Breathing Device in Postural Orthostatic Tachycardia Syndrome (POTS)

2014-07-23 21:13:35 | BioPortfolio

Summary

The investigators will test whether breathing through an inspiratory resistance device will improve the ability to be upright and decrease heart rate increases on standing in patients with postural tachycardia syndrome.

Description

Chronic orthostatic intolerance, sometimes known as the postural tachycardia syndrome (POTS), is the most common disorder among patients seen at several centers specializing in diseases of the autonomic nervous system. It affects an estimated 500,000 people in the United States alone. POTS (excessive increase in heart rate [>30 min-1] on standing associated with orthostatic symptoms [including palpitation, chest pain syndrome, dyspnea on standing, mental clouding and difficulties with concentration], in the absence of orthostatic hypotension) can produce substantial disability among otherwise healthy people. Patients with POTS typically feel tired and run down. Many also report a myriad of symptoms that are hard to categorize, often involving fatigue. One study, from the Mayo Clinic, found that patients with POTS had a diminished quality of life when measured using a standard health status instrument (SF-36).

In this pilot study, we will test the hypothesis that breathing through an inspiratory resistance device will improve orthostatic tolerance and reduce orthostatic tachycardia in patients with postural tachycardia syndrome.

Medical and Biotech [MESH] Definitions

The maximum volume of air that can be inspired after reaching the end of a normal, quiet expiration. It is the sum of the TIDAL VOLUME and the INSPIRATORY RESERVE VOLUME. Common abbreviation is IC.

The smallest difference which can be discriminated between two stimuli or one which is barely above the threshold.

The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.

Removal of a MEDICAL DEVICE from the market due to the identification of an intrinsic property of the device that results in a serious risk to public health.

Loss of sensitivity to sounds as a result of auditory stimulation, manifesting as a temporary shift in auditory threshold. The temporary threshold shift, TTS, is expressed in decibels.
