Non-invasive Vagal Neurostimulation (nVNS) in Adolescents With Postural Orthostatic Tachycardia Syndrome (POTS)
Pilot Study--The Effects of Non-invasive Vagal Neurostimulation (nVNS) in Adolescents With Postural Orthostatic Tachycardia Syndrome (POTS)

Conditions
Intervention / Treatment
Detailed Description
Project purpose: The investigators will study the use of non invasive vagal nerve stimulation in newly diagnosed adolescent patients with POTS to see if symptom management improves over 2 months. Surveys will include COMPASS-31. Child Functional Disability Inventory, and PHQ-9. Patient logs will evaluate headache frequency, exercise duration and VNS use.
Research objectives: The investigators hypothesize that:
Primary Aim 1. Use of noninvasive vagal nerve stimulation will decrease autonomic symptom intensity compared to control group.
Primary Aim 2. Use of noninvasive vagal nerve stimulator will improve child function.
Primary Aim 3. Heart rate elevation measured by head up tilt table test will decrease in the treatment group compared to the control group.
Secondary goals include:
Secondary Aim 1: To determine if utilization of noninvasive vagal nerve stimulation influences headache frequency Secondary Aim 2: Determine if utilization of noninvasive vagal nerve stimulation will influence weekly duration of aerobic exercise.
Secondary Aim 3: Determine if utilization of noninvasive vagal nerve stimulator results in significant side effects, particularly depression, in adolescent patients.

Active Comparator: Standard Postural Orthostatic Tachycardia Syndrome management/ STEPS
The General Pediatric and Adolescent Medicine providers at Mayo Clinic utilize a specific management program for their patients with Postural Orthostatic Tachycardia Syndrome utilizing the acronym STEPS.
S is for liberal intake of salt, T is for drinking 90-100 ounces/day of fluid, E is for slowly and gradually improve continuous aerobic exercise duration to a goal of 50 minute most days of the week, P is for possible utilization of 1 of two prescription medications (metoprolol or midodrine), and S is for setting priorities and goals such as encouraging good sleep hygiene, attendance at school, social interactions, and counseling.
|
STEPS is the acronym for the standard management program for our patients with POTS.
It includes liberal use of salt, taking in 90-100 ounces of fluid, gradually increasing the duration of aerobic exercise, possible use of one of two prescription medications (metoprolol, and midodrine), and encouragement to set priority and goals
|
Experimental: STEPS + GammaCore Intervention (noninvasive vagal nerve stimulation)
Utilization of STEPS management goals plus the addition of non invasive vagal nerve stimulators for two 2 minutes of intervention performed three times a day.
