  Purpose

Syncope is a common problem that many clinicians may encounter in various outpatient settings. Neurocardiogenic syncope (NCS) is a benign condition characterized by a self limited episode of systemic hypotension. Patients are usually managed with education on syncope, anxiety management, and coping skills.

It has been established that practice of Yoga could relieve stress and anxiety. In a different study, they also found that Yoga positively influences cardiovascular function by decreasing the heart rate and blood pressure. The main objective of Yoga is to achieve control over the autonomic nervous system and able to control functions like heart rate, blood pressure and respiratory rate.

Based on the findings that Yoga relieves stress and reduces heart rate, the investigators propose to study if Yoga can decrease the frequency of NCS and also reduce the symptoms associated with these episodes.

Primary Outcome Measures:
  • Change in frequency of recurrent syncopal spells in patients with Neurocardiogenic syncope (NCS) [ Time Frame: Baseline to 3 Months ]
    Differences in the incidence of syncopal spells pre and post Yoga.

  • Change in frequency of recurrent syncopal spells in patients with Neurocardiogenic syncope (NCS) [ Time Frame: Baseline to 1 Year ]
    Differences in the incidence of syncopal spells pre and post Yoga.

  • Change in frequency of recurrent syncopal spells in patients with Neurocardiogenic syncope (NCS) [ Time Frame: Baseline to 1 Year ]
    Differences in the incidence of syncopal symptoms pre and post Yoga.


Secondary Outcome Measures:
  • Change in Heart Health [ Time Frame: 3 Months, 1 Year ]
