“…The first case of RCAT was described by Takatsuki and colleagues 5 in 2001, coexisting with Wolff-Parkinson-White syndrome and treated by RFCA, and there have been several subsequent reports of RCAT. 6 , 7 Yamamoto and colleagues 8 demonstrated precisely the clinical characteristics, geometry of origin, EPS, and outcome of RFCA in 7 cases with 9 RCATs. They reported that RCAT appeared to arise from the right pulmonary vein and superior vena cava, and suggested that the mechanism of RCAT was triggered by autonomic nervous system activity modulated by respiration or chest movement itself.…”
