Current Status and Future of Cardiac Mapping in Atrial Fibrillation [chapter]

Doosang Kim, Hyuk Ah
2012 Atrial Fibrillation - Basic Research and Clinical Applications  
To improve the success rate, exact cardiac mapping of AF is essential.  ...  Every year, 3 million suffer from AF related stroke, 1.5 million die from AF related stroke within a year, and 1 million are severely disabled by AF related stroke.  ...  By the co-registration process between MCG and CT, the volumetric conductor models were established.  ...
