1. A system for determining a maximum observed heart rate, said system comprising:
- a heart rate monitor;
an activity level monitor; and
a processor responsive to heart rate measurements from the heart rate monitor and activity level measurements from the activity level monitor, and configured to identify a heart rate as the maximum observed heart rate when the following conditions occur;
(i) the activity level exceeds an activity threshold, (ii) a heart rate measurement is greater than a stored heart rate measurement, and (iii) a difference between the heart rate measurement and the stored heart rate measurement does not exceed a predetermined threshold.

Abstract
A device, such as an implantable cardiac device, and methods for determining exercise diagnostic parameters of a patient are disclosed. Specifically, a maximum observed heart rate of a patient during exercise can be identified when an activity level and a heart rate measurement of the patient exceed predetermined thresholds. Included are methods for filtering out premature heartbeats or noise from the maximum heart rate determination. Methods of determining other exercise parameters, such as workload are also disclosed. The device includes hardware and/or software for performing the described methods.
