Abstract
Systems and methods of detecting an impending cardiac decompensation of a patient measure at least two of an electrocardiogram signal of the patient, a hydration signal of the patient, a respiration signal of the patient or an activity signal of the patient. The at least two of the electrocardiogram signal, the hydration signal, the respiration signal or the activity signal are combined with an algorithm to detect the impending cardiac decompensation.

43. A system to predict impending acute cardiac decompensation of a patient, the system comprising:
-
an adherent patch including at least four electrodes connected to the patch and capable of electrically coupling to the patient; impedance circuitry coupled to two or more of the at least four electrodes to measure an impedance associated with the patient; a temperature sensor configured to measure a temperature of a skin of the patient; and a processor system in communication with the impedance circuitry and the temperature sensor, wherein the processor system calculates a hydration measurement based on the measured impedance and corrects the calculated hydration measurement based on the measured skin temperature of the patient, wherein the processor system utilizes the calculated hydration measurement to predict an impending acute cardiac decompensation of the patient. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53)

54. A system to predict an impending acute cardiac decompensation of a patient having heart failure, the system comprising:
-
an adherent device including at least four electrodes capable of electrically coupling to the patient; impedance circuitry coupled to two or more of the at least four electrodes to measure an impedance value associated with the patient and a respiration signal; electrocardiogram circuitry coupled to two or more of the at least four electrodes to measure an electrocardiogram signal associated with the patient; and a processor system in communication with the impedance circuitry and the electrocardiogram circuitry, wherein the processor system receives the impedance measurement, the respiration signal and the electrocardiogram signal and compares the received signals with baseline values established for each, wherein the processor sets a flag indicating an impending acute cardiac decompensation based on a combination of the compared values. - View Dependent Claims (55, 56, 57, 58, 59, 60, 61, 62)
