Patient undergo right pulmonary vein isolation under general anesthesia.After successful isolation of the right pulmonary vein, use a 25-gauge stainless steel millineedle of different lengths to be ordered sequentially according to the acupuncture point prescription.Acupuncture was performed at Hegu and Neiguan points on the left side of the patient.After the manual acupuncture, the point was continuously stimulated by an electrical stimulator to analgesia,the frequency is 200 times / min, the pulse frequency is 3 ~ 4Hz. The output intensity is subject to the patient's tolerance, generally 20mA.The electroneedle stimulates until the end of the left pulmonary vein isolation.

The acupuncture was combined with intravenous use of morphine to achieve anesthesia during the ablation procedure

Pain was assessed by Visual Analogue Score (VAS).VAS is one of the commonly used pain scoring standards. The full name is the visual simulation scoring method. The pain is divided into 10 points, 2 points for no pain, 10 points for severe pain, and the middle part for different degrees of pain.To compare the scores of patients during pulmonary vein isolation procedure.

The incidence of nausea, vomiting and retching within 12 hours after operation was recorded, including 3 dimensions of symptom experience time, frequency and severity, with 8 items in total. 0~4 points shall be used for 5 grades. 0 points means none at all, and 4 points means very serious and intolerable.

To compare the dose of morphine used during pulmonary vein isolation procedure.
