be medically sound, engineeringly feasible and cost-effective.
