Methods and systems to correlate arrhythmic and ischemic events
First Claim
1. A method for determining whether there is a correlation between arrhythmias and myocardial ischemic episodes experienced by a patient, comprising:
- using an implantable system to monitor for arrhythmias and to monitor for myocardial ischemic episodes;
storing, within the implantable system, data indicative of detected arrhythmias and data indicative of detected myocardial ischemic episodes;
communicating information regarding detected arrhythmias and detected myocardial ischemic episodes from the implantable system to an external device;
for each detected arrhythmia, determining, based on the data, whether there was a myocardial ischemic episode detected within a specified time before the arrhythmia; and
displaying on an external display an indicator that a detected arrhythmia and a detected myocardial ischemic episode occurred within the specified time of each other.

Abstract
Systems and methods for determining whether there is a correlation between arrhythmias and myocardial ischemic episodes are provided. An implantable system (e.g., a monitor, pacemaker or ICD) is used to monitor for arrhythmias and to monitor for myocardial ischemic episodes. When such events are detected by the implantable system, the implantable system stores (e.g., in its memory) data indicative of the detected arrhythmias and data indicative of the detected myocardial, ischemic episodes. Then, for each detected arrhythmia, a determination is made based on the data, whether there was a myocardial ischemic episode detected within a specified temporal proximity of (e.g., within a specified amount of time of) the arrhythmia. Where a myocardial ischemic episode occurred within the specified temporal proximity of an arrhythmia, data for the two events can be linked. Additionally, when a log of arrhythmias is displayed, for each arrhythmia there is an indication of whether a myocardial ischemic episode was detected within the specified temporal proximity of the arrhythmia. This abstract is not intended to be a complete description of, or limit the scope of, the invention.
