摘要：A method of analysing cardiac functions in a subject using a processing system isdescribed. The method may include applying one or more electrical signals having aplurality of frequencies to the subject and detecting a response to the applied one ormore signals from the subject. A characteristic frequency can then be determined fromthe applied and received signals, and at least one component of the impedance (e.g.,reactance, phase shift) can be measured at the characteristic frequency. Thus, the

impedance or a component of impedance at a characteristic frequency can be determinedfor a number of sequential time instances. A new characteristic frequency may bedetermined within a cardiac cycle (e.g., with each sequential time instant) or the samecharacteristic frequency may be used throughout the cardiac cycle during whichinstantaneous values of impedance (or a component of impedance) are determined.These instantaneous values may be used to 'determine one or more indicia of cardiacfunction.
