Abstract:
An implantable cardiac device is configured and programmed to assess a patient's cardiopulmonary function by evaluating the patient's heart rate response. Such evaluation may be performed by computing a heart rate response slope, defined as the ratio of an incremental change in intrinsic heart rate to an incremental change in measured activity level. The heart rate response slope may then be compared with a normal range to assess the patient's functional status.
