<p>The present invention relates to classification and localization of arrhythmias. More specifically, a system and method is provided for developing a database of body surface ECG P wave maps for classification and localization of left-sided atrial arrhythmias (2). The invention includes generating and receiving P wave data in a subject by left atrial pacing or receiving P wave during spontaneously occurring or induced left atrial arrhythmias (4); computing potential or integral maps of the P wave data (8); classifying the maps specific to a left atrial ectopic origin (9); verifying the classification procedure; averaging the classified maps into mean maps (10); and storing and accessing the mean maps in the database (12). The mean maps of the P wave data in the database can be used to automatically classify and localize P wave data from a patient obtained during a left atrial arrhythmia such as atrial tachycardia, focal atrial fibrillation or orthodromic atrioventricular reentrant tachycardia.</p> |
