Abstract
A system and methods for automatically adjusting view angle when performing cardiac mapping and ablation are described herein. A three-dimensional (3D) map of a cardiac structure of a patient and a relative location (e.g., position and orientation) of a catheter within the cardiac structure may be displayed on a visual display device. According to an example procedure, the position and orientation of the tip of the catheter within the cardiac structure, and the current ablation target may be detected. A desired viewing angle of the ablation target may be known, determined, provided and/or learned through training sessions with the operator. The viewing angle of the 3D map of the cardiac structure may be automatically adjusted to correspond to the desired viewing angle using the known locations of the tip of the catheter and ablation target. Other details and procedures may be implemented, as described herein.
