36. A method of monitoring signals form an implantable medical device that provides a stimulus to a patient comprising:
-
detecting a radio frequency artifact from implantable medical device; and
processing the radio frequency artifact from the implantable medical device in order to determine where artifact occurs in an ECG and identify heartbeats that are paced and heartbeats that are paced and heartbeats that are not paced and occurrences of pacing that fail to stimulate a heart beat. - View Dependent Claims (37, 38, 39, 40, 41)
