ABSTRACT
Methods: We reviewed reports of post COVID dysautonomia and management strategies pursued to understand best practices and provide a primer for clinicians to guide patient management. We reviewed the literature for case reports of post COVID dysautonomia and compiled the cases into a table. Treatment approaches and outcomes were aggregated into an algorithm for management guidance. Results: Ten studies regarding post COVID dysautonomia were reviewed. Strategies included conservative approaches such as fluids, salt consumption, compression stockings, abdominal binders and head of bed elevation as well as strength building such as yoga, resistance exercise, and recumbent physical activity. Moreover, psychosocial support including cognitive behavioral therapy, biofeedback, and support groups were emphasized along with pharmacologic remedies such as midodrine, ivabradine, fludrocortisone, intravenous immunoglobulin, gabapentin, and topical lidocaine in additoin to interventions such as enhanced external counterpulsation. Primary and secondary outcomes included self-report surveys, autonomic laboratory testing, hand grip strength and heart rate variability. Background: Growing numbers of cases of dysautonomia after acute COVID-19 infection are being reported involving previously healthy patients. This post-COVID dysautonomia is predominantly characterized by lingering neurologic and cardiovascular dysfunction including tachycardia, orthostatic intolerance, migraine, exercise intolerance, fatigue, and cognitive impairment. Anxiety, insomnia, and uncertainty surrounding the COVID-19 pandemic present additional risk factors for sympathetic overdrive and deconditioning. Best management strategies and practice guidelines for this patient population remains unknown. Conclusion: Our review suggests consideration of an integrative, multimodal treatment approach involving physical activity, mental well-being, nutrition, stress management, and medication. These primarily facilitate management of dysautonomia, but rarely lead to complete symptom resolution. Despite the uncertainty associated with post-COVID dysautonomia, patient validation, education, and lifestyle approaches provide the cornerstone of management. Since post-COVID dysautonomia will comprise an increasing number of care consultations, clinician awareness, prompt diagnosis, and personalized management are essential.
