Key result
Monitoring HR and BP with positional and respiratory changes quickly identifies dysautonomia without orthostatic stress.
Why the study?
Many physicians remain unclear on the vast clinical manifestations of dysautonomia, and the lack of clear-cut testing leads to significant diagnostic delays and misdiagnoses.

Simple monitoring of heart rate and blood pressure during positional and respiratory changes offers a rapid, non-invasive method to diagnose dysautonomia and POTS.
A significant number of physicians are unclear of the vast clinical manifestations of dysautonomia and imbalance of the autonomic nervous system, specifically the parasympathetic and sympathetic nervous systems. The major obstacle has been an inability to determine the mechanism of action as well as multisystem dysfunction and a lack of clear-cut testing. Dysautonomia, a pathophysiological malfunction of the sympathetic and parasympathetic nerves in our bodies, can present as altered clinical functions of heart rate (tachycardia/bradycardia), altered breathing patterns, blood pressure (hypertension/hypotension), sweating, digestion, syncope, etc. These symptoms have caused specialists to miss this diagnosis because of relative nonspecificity. Our current analysis of patients demonstrates significant delays in diagnosis, misdiagnosis, and the development of chronic syndromes because of the above. We demonstrate that monitoring of heart rate and blood pressure with changes in position and respiration can be easily and quickly performed without orthostatic stress and can demonstrate the entities of sympathetic withdrawal, cholinergic excessive aspects as well as tachycardia, blood pressure dips with posture, etc. This analysis takes less than an hour without the need for injections or medication, thus more quickly informing the cardiologist/neurologist of the correct diagnosis. We will attempt to demystify these issues so that clinicians and the scientific community will have a better understanding of this entity and consider a diagnosis of dysautonomia earlier in the differential diagnostic process and start treatment approaches sooner.

Weintraub et al. (2024) conducted a review in Dysautonomia and Postural Orthostatic Tachycardia Syndrome. Monitoring of heart rate and blood pressure with changes in position and respiration was evaluated. Monitoring heart rate and blood pressure with changes in position and respiration can quickly identify dysautonomia without orthostatic stress, potentially reducing significant delays in diagnosis.
