To characterize the impact of orthostatic hypotension (OH) and reflex syncope on signals
measured using a wearable cardiac monitor prototype device.
To evaluate the relationship of signals measured from the wearable cardiac monitor prototype
device with reported symptom severity of orthostatic intolerance per standard data
collection, analysis, and questionnaires.

This is a non-randomized feasibility study that will enroll up to 50 participants that have
undergone a previous autonomic reflect screen (ARS) assessment and were either diagnosed with
OH or reflex syncope, or considered to be control subjects for this study.
A maximum of 20 subjects diagnosed with reflex syncope, a maximum of 10 subjects diagnosed
with OH and a maximum of 10 control subjects will be enrolled. There will be one study visit
per subject.

Inclusion Criteria:
- Willing and capable to provide informed consent
- Age 18 or above
- No contraindications to undergo tilt table test, Valsalva maneuver test, and deep
breathing test (Components of the ARS assessment)
- Previously underwent a clinically indicated ARS assessment without complications
(including deep breathing, Valsalva maneuver, and tilt table testing). Previously
diagnosed with OH, reflex syncope, OR control subjects assessed as normal, based on
the ARS assessment. Patient enrollment shall be based on the type of diagnosis.
- Willing to participate in one additional tilt table test, Valsalva maneuver test, and
deep breathing test (components of the ARS assessment)
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 medical treatment
- Experienced complications during previous clinically indicated ARS assessment
- Are on medications that could affect autonomic function, if considered not safe or
unwilling to hold such medications for at least four half-lives prior to testing
(judged by the study Principal Investigator)
- Have any contraindication for tilt test, Valsalva maneuver test or deep breathing test
