C: the intracavitary mapping system. D: the butterfly plot of the intracavitary electrograms. E: the reconstructed activation sequence and the estimated initiation site by 3DCEI. F: the reconstructed electrograms by 3DCEI. G: the reconstructed cardiac activities by the intracavitary mapping system.
