Abstract
The present document discloses a solution for estimating blood pulse wave characteristics by using multiple measurement locations of a human body. According to an aspect, a method includes detecting, in a first measurement signal measured by a first heart activity sensor associated with a first location of a human body, a first occurrence of a blood pulse wave; detecting, in a second measurement signal measured by a second heart activity sensor from a second location of the human body different from the first location, a second occurrence of the blood pulse wave; estimating, on the basis of said detections synchronized to a common clock, time characteristics of the blood pulse wave; and computing, on the basis of said time characteristics, a metric representing a physiological condition of the human body.
