One or more left ventricle anatomical landmarks are identified on the 3D model, and saved views of the 3D model are registered on an interventional system. One or more of the registered saved views are visualized with the interventional system, and at least one suitable region on the left ventricle wall is identified for epicardial lead placement.

Abstract: A method for acquiring a cardiac image from a patient having a paced heart rhythm, an abnormal EKG, or an irregular heartbeat, is disclosed. A gated electrocardiogram signal having local maxima and minima values and trigger points is received. For a period of time, the time between each trigger point and the associated local maxima or minima is determined. In response to the trigger point occurring at the associated local maxima or minima, a zero time differential for a corrected trigger for gating is calculated, and in response to the trigger point not occurring at the associated local maxima or minima, a time differential for the corrected trigger for gating based on the time difference between the trigger point and the associated local maxima or minima is calculated.

Abstract: A method of displaying a representation of a physiological signal produced by a patient. The method includes the acts of obtaining a portion of at least one physiological signal acquired from the patient, determining an area to display, and constructing a virtual image representing at least a portion of the patient.
