Does noninvasive radial tonometry accurately derive central blood pressure during exercise compared to invasive measurement in patients undergoing coronary angiography?
Radial tonometry and pulse wave analysis provide an accurate noninvasive estimation of central blood pressure at rest and during exercise.
Sharman et al. (2006) studied this question.
