Abstract
Devices and methods for detecting events indicative of heart failure (HF) decompensation status are described. An ambulatory medical device can determine the present physiologic state as being either a drift state or a stable state, and applies an algorithm to detect HF decompensation event according to the physiologic state. In some embodiments, the ambulatory medical device uses the present physiologic state to estimate one ore more expected future signal characteristics, and to detect HF decompensation event using the one or more expected futures signal characteristics.
