The most frequent tachyarrhythmia in the world is atrial fibrillation (AF). The global prevalence of AF is currently 37,574 million (0.51% of the global population), by 2050, the morbidity of AF is expected to rise by more than 60% (Chugh et al., 2014;Lippi et al., 2021). It has a high mortality, morbidity, hospitalization rates and economic spending, all of which put a strain on the global health system and make it a global health threat (Hindricks et al., 2021). The number of AF patients in China is estimated to be around 4,870,000 (Wang et al., 2018). The most effective treatment for AF, radiofrequency catheter ablation (RFCA), is strongly recommended in the 2020 ESC guidelines, greatly lowering the burden of symptoms (Kalla et al., 2017). Patients' symptoms (palpitation, fatigue, recurrence, etc.) cannot be eased immediately after RFCA, putting their psychological well-being at risk. The psychological problem is more evident in the postoperative "Blanking Period" (Sang et al., 2013).The first 3 months after surgery is known as the "Blanking Period,"
