Patent ID: 8447389

Claim:
A method for monitoring ischemic development, comprising: implanting at least one implantable lead having at least one LV electrode Proximate to a left ventricle; identifying an abnormal sinus rhythm using the at least one implantable lead; obtaining cardiac signals along multiple sensing vectors, wherein at least a portion of the sensing vectors extend to or from the at least one LV electrode located proximate to the left ventricle; monitoring a segment of interest in the cardiac signals that occurred after the detection of the abnormal sinus rhythm, the cardiac signals being obtained along the multiple sensing vectors using a processor adapted to identify deviations in the segment of interest from a baseline; recording at least one of timing or segment shift information associated with the deviations in the segments of interest; and identifying at least one of size, direction of development or rate of progression of an ischemia region based on the at least one of timing or segment shift information.
