This prospective, randomized controlled trial aims to evaluate the efficacy and safety of Transcutaneous Auricular Vagus Nerve Stimulation (TAVNS) for patients with frequent premature ventricular coomplexes (FPVCs). Ninety participants will be randomized to TAVNS group and sham-TAVNS group with the ratio of 1:1. They will receive TAVNS plus usual care or sham-TAVNS plus usual care for 6 weeks, and then be followed up for 12 weeks after the treatment. The primary outcome was the proportion of participants with a 50% decrease of the 24 hour (24h) premature ventricular complexes (PVCs) after 6-week treatment. Secondary outcomes include the proportion of participants with a 75% decrease of the 24h-PVCs; the decrease from baseline of 24h-PVCs, total 24h-heartbeat, and the frequency of supraventricular arrhythmia; the score change from baseline in PVCs-related symptoms; the score change from baseline in SAS and SDS. Subgroup analyses will be performed in age, gender, and the severity of PVCs. Safety assessment will be documented during the whole trial.

| Sham Transcutaneous Auricular Vagus Nerve Stimulation (Sham-TAVNS) | Device | Patients in sham-TAVNS group will receive sham-TAVNS and usual care. Sham-TAVNS will be also performed on Erzhong and Xin (Auricular Acupuncture Point with vegas nerve stimulation) for 6 weeks by using a special Huato type SDZ-V stimulator. We cut the inner electric wire of the stimulator; therefore, there is no current output. Usual Care: usual medicine treatment for PVCs. |
|
| the proportion of participants with a 75% decrease of PVCs from baseline |
The PVCs will be assessed by a 24-hour Holter monitoring. The investigators will calculate the decrease of PVCs between baseline and week 6/18, then we will obtain the proportion of patients with a 75% decrease. |
| week 6, week 18 |
| the change from baseline in PVCs | The PVCs will be assessed by a 24-hour Holter monitoring. The investigators will calculate the decrease of PVCs between baseline and week 6/18. | week 6, week 18 |
| the change from baseline in total cardiac impulse | The total cardiac impulse will be assessed by a 24-hour Holter monitoring. The investigators will calculate the change of total cardiac impulse between baseline and week 6/18. | week 6, week 18 |
