This prospective, pragmatic, randomized controlled trial aims to evaluate the efficacy and safety of transcutaneous acupoint electrical stimulation (TAES) for patients with frequent premature ventricular contractions (FPVCs). Ninety participants will be randomized to TAES group and sham-TAES group with the ratio of 1:1. They will receive TAES plus usual care or sham-TAES 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 contractions (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.
