Analysis and use of cardiographic bioimpedance measurements
First Claim
1. A computer program product, tangibly embodied on computer-readable media, the computer program product being operable to cause a data processing apparatus to:
- receive bioimpedance information of a subject;
determine a rate of change of blood flow based on the bioimpedance information;
determine if the rate of change of blood flow includes at least two peaks during the systole of the subject;
if the rate of change of blood flow includes at least two peaks, determine a time based on at least one of the two peaks; and
compare the determined time to a threshold time.

Abstract
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.

12. A method for using cardiographic measurements of a subject having a cardio cycle, the cardio cycle comprising a systole, the method comprising:
-
determining a rate of change of blood flow; determining if the rate of change of blood flow has at least two peaks during the systole of the subject; if there are at least two peaks, determining a time difference based on at least one of the two peaks; comparing the determining time to a threshold time; if the determining time is greater than the threshold time, implanting a pacemaker in the subject; and if the determining time is not greater than the threshold time, not implanting a pacemaker in the subject. - View Dependent Claims (13, 14, 15, 16, 17, 18)
