System and method of monitoring physiological signals
First Claim
1. A physiological signal monitoring and analysis system comprising:
- an implantable medical device configured to monitor and record sample segments of at least one physiological signal of a patient at time separated recording intervals over a time period; and
a signal processor configured to measure values of at least one selected characteristic of the at least one physiological signal from the recorded sample segments, to determine trend information representing a trend in the at least one selected characteristic based on the measured values, and to assess a risk of a physiological event to the patient based on the trend information.

Abstract
A physiological signal monitoring and analysis system including an implantable medical device and a signal processor. The implantable medical device is configured to monitor and record sample segments of at least one physiological signal of a patient at time separated recording intervals over a time period. The signal processor configured to measure values of at least one selected characteristic of the at least one physiological signal from the recorded sample segments, to determine trend information representing a trend in the at least one selected characteristic based on the measured values, and to assess a risk of a physiological event to the patient based on the trend information.

23. A method of monitoring and analyzing at least one physiological signal of a patient, the method comprising:
-
recording sample segments of at least one physiological signal of a patient at time separated recording intervals over a time period using a medical device implanted within the patient;
measuring values of at least one selected characteristic of the at least one physiological signal from the recorded sample segments;
determining trend information representing a trend in the at least one selected characteristic based on the measured values; and
assessing a risk to the patient of a physiological event based on the trend information. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)

57. A method of assessing the risk of a patient for sudden cardiac death, the method comprising:
-
recording sample segments of an electrocardiogram signal of the patient at time separated recording intervals over a time period using an implantable medical device implanted within the patient;
measuring values of at least one selected characteristic of the electrocardiogram signal from the recorded sample segments;
determining trend information representing a trend in the at least one selected characteristic based on the measured values; and
