Abstract:
1. A method of assessing heart failure status in a patient, comprising: measuring a current inter-ventricular cardiac conduction time (IVCT); comparing the measured current IVCT to one of a programmable threshold IVCT and a previously measured IVCT; and responsive to the current IVCT differing from said one of the previously measured IVCT and the threshold IVCT, performing one of: detecting myocardial ischemia, wherein detecting myocardial ischemia includes: comparing a rate of change of the detected inter-ventricular cardiac conduction time to a range of change of inter-ventricular cardiac conduction times; and indicating a possible change in cardiac status when the detected inter-ventricular cardiac conduction time exceeds the threshold inter-ventricular cardiac conduction time and the rate of change of the detected inter-ventricular cardiac conduction time is within the rate of change.
