Methods and systems for monitoring heart rate recovery are described. In
one embodiment, an implantable monitoring device monitors a patient's heart activity.
The monitor looks for periods of increased activity, such as those that are experienced
during some level of exercise, and periods of lesser activity (such as rest) directly
following. The patient's heart rate recovery is monitored as the heart recovers
from the active period to the rest period. Data associated with the patient's heart
rate recovery can then be diagnostically used to ascertain certain conditions associated
with the patient.
