Brief Summary
This study is to investigate the correlation and to obtain the coefficient of correlation between the global and local bipolar signals (voltage maps) of the LA in sinus rhythm using a focal 4.5 mm irr...
Detailed Description
Current hypothesis of the mechanism of atrial fibrillation (AF) is a combination of local firing mainly triggered from the pulmonary veins and atrial substrate due to atrial remodelling sustaining AF....
