"The decay of aortic blood pressure during diastole: Influence of an asymptotic pressure level on the exponential fit";
Artery Research, 8 (2014), 4; S. 162 - 163.

Kurzfassung englisch:
Aortic blood pressure is decreasing approximately exponentially during
diastole and the time constant of the decay is supposed to hold information about total arterial compliance and peripheral resistance. However, it is unclear if the pressure would drop to zero without further excitations from the heart or if it would reach an asymptotic pressure level Pinf. The aim of this work was to examine the fitting performance of an exponential decay with and without Pinf in invasive aortic pressure readings with prolonged diastoles caused by missing heartbeats.
