Key result
Respiratory rates derived from Heart Rate Variability and Peak Amplitude Variation methods were compared and validated against original respiration signals in normal and pulmonary disease subjects.
Why the study?
Can respiratory rate be accurately estimated from single-lead ECG using HRV and PAV methods compared to original respiration signals?
Can respiratory rate be accurately estimated from single-lead ECG using HRV and PAV methods compared to original respiration signals?
ECG-derived respiration using HRV and PAV methods offers a potentially unobtrusive way to monitor respiratory rates in ambulatory and ICU patients.
Supports feasibility of ECG-derived respiration in pulmonary disease; leaves open larger validation before clinical adoption.
The necessity of respiratory monitoring is rapidly increasing in medical field to diagnose various cardio-pulmonary diseases. It is difficult to monitor respiration for ambulatory and ICU patients, as conventional methods are either obtrusive or suffer from low accuracy. The extraction of ECG derived respiration (EDR) signal using single-lead ECG has been proposed lately. This allows monitoring of ECG and respiration signal simultaneously from a recorded ECG signal. Recently few methods for EDR extraction from ECG are reported in literature. In this work, respiratory rates (RR) are derived from Heart Rate Variability (HRV) and Peak Amplitude Variation (PAV) method and a comparative study of these two methods is reported. Moreover, the validation of the proposed methods is made by comparing the obtained RR with that derived from original respiration signal. Subjects from Fantasia database and real-time data for both normal and with pulmonary diseases are considered for the work.

Sarkar et al. (2015) studied Normal and pulmonary diseases. Heart Rate Variability (HRV) and Peak Amplitude Variation (PAV) methods vs. Original respiration signal was evaluated on Respiratory rates (RR) derived from ECG. Respiratory rates derived from Heart Rate Variability and Peak Amplitude Variation methods were compared and validated against original respiration signals in normal and pulmonary disease subjects.
