Hypertension, the most prevalent chronic condition, is regarded as the leading risk factor for cardiovascular disease and renal diseases.Acupuncture, a vital component of traditional Chinese medicine, has been utilized as a nondrug therapy for treating patients with cardiovascular disease.Based on the above, the pilot trial is expected to investigate the effectiveness and safety of TEAS for hypertension by comparing it with usual care; to explore the optimal transcutaneous electrical stimulation frequency by comparing different stimulation frequencies at 2 Hz and 10 Hz. Further, it will lay a foundation for future large clinical trials and provide a reference for the parameter setting of biofeedback electric stimulation devices.
