Does acute transcutaneous auricular vagus nerve stimulation improve blood pressure and cardiac autonomic modulation in healthy and hypertensive individuals?
A single session of acute transcutaneous auricular vagus nerve stimulation has limited clinical impact on blood pressure and autonomic modulation in healthy and hypertensive individuals.
Acute taVNS induces site- and group-dependent cardiovascular responses, with limited clinical impact after a single session. These findings suggest that short-term stimulation may be insufficient to overcome impaired autonomic regulation in hypertension and highlight the need for repeated or longer stimulation protocols in future clinical trials.
