Claim:
1. An injectable device for use in subcutaneous physiological monitoring of a patient, the injectable device comprising: a body; a plurality of sensors that provide an indication of at least one physiological event of a patient, wherein the plurality of sensors include current delivery electrodes and sensing electrodes in contact with tissue of the patient and spaced along the body of the injectable device; and a monitoring unit located within the body and coupled to the plurality of sensors and configured to monitor a bioimpedance of the patient using the current delivery electrodes and sensing electrodes, wherein the monitoring unit utilizes the monitored bioimpedance to determine a hydration of surrounding tissue and wherein the monitoring unit is further configured to, based at least in part on the determined hydration, detect an impending cardiac decompensation of the patient.
