About this study
The primary objective of this research is to study direct electrical stimulation of central autonomic network for blood pressure control.
Read the detailed description
This project aims to include 20 participants, and evaluate the direct electrical stimulation of central autonomic network for blood pressure control through A pilot, prospective clinical trial. It is expected to explore potential blood pressure regulation-related targets in the central autonomic neural network and provide a neuromodulation approach for the treatment of blood pressure disorders, including refractory hypertension and neurogenic orthostatic hypotension.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
direct electrical stimulationOther
The intervention consists of direct electrical stimulation delivered at three distinct frequencies (10 Hz, 50 Hz, and 120 Hz). A double-blind design will be employed to randomly assign one of these frequencies for a 30-second direct electrical stimulation session in each patient.
| Study group | Role | What they receive |
|---|---|---|
| Direct electrical stimulation | Experimental | Patients with hypertension and drug-resistant focal epilepsy who underwent intracranial monitoring via stereotactically implanted depth electrodes (SEEG) are assigned to Direct electrical stimulation for 30 sec per mission. Receives: Other: direct electrical stimulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
blood pressure
Blood Pressure is defined as the blood pressure measurement obtained 30 minutes after the completion of direct electrical stimulation.
Measured: up to 4 hours

Questions about this trial
What is this clinical trial studying?
A study testing direct electrical stimulation in people with Blood Pressure Control and Hypertension, run by Xuanwu Hospital, Beijing.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 28 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Liankun Ren, MD (+86 13681576621, renlk2022@outlook.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
blood pressure (time frame: up to 4 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2026; AzTrials last refreshed its copy on 7 Nov 2026.
