Methods of generating a graphical representation of cardiac information on a display screen are provided. The method comprises: electronically creating or acquiring an anatomical model of the heart including multiple cardiac locations; electronically determining a data set of source information corresponding to cardiac activity at the multiple cardiac locations; electronically rendering the data set of source information in relation to the multiple cardiac locations on the display screen. Systems and devices for providing a graphical representation of cardiac information are also provided.

Cardiac analysis user interface system and method

Disclosed are devices, systems, and methods for determining the dipole densities on a cardiac surface using a plurality of electrodes, including electrodes positioned on a torso of a patient.

Devices and methods for determination of electrical dipole densities on a cardiac surface

Provided herein are systems and methods for calculating patient information. The method includes determining a transfer matrix, recording electric potentials via a first set of recording electrodes located at a first set of recording locations to create a first set of recorded signals, and calculating patient information for a set of target locations by applying the transfer matrix to the first set of recorded signals. The transfer matrix is a characterization of electrical properties of tissue between the first set of recording locations and the set of target locations.

Systems and methods for calculating patient information

Disclosed are devices, systems, and methods for determining the dipole densities on heart walls. In particular, a triangularization of the heart wall is performed in which the dipole density of each of multiple regions correlate to the potential measured at various located within the associated chamber of the heart. To create a database of dipole densities, mapping information recorded by multiple electrodes located on one or more catheters and anatomical information is used. In addition, skin electrodes may be implemented. Additionally, one or more ultrasound elements are provided, such as on a clamp assembly or integral to a mapping electrode, to produce real time images of device components and surrounding structures.

Device and method for the geometric determination of electrical dipole densities on the cardiac wall

Disclosed are devices, a systems, and methods for determining the dipole densities on heart walls. In particular, a triangularization of the heart wall is performed in which the dipole density of each of multiple regions correlate to the potential measured at various locations within the associated chamber of the heart.

The invention discloses a method, a system, a computer program and a device for determining the surface charge and/or dipole densities on heart walls. Using the foregoing, a table of dipole densities &#x3bd;(P', t) and/or a table of surface charge densities &#x3c1;(P&#x2032;, t) of a given heart chamber can be generated.

Method and device for determining and presenting surface charge and dipole densities on cardiac walls

Disclosed are devices, systems, and methods for determining the dipole densities on a cardiac surface using electrodes positioned on a torso of a patient. Electrodes are integrated into a piece of clothing worn by a patient. The clothing serves to fix the position of the electrodes adjacent a patient's torso. Ultrasonic transducers and sensors are used to determine a distance between the epicardial surface and the electrodes and are also used to detect epicardial surface motion as well as epicardial wall thickness.
