Study Arms (1)

Auricular Vagal Nerve Stimulation

EXPERIMENTAL

Patients will undergo a standard EPS with 4 catheters. Following the standard EPS, patients will be hooked up a Parasym device to provide transcutaneous electrical stimulation to the auricular branch of the vagus nerve, EPS will be repeated.

Device: Auricular Vagal Nerve Stimulation

Interventions

The Parasym device will be placed on the patient's left tragus to provide transcutaneous electrical stimulation to the auricular branch of the vagus nerve.

Auricular Vagal Nerve Stimulation

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Primary indication for EPS for the evaluation of cardiac conduction system or supraventricular tachycardia.

You may not qualify if:

  • Previous EPS with ablation
  • Previous failed ablation
  • Known conduction system disease, right or left bundle branch block on EKG
  • Pregnant women
  • History of postural orthostatic tachycardia syndrome
  • Patients who have had prior cervical vagotomy
  • Patients with skin on the tragus that is broken or cracked
  • Patients with a history of baseline cardiac disease or atherosclerotic cardiovascular disease, including congestive heart failure (CHF), known severe coronary artery disease or recent myocardial infarction (within 5 years) and patients diagnosed with narrowing of the arteries (carotid atherosclerosis)
  • Patients with an active implantable medical device, such as a cardiac pacemaker, hearing aid implant, or any implanted metallic, implanted vagus nerve stimulator or electronic device.
