Does a patch-type HRV analyzer with AI analysis improve the detection of obstructive sleep apnea compared to demographic and previous ECG-based screening?
A patch-type HRV analyzer with AI analysis provides accurate, low-interference screening for obstructive sleep apnea, outperforming traditional demographic and ECG-based methods.
Background: , may reduce sleep quality and have limited accuracy. Methods: and simultaneous overnight monitoring with a patch-type heart rate variability (HRV) analyzer. After strict data quality control, 86 subjects remained. HRV indices from ECG signals were processed using time-, frequency-, and nonlinear-domain analyses. An artificial intelligence (AI) model, incorporating a novel Cardiovascular Hypopnea Index (CVHI), was developed using leave-one-out validation. Results: The AI model achieved 81.4% accuracy, outperforming demographic-based (73%) and previous ECG-based (70.6%) screening. At an apnea-hypopnea index (AHI) cutoff of 15, it showed strong classification for moderate-to-severe OSA (AUC >0.8). Conclusion: The patch-type HRV analyzer with AI analysis provides accurate, low-interference OSA screening, suitable for large-scale clinical and home use.
