Magnusdottir S, Hilmisson H. Ambulatory screening tool for sleep apnea: analyzing a single-lead electrocardiogram (ECG). Sleep Breath 2017; 22(2): 421- 429. DOI: 10.1007/s11325-017/-1566-6
The goal was to determine the utility and accuracy of automated analysis of single-lead electrocardiogram (ECG) data using two algorithms, cardiopulmonary coupling (CPC), and cyclic variation of heart rate (CVHR) to identify sleep apnea (SA).
The CPC-CVHR technology performed as accurately to identify patients with moderate to severe SA.
The CPC-CVHR (SleepImage) method is a clinically powerful tool that can be implemented in various clinical settings to identify patients at risk for SA.
