To characterize the cardiac rhythm disturbances catheter-based cardiac mapping approaches have become a common practice due to their minimal invasiveness. A multielectrode basket-shaped contact catheter and the multielectrode intravenous catheter are two types of the used catheters. Catheter based approaches provide mapping of the one surface at a time. Therefore, there is a need for a method that...
Due to their minimal invasiveness catheters are highly prefered as cardiac mapping techniques used in the source localization of rhythm disturbances in the heart (arrhythmias). It is known that most of arrhythmias originate from the inner surface of the heart (endocardium). In mapping this surface two catheter-based approaches are used which are called standart and multielectrode basket catheters...
One of the epicardial mapping techniques requires the insertion of multiple multi-electrode catheters into the coronary vessels. The recordings from the intracoronary catheters reflect the electrical activity on the nearby epicardial sites; however, most of epicardial surface is still inaccessible. In order to overcome this limited access problem, a method called the linear least squares estimation...
