摘要

Changes in physiologic parameters may be detected in a patient by measuring the impedance of a tissue segment located in a selected electrode vector field, storing baseline impedance information based on the measured impedance, detecting changes in impedance characteristics from the baseline impedance information, and providing alerts for changes in the physiologic parameters based on the detected changes in impedance characteristics. In some situations, detecting the changes in impedance characteristics involves detecting changes in morphology of an impedance waveform, such as a cardiac component of an impedance waveform, a respiratory component of an impedance waveform, and the phase angle of the complex impedance.
