Abstract
This invention describes methods and algorithms for processing a plurality of relevant signals/data intrinsic to a patient and/or derived from external diagnostic equipment for management of atrial arrhythmias. The intrinsic signals are acquired from intracardiac leads/sensors and analogous extrinsic data obtained from imaging equipment and patient demographics. These data are input into software algorithms that use digital signal processing to output informational data of clinical and technical relevance after comparisons are made to patients with access to this technology whose outcome under varying treatments is known. These combined data are used to define prognosis, make treatment suggestions, direct programming of cardiac devices and digitally convert intrinsically and extrinsically derived indices into a common metric. In a preferred embodiment, the intrinsically and extrinsically acquired data is utilized in the design of catheters and software algorithms for performing intracardiac procedures such as ablation of atrial arrhythmias.
