Postural Orthostatic Tachycardia Syndrome (POTS)

Postural Orthostatic Tachycardia Syndrome (POTS) Discussion document: Dr Graham Exelby: Mermaidcentralresearch.com.au Summary: Postural orthostatic tachycardia syndrome (POTS) is defined as orthostatic intolerance associated with tachycardia exceeding 120 beats per minute or an increase in the heart rate of 30 beats per minute from baseline within 10 minutes of changing the posture from a lying toContinue reading “Postural Orthostatic Tachycardia Syndrome (POTS)”

Dysautonomia and sleep apnoea

Obstructive sleep apnoea produces major acute haemodynamic changes and causal relationships with arterial hypertension and cardiovascular morbidity have been proposed.(1) Autonomic dysfunction has been independently associated with obstructive sleep apnoea (OSA), and while autonomic abnormalities are generally considered to be secondary to OSA, it is also felt that autonomic dysfunction may also contribute to OSA.Continue reading “Dysautonomia and sleep apnoea”

Preventing Vascular Ageing

Arteriosclerosis is an Inflammatory Process The last decade has shown an increase in the relevance of inflammation and its mediators in vascular biology; thus, the role of inflammation during atherogenesis is now a matter of intense investigation. Basic science studies proved that elements belonging to both innate and adaptive immunity can be involved in theContinue reading “Preventing Vascular Ageing”

Autonomic Nervous System

Acknowledgments: This article is based principally on: ANS Balance Assessment.  Bioscan Medeia Inc.. https://www.bioscan.com/dtr_ans_overview.htm “The Autonomic Nervous System (ANS) is the involuntary division of the nervous system. It consists of autonomic neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to glands, smooth muscle and cardiac muscle. ANS neurons are responsibleContinue reading “Autonomic Nervous System”

Oxidative Stress

“We know that we must constantly consume oxygen in order to carry out normal cellular metabolism. On a cellular basis, oxygen is mostly used in organelles called mitochondria. These organelles have been called our cells’ “power-plants” because this is where raw fuels that we eat (proteins, carbohydrates, and fats) are converted into a useful formContinue reading “Oxidative Stress”
