Heart analysis method and apparatus

摘要

A method and device for monitoring heart behavior. In particular, a visual aid for clinician in which regions of the heart having aberrant characteristics can be displayed. A number of electrodes are positioned near/on an endocardium; electrical signals from the electrodes are monitored and recorded. A variability of a time varying parameter is calculated from each electrode location and displayed on a cardiac image. A user can select the parameter and measurement properties of the parameter, wherein the variability of the parameter is displayed and aberrant behavior can be detected.

1. A method of identifying cardiac regions having aberrant conductive properties including steps of:
measuring a plurality of electrical signals from an endocardium wherein the measuring includes a time sequence; recording positions of each electrical signal; calculating a time varying parameter from the measured time sequence of electrical signals; computing a time-series variability of the time varying parameter over a selected duration from said electrical signals to thereby monitor the temporal variability of the time varying parameter which represents the continuous variation of an instantaneous value of the time varying parameter; and displaying said time-series variability at said positions on a cardiac image.
