Single-lead ECG based autonomic nervous system assessment for meditation monitoring.

Scientific Reports December 29, 2022 Chanki Park, Inchan Youn, Sungmin Han

We propose a single-lead ECG-based heart rate variability (HRV) analysis algorithm to quantify autonomic nervous system activity during meditation. Respiratory sinus arrhythmia (RSA) induced by breathing is a dominant component of HRV, but its frequency depends on an individual's breathing speed. To address this RSA issue, we designed a novel HRV tachogram decomposition algorithm and new HRV...
