Inappropriate sinus tachycardia (IST) is an uncommon form of atrial tachycardia. The term "inappropriate" in medicine is commonly defined as a heart rate greater than 100 beats per minute at rest or with minimal physiological challenge. IST is characterized by an increased resting heart rate with an exaggerated response to exercise or stress.

Yoga has been used extensively around the world as an alternative medicine approach in treating numerous chronic and debilitating diseases. Studies have been conducted in various countries to determine the benefits of Yoga as therapy for these chronic diseases. Several studies have confirmed that yoga can reduce anxiety and regulate the stress response.

Studies in the past have shown that Yoga relieves stress, one of the most common triggers for the arrhythmia and increased heart rate in IST. Based on past studies we hypothesize that patients with IST might benefit by practicing yoga. Yoga may also help in better rate and rhythm control with yoga when employed in combination with usual medical arrangement.

Condition Intervention
Inappropriate Sinus Tachycardia
Other: Yoga

Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: The Effect of Yoga on Arrhythmia Burden and Quality of Life in Patients With Inappropriate Sinus Tachycardia

Further study details as provided by University of Kansas Medical Center:

Primary Outcome Measures:
  • Determine if Yoga affects the rate and duration of IST episodes [ Time Frame: Change from Baseline to 3 Months ]
  • Determine if Yoga affects the rate and duration of IST episodes [ Time Frame: Change from Baseline to 1 Year ]

Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Yoga
Participants will be asked to practice yoga 3 days per week, at a minimum and encouraged to practice 7 days per week, for 1 year.
Other: Yoga
The subjects will be asked to practice Yoga poses at least 3 times a week at home, although daily Yoga will be encouraged. Participants will be trained in breathing exercises, postures and meditation. Each time they practice yoga will be for 1 hour and include breathing exercises, postures and meditation.
