Study Details

Brief summary:

To characterize the impact of orthostatic hypotension (OH) and Vasovagal syncope on signals measured using a wearable Holter monitor in the clinic and ambulatory setting.

To evaluate the relationship of signals measured from the Holter monitor with reported symptom severity of orthostatic intolerance per standard data collection, analysis, and questionnaires.

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Willing and capable to provide informed consent
  • Age 18 or above
  • Previously underwent a clinically indicated ARS assessment without complications (including deep breathing, Valsalva maneuver, and tilt table testing).
  • Previously diagnosed with OH, Vasovagal syncope, OR control subjects assessed as normal, based on the ARS assessment. Participant enrollment shall be based on the type of diagnosis.
  • Willing to complete all required study activities.

Exclusion Criteria:

  • Currently enrolled in another clinical trial that might interfere with data collection.
  • Subject is pregnant or planning to become pregnant during the study
  • Active Implantable Medical Device, e.g. cardiac implantable electronic devices, bladder stimulators, diaphragm stimulators, implantable neuro stimulator, implantable active monitoring devices, implantable active drug administration devices, etc.
  • Have a prosthetic cardiac valve or previously underwent cardiac valve surgery.
  • Known allergy to materials used in the study (adhesive, ECG electrodes)
  • Diagnosed with syncope due to cardiologic causes.
  • Have had a myocardial infarction in the previous 90 days
  • Have been diagnosed with tachycardia that requires current medical treatment
  • Have any contraindications for exercise testing, tilt table test, Valsalva maneuver test or deep breathing test (judged by the study Principal Investigator)

Interventions and Outcome Measures

Arms

Syncope group

Patients that have undergone an ARS assessment and diagnosed with orthostatic hypotension or reflex syncope

Control Group

Patients that have undergone an ARS assessment and are control subjects.

Interventions

Wearable holter monitor

Participants will be fitted with a minimum of one wearable Holter monitor and up to 2 monitors, placed on the skin that measures physiologic signals. Participants will wear the monitor(s) for up approximately 21 days.
