A technique for analyzing cardiographic measurements includes receiving bioimpedance information of a subject and determining a rate of change of blood flow based on the bioimpedance information. If the rate of change of blood flow includes at least two peaks during the systole of the subject, a time difference based on at least one of the two of the peaks is determined and compared to a threshold time. A technique for using the cardiographic measurements of the subject further includes if the determined time is greater than the threshold time, implanting a pacemaker in the subject and if the determined time is not greater than the threshold time, not implanting a pacemaker in the subject.
