Brief Summary

Japanese Cather Ablation (J-AB) Registry is a voluntary nationwide registry, performed by Japanese Heart Rhythm Society, collaborated with the National Cerebral and Cardiovascular Center. The objectives of this registry are to observe and describe developments in the catheter ablation treatment of arrhythmia in Japan and to provide reliable information on the type of activity performed and the facilities available in Japanese arrhythmia units.
