Abstract:
1. An implantable monitoring device comprising: one or more processors; one or more sensors operably coupled with the one or more processors and configured to sense a patient's heart beat; and memory coupled to the one or more processors, wherein the memory stores instructions which, when executed by the one or more processors, cause the one or more processors to: determine a patients heart rate from heart beats sensed by the one or more sensors; detect an active period associated with a patient's physical exertion and characterized by an elevated heart rate; detect termination of the active period as characterized by a heart rate that is slower than the elevated heart rate; monitor the patient's heart rate recovery as the patient's heart recovers from a generally elevated rate associated with the active period, to a slower rate that is not associated with the active period; and ascertain whether the monitored heart rate recovery is normal for that patient.
