ICG and dorsoventral SCG ensemble averaged traces (n = 5 heartbeats) obtained with the sensor on the sternum for three different subjects. The ICG B-points and SCG AO-points are marked with red circles, and there is a substantial time difference between the two corresponding points for the three subjects: in two cases the ICG B-point occurs first, and in the third case the SCG AO-point occurs first.
