Understanding Blood Volume & Hemodynamics in POTS

In this comprehensive webinar, Dr. Satish Raj explains the complexities of blood volume and hemodynamics in POTS (Postural Orthostatic Tachycardia Syndrome). The discussion emphasizes the common issue of hypovolemia, or low blood volume, in POTS patients, which can lead to excessive heart rate increases and a range of troubling symptoms. Dr. Raj details how various mechanisms, such as the renin-angiotensin-aldosterone system, are believed to contribute to these blood volume issues. The webinar covers a variety of management strategies, both nonpharmacological and pharmacological, to increase blood volume or improve blood flow, including high salt diets, oral rehydration solutions, compression garments, and the potential use of medications like desmopressin and DDAVP. Dr. Raj highlights the benefits and challenges of these treatments and presents recent research findings, such as the impact of high salt intake on plasma volume and heart rate. The presentation underscores the importance of individualized treatment plans based on symptoms and responses to various interventions.
