    摘要： An apparatus for determining tissue versus fluid components of an organ include a detector that generates a detector signal based on electrical signals derived from tissue and fluid. The apparatus includes a signal processor in communication with the detector which subtracts in real time a tissue component from the detector signal and produces a fluid volume signal. A method for monitoring a patient's fluid volume of a patient's organ. An apparatus for monitoring a patient's organ. A method for monitoring a patient's organ. A method to piggyback an admittance system onto a AICD/Bi-ventricular Pacemaker for a heart of a patient, in particular a weakened heart having features consistent with congestive heart failure. An apparatus for monitoring an organ, such as a heart, lungs, brain, skeletal muscle, and bladder of a patient which includes a detector which detects the admittance of the organ. The apparatus includes a transmitter in communication with the detector which transmits a wireless signal indicative of the admittance of the organ. A method for monitoring an organ of a patient includes the steps of detecting with a detector the admittance of the organ. There is the step of transmitting with a transmitter in communication with the detector a wireless signal indicative of admittance of the organ.

    摘要： An apparatus for determining heart transplant rejection of a heart in a patient includes at least two electrodes adapted to be sewn into the heart that span the left ventricle. The apparatus includes a voltage generator adapted to be inserted in the patient which generates a voltage to the two electrodes and senses the resulting voltage from the two electrodes. A method for determining heart transplant rejection of a heart in a patient. A pacemaker for a patient (including bi-ventricular pacing and AICDs). The pacemaker includes an RV lead having four electrodes adapted to be inserted into the RV apex. The pacemaker includes a voltage generator which generates a voltage signal to the electrodes and senses the instantaneous voltage along the length of the RV and determines the real and imaginary components to remove the myocardial components of the septum and RV free wall to determine absolute RV blood volume. The pacemaker includes a battery connected to the voltage generator. The pacemaker includes a defibrillator connected to the battery. The pacemaker can also be a bi-ventricular pacemaker to restore RV and LV synchrony during contraction. A method for assisting a heart of a patient.
