    摘要: An exemplary method includes selecting multiple electrodes located in a patient; acquiring position information during one or more cardiac cycles for the multiple electrodes where the acquiring includes using each of the electrodes for measuring one or more electrical potentials in an electrical localization field established in the patient; calculating one or more vector metrics based on the acquired position information for one or more vectors, each vector defined by two of the multiple electrodes; and analyzing the one or more vector metrics to assess cardiac performance during the one or more cardiac cycles. Various other methods, devices, systems, etc., are also disclosed.

    摘要: A system and method are provided for monitoring ischemic development. The system and method identify a non-physiologic event and obtain cardiac signals along multiple sensing vectors, wherein at least a portion of the sensing vectors extend to or from electrodes located proximate to the left ventricle. The system and method monitor a segment of interest in the cardiac signals obtained along the multiple sensing vectors to identify deviations in the segment of interest from a baseline. The system and method record at least one of timing or segment shift information associated with the deviations in the segments of interest; and identify 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.
