Evaluation of the effectiveness and safety of acupuncture in the treatment of premature ventricular contractions A protocol for systematic review and meta-analysis

Background: Premature ventricular contractions are the most common type of arrhythmia. The clinical symptoms are mainly palpitations. In severe cases, syncope, angina pectoris and heart failure may occur, which seriously affect people's lives and ability to work. Antiarrhythmic drugs have many side effects and should not be taken for long periods. Acupuncture has a significant effect on the treatment of premature ventricular contractions. Therefore, to evaluate the effectiveness and safety of acupuncture in the treatment of premature ventricular contractions, we conducted this study, with the goal of providing a scientific methodology for this alternative treatment. Methods: We searched PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, China Science Journal Database, and China Biomedical Literature Database. We selected all randomized clinical trials related to the use of acupuncture in the treatment of premature ventricular contractions published on or before October 10, 2021, and we will conduct literature screening and data extraction based on specific inclusion and exclusion criteria. We will use the bias risk assessment tool from the Cochrane Systematic Review Manual to evaluate the quality of the research selected for inclusion in our study. RevMan5.3 software will be used to perform statistical analysis on the data. Results: The results of this study will provide evidence for the effectiveness and safety of acupuncture in the treatment of premature ventricular contractions. Conclusion: The purpose of this study is to explore the efficacy of acupuncture in the treatment of patients with premature ventricular contractions and to provide an effective reference for clinicians and patients on its use.
