摘要：
In specific embodiments, a method for estimating central arterial blood pressure (CBP), comprises determining a time t1 from a predetermined feature of a signal indicative of electrical activity to a predetermined feature of one of a first and second signals, the time t1 being a first pulse arrival time (PAT1) indicative of how long it takes a pulse wave to travel from the aorta to one of a first and second sites, determining a time t2, the time t2 being a second pulse arrival time (PAT2) indicative of how long it takes a pulse wave to travel from the aorta to the other of the first and second sites, and (f) estimating the patient's central arterial blood pressure (CBP) based on the first pulse arrival time (PAT1) and the second pulse arrival time (PAT2).
