摘要：
A method and system are presented for use in assessment of at least one cardiac parameter of an individual. An electrodes arrangement is applied to an individuals body, for applying an electrical field to the body and providing an electrical output indicative of a systolic impedance change and of a velocity of said change during a cardiac cycle. Also provided is additional data indicative of at least of the following conditions of the individual: a value of total peripheral resistance (TPR), a value of cardiac index (CI), and existence of the AHF condition. Data corresponding to these condition is analyzed to determine whether the TPR satisfies a first predetermined condition and/or the CI satisfies a predetermined second condition and/or whether the acute heart failure (AHF) condition is identified, to thereby use the data indicative of the measured electrical output and selectively calculate said at least one cardiac parameter based on either the systolic impedance change data or on said data of the velocity of the impedance change.
