Cardiovascular dynamics during head-up tilt assessed via pulsatile and non-pulsatile models

Nakeya D. Williams, Renee Brady, Steven Gilmore, Pierre Gremaud, more

Journal of Mathematical Biology > 2019 > 79 > 3 > 987-1014

This study develops non-pulsatile and pulsatile models for the prediction of blood flow and pressure during head-up tilt. This test is used to diagnose potential pathologies within the autonomic control system, which acts to keep the cardiovascular system at homeostasis. We show that mathematical modeling can be used to predict changes in cardiac contractility, vascular resistance, and arterial compliance,...

Pediatric dysautonomia: Much‐maligned, often overmedicated, but not as complex as you think

Camden L. Hebson, Michael E. McConnell, David W. Hannon

Congenital Heart Disease > 14 > 2 > 156 - 161

Dysautonomia is an increasingly recognized yet still poorly understood disease within the field of pediatrics. Symptoms, including dizziness, headaches, fatigue, joint pain, anxiety, and intolerance of heat or cold, are often significant and difficult to sort, especially in terms of their relation to each other. This often leads to referral to multiple subspecialists, who then proceed to treat seemingly...

Postural orthostatic tachycardia syndrome: clinical presentation, aetiology and management

A. Fedorowski

Journal of Internal Medicine > 285 > 4 > 352 - 366

Postural orthostatic tachycardia syndrome (POTS) is a variant of cardiovascular autonomic disorder characterized by an excessive heart rate increase on standing and orthostatic intolerance. POTS affects younger individuals 15–45 years old with a distinct female predominance (≈80%). The prevalence ranges between 0.2% and 1.0% in developed countries. The onset of POTS is typically precipitated by immunological...

Nakeya D. Williams, Jesper Mehlsen, Hien T. Tran, Mette S. Olufsen

Biological Cybernetics > 2019 > 113 > 1-2 > 149-159

This paper presents an optimal control approach to modeling effects of cardiovascular regulation during head-up tilt (HUT). Many patients who suffer from dizziness or light-headedness are administered a head-up tilt test to explore potential deficits within the autonomic control system, which maintains the cardiovascular system at homeostasis. This system is complex and difficult to study in vivo,...
