How does heart rate impact pulmonary RC time and right ventricular load?
Increased heart rate raises the pulsatile and total load on the right ventricle, providing a hemodynamic mechanism for the adverse effects of tachycardia.
Heart rate and BSA are associated with pulmonary RC time. As heart rate increases, the pulsatile and total load on the RV also increase. This relationship supports a hemodynamic mechanism for adverse effects of tachycardia on the RV.
Metkus et al. (2016) studied this question.
