This paper summarized professor RUAN Shiyi′s experience in prevention and treatment of atrial fibrillation recurrence after radiofrequency ablation. It is believed that staged diagnosis and treatment methods should be followed before and after radiofrequency ablation. Before the operation

the main manifestation of patients is deficiency syndrome

with heart yang qi deficiency as the branch and spleen-kidney depletion as the root. Therefore

kidney yin and kidney yang should be balanced

and spleen qi should be fortified

thereby preventing postoperative recurrence of atrial fibrillation by supplementing both spleen and kidney and nourishing heart yang. In the short-term period after the operation

binding of phlegm and stasis is most commonly seen

when vessels and collaterals of the heart are constrained leading to disharmony of pulse rhythm; herbs of salty and cold flavors are recommended to soften hardness and dissipate masses

thereby regulating pulse rhythms. In the late postoperative period

regulation of recurrence risk factors from multiple aspects such as controlling basic diseases and life styles is suggested; for treatment

both heart care and healthy pulse maintaining therapies should be applied so that the heart itself and its normal functions can work well.
