CARDIAC MONITORING SYSTEM

摘要

A method of analysing cardiac function in a subject using a processing system. The method includes causing one or more electrical signals to be applied [100] to the subject using a first set of electrodes, the one or more electrical signals having a plurality of frequencies. The method includes determining an indication of electrical signals [110] measured across a second set of electrodes applied to the subject in response to the applied one or more signals. Following this and for a number of sequential time instances, the method includes determining from the indicating data and the one or more applied signals, an instantaneous impedance values [120] at each of the plurality of frequencies and determining using the instantaneous impedance values an intracellular impedance parameter [130]. The intracellular impedance parameter over at least one cardiac cycle is used to determine one or more parameters relating to cardiac function [150].
