Supports SPAP-MPAP linearity in transplants and pacing; extends prior observations but leaves open broader validation.
Is the linear relationship between systolic and mean pulmonary arterial pressure maintained regardless of autonomic or rhythm disturbances?
The linear relationship between systolic and mean pulmonary arterial pressure is a passive consequence of the elastic properties of the cardiopulmonary unit, maintained across various autonomic and rhythm disturbances.
Eynden et al. (2016) studied this question.
