Key result
Cardiac output estimation using the pulse time reflection ratio from ECG and PPG strongly correlated with impedance cardiography (mean r=0.88) with percent errors below the 30% clinical limit.

Effect estimate: mean r 0.88
A novel non-invasive method using ECG and PPG can accurately estimate beat-to-beat cardiac output during incremental exercise in healthy subjects.
Wang et al. (2010) studied Healthy (n=19). Pulse time reflection ratio (PTRR) from ECG and PPG vs. Impedance cardiography was evaluated on Correlation and estimation error of cardiac output (mean r 0.88). Cardiac output estimation using the pulse time reflection ratio from ECG and PPG strongly correlated with impedance cardiography (mean r=0.88) with percent errors below the 30% clinical limit.
