Does a multiple regression method using pulse arrival time, heart rate, and arterial stiffness improve blood pressure estimation accuracy compared to pulse arrival time alone?
Incorporating heart rate and arterial stiffness alongside pulse arrival time improves the accuracy of non-invasive, non-intrusive blood pressure estimation.
Baek et al. (2009) studied Blood pressure estimation. Multiple regression using pulse arrival time, heart rate, and arterial stiffness vs. Methods considering pulse arrival time only was evaluated on Correlation between measured and estimated blood pressure. A multiple-regression method incorporating pulse arrival time, heart rate, and arterial stiffness improved blood pressure estimation correlation compared to methods using pulse arrival time alone.
