Tilt testing remains a valuable asset [PDF]
European Heart Journal, 2021 AbstractHead-up tilt test (TT) has been used for >50 years to study heart rate/blood pressure adaptation to positional changes, to model responses to haemorrhage, to assess orthostatic hypotension, and to evaluate haemodynamic and neuroendocrine responses in congestive heart failure, autonomic dysfunction, and hypertension. During these studies,

Progressively invalidating orthostatic hypotension: A common symptom for a challenging diagnosis
Journal of Research in Medical Sciences, 2016 We discuss here an uncommon condition of neurogenic hypotension in the context of immunoglobulin light chain (amyloid light-chain) amyloidosis. The most serious feature was autonomic nervous system impairment, mainly characterized by severe refractory ...
