Abstract
A method and apparatus for developing a database of mean body surface ECG flutter wave data maps for classification of atrial flutter are described. ECG signals from a plurality of torso sites and multisite endocardial recordings are obtained during CCW and CW typical atrial flutter and atypical atrial flutter. Flutter wave episodes are divided into two or three successive time intervals showing stable potential distributions from which data maps are computed. Body surface mapping of CCW and CW typical atrial flutter and atypical atrial flutter is compared with endocardial activation sequence mapping to confirm validity between the body surface ECG pattern and the underlying right or left atrial activation sequence. The body surface ECG map patterns of CCW and CW typical atrial flutter are characterized by a stereotypical spatial voltage distribution that can be directly related to the underlying activation sequence and are highly specific to the direction of flutter wave rotation. The mean body surface ECG flutter wave data maps present a unique reference database for improved clinical detection and classification of typical and atypical atrial flutter.
