Why the study?
Patients with OSA are at increased risk of cardiovascular morbidity and mortality driven largely by sympathetic overactivity, highlighting the need to review contemporary understandings and newer technologies for HRV analysis.
This review highlights the utility of heart rate variability and emerging technologies in assessing autonomic shifts and cardiovascular risk in patients with obstructive sleep apnea.
No takes yet. Share an insight, caveat, or question.
HRV may refine autonomic and cardiovascular risk assessment in OSA; leaves open prospective validation before routine clinical integration.
