IMPEDANCE MEASUREMENT TO MONITOR ORGAN PERFUSION OR HEMODYNAMIC STATUS
摘要
An implantable medical device system and associated method deliver drive signals having different frequencies to establish vector fields comprising an arterial volume and a venous volume corresponding to targeted portion of a patient's body. Impedance signals are determined in response to drive signals having different frequencies. Impedance parameter values are determined over time. A change in the hemodynamic status of a targeted portion of the patient's body is identified in response to the impedance parameter values.
