In a cardiac stimulation method, device and system, a capture verification condition is determined. For this purpose, a number of pacing pulses are delivered to a heart chamber and signals are sensed within a time window following each pacing pulse. The sensed signals are stored and categorized as representing capture or non-capture. Using the stored signals, a weight vector is determined, that assigns different weights for different parts of each sensed signal within the time window. The weight vector is used for calculating a weighted area within the time window. The capture verification condition is determined by identifying whether the weighted area, calculated with the weight vector, of a sensed signal within the time window is above or below a predetermined value.
