I wonder if this would work with Wolff-Parkinson-White syndrome? I don't know what a "thoracoscopic ablation" is. Is this a surgery which affects the AV node (which, to my very very layperson's understanding, limits the electrical activity that reaches the ventricles of the heart [I cribbed that from Wikipedia *'.'*] - the excitation of which is the issue in WPW.) Wow. Didn't know I was so in to the condition my mother had. - Gienah Ghurab
