Using electrical stimulation of the ear to improve heart rate variability

Transcutaneous Electrical Auricular Vagus Stimulation and Heart Rate Variability

Not applicable Interventional Bakulev Scientific Center of Cardiovascular Surgery · NCT05680337

This study is testing whether using electrical stimulation on the ear can help improve heart rate variability in people, which might lead to better treatments for conditions like depression and chronic pain.

What this trial studies

This study investigates the effects of transcutaneous electrical stimulation of the auricular vagus nerve on heart rate variability, a potential biomarker for autonomic nervous system function. Participants will receive low-frequency electrical impulses aimed at modulating vagal activity, which may provide a non-invasive alternative to traditional vagus nerve stimulation methods. The study aims to clarify the ambiguous data surrounding the relationship between this stimulation technique and heart rate variability, which has implications for various health conditions. By determining a reliable biomarker for successful vagus nerve activation, the research could enhance treatment strategies for conditions like depression and chronic pain.

Who should consider this trial

Good fit: Ideal candidates include individuals with sinus rhythm who are seeking alternative treatments for conditions like depression or chronic pain.

Not a fit: Patients with frequent ventricular or supraventricular extrasystole, advanced AV block, or severe chronic renal or liver pathology may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could offer a non-invasive treatment option for patients with conditions related to autonomic nervous system dysfunction.

How similar studies have performed: While some studies have shown positive effects of similar stimulation techniques, the relationship between TENS and heart rate variability remains under investigation and is not yet fully established.
