Abstract
An implantable activity detector can detect metabolic stress levels, which can be normalized, such as to identify times of activities such as walking and running or to identify trends such as a decrease in metabolic activity. The data can be derived from different sources such as an accelerometer and pedometer. This data can be compared to independently specifiable thresholds, such as to trigger an alert or responsive therapy, or to display one or more trends. The information can also be combined with other congestive heart failure (CHF) indications. The alert can notify the patient or a caregiver, such as via remote monitoring. Metabolic activity data from one or more of the activity detectors can be used to establish a model of metabolic stress, to which further activity data can be compared for identifying periods of increased or decreased metabolic stress.
