System And Method For Automated Diagnosis Of Myocardial Ischemia Through Remote Monitoring
First Claim
1. A system for automated diagnosis of myocardial ischemia through remote monitoring, comprising:
- a database module storing physiological measures comprising data either recorded on a regular basis by a medical device or derived therefrom;
a comparison module matching qualitative measures associated with the physiological measures;
an analysis module remotely identifying indications of myocardial ischemia, by examining the qualitative measures for both of a reduction in exercise capacity and respiratory distress occurring contemporaneously, and evaluating the qualitative measures for angina that accompanies the reduction in exercise capacity and the respiratory distress; and
a diagnostic module determining a time course for each of the indications, and forming a patient status comprising an onset of myocardial ischemia conditioned on the time course comprising a short duration.

Abstract
A system and method for automated diagnosis of myocardial ischemia through remote monitoring is described. Physiological measures comprising data either recorded on a regular basis by a medical device or derived therefrom is stored. Qualitative measures associated with the physiological measures are matched. Indications of myocardial ischemia are remotely identified. The qualitative measures for both of a reduction in exercise capacity and respiratory distress occurring contemporaneously are examined. The qualitative measures for angina that accompanies the reduction in exercise capacity and the respiratory distress are evaluated. A time course for each of the indications is determined. A patient status is formed comprising an onset of myocardial ischemia conditioned on the time course comprising a short duration.
