Abstract: Software and apparatus are provided to automatically detect and map areas of complex fractionated electrograms within cardiac chambers. Electrogram signal are analyzed to count the number of complexes whose amplitude and peak-to-peak intervals meet certain criteria. Functional maps indicating average complex interval, shortest complex interval, and confidence levels are produced for display.

Abstract: A reliable endocardial map is obtained by constructing a matrix relationship between a small number of endocardial points and a large number of external receiving points using a multi-electrode chest panel. Inversion of the matrix yields information allowing the endocardial map to be constructed. Subsequent maps are obtained noninvasively using the multi-electrode chest panel, applying new electrical signals to the matrix relationship, and again inverting the matrix to generate new endocardial electrical maps.

Abstract: A device for enhancing visualization of an esophagus when imaged by a visualization system includes a structure including material that is clearly visible when imaged by the visualization system. The structure is arranged, when inserted into the esophagus, to expand so as to conform to an inner surface of the esophagus in order to enhance a visualization quality of the surface when imaged by the visualization system. A cord attached to the structure is arranged to extend out of the esophagus so as to assist a removal of the device from the esophagus.

Abstract: A method for performing a medical procedure is provided, including recording geometric information at a plurality of time points in a plurality of cardiac cycles of a heart of a subject. Subsequently, a transient event is detected that is produced at a location on the heart during a cardiac cycle. A time of occurrence of the transient event is identified in the cardiac cycle during which the transient event occurred. A map of the heart is displayed responsive to the identified time of occurrence and the geometric information recorded at a time point in the cardiac cycle that corresponds to the time of occurrence of the transient event.

Abstract: A novel apparatus and method for rapidly generating an electrical map of a chamber of a heart utilizes a catheter including a body having a proximal end and a distal end. The distal end has a distal tip and an array of non-contact electrodes having a proximal end and a distal end and at least one location sensor. Preferably, two location sensors are utilized. The first location sensor is preferably proximate to the catheter distal tip and the second location sensor is preferably proximate to the proximal end of the non-contact electrode array. The catheter distal end further preferably includes a contact electrode at its distal tip. Preferably, at least one and preferably both of the location sensors provide six degrees of location information. The location sensor is preferably an electromagnetic location sensor. The catheter is used for rapidly generating an electrical map of the heart within at least one cardiac cycle and preferably includes cardiac ablation and post-ablation validation.

Abstract: A method for dynamic embedding of objects into context selectable locations in digital media items to form versions of said digital media items, said method comprising the steps of: finding context suitable locations in said visual media; dynamically selecting a subset of said objects for at least one location; and embedding one object of said subset of objects in said at least one location, thereby to form a version of said digital media item.
