ANALYSIS AND USE OF IMPEDANCE CARDIOGRAPHIC MEASUREMENTS

摘要

A technique for analyzing cardiography measurements is described, in particular to detect inter- and intraventicular asynchronism. The technique includes receiving bioimpedance information of a subject; determining a rate of change of blood flow based on the bioimpedance information; determining 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 difference based on at least one of the two of the peaks; and compare the determined time to a threshold time. The comparison may be used to decide on implanting a pacemaker in the subject, or to make adjustments to an implanted pacemaker.
