Orthrostatic Tachycardia Answer Posted By CCFMD-CRC on Thursday, April 19, 2001 Dear Robert, postural orthostatictachycardia syndrome (POTS) is a form of autonomic dysfunction that http://www.medhelp.org/forums/cardio/messages/32763a.html
Extractions: I don't know if you can direct me to where I can find an answer. I have looked through the forum of questions and I found no answers. I want to know what they can do about Orthrostatic tachycardia. It is a very bad problem that no one but my endocrinologist wants to address but he has to go through my primary care physcian. That was a year ago and nothing has been done. I just wanted to know if there is a device that can control my heart beat down to a regular beat. Resting it is about 100, up it jumps to 130 to 160 and don't know how high it was when I almost passed out in the bath tub.

Extractions: What is Orthostatic Intolerance? When orthostatic symptoms occur in patients, but blood pressure does not fall as much as 20/10 mmHg on assumption of upright posture, the patient has orthostatic intolerance (OI). Additional criteria used for the diagnosis of OI at Vanderbilts Autonomic Dysfunction Center include an increase in heart rate of at least 30 beats per minute with standing, and a standing plasma norepinephrine level of at least 600 pg/ml. Because upright heart rate is usually greatly increased, the term Postural Tachycardia Syndrome (POTS) is also used. Demographics Orthostatic intolerance affects an estimated 500,000 Americans and causes a wide range of disabilities. It is a disorder that more frequently affects young women ( female-to-male ratio at least 4:1), often less than 35 years of age. Most of these patients experience an excessive heart rate increase when they stand. This heart rate increase is a sign that the cardiovascular system is working hard to maintain blood pressure and blood flow to the brain in the presence of a disordered cardiovascular regulation.

Extractions: ORTHOSTATIC HYPOTENSION Timothy C. Hain, MD. Please read our Return to Index . Content last updated: 12/2002 Orthostasis means upright posture, and hypotension means low blood pressure. Thus, orthostatic hypotension consists of symptoms of dizziness, faintness or lightheadedness which appear only on standing, and which are caused by low blood pressure. Only rarely is spinning vertigo caused by orthostasis. Symptoms that often accompany orthostatic hypotension include chest pain, trouble holding the urine, impotence, and dry skin from loss of sweating. Blood pressure is maintained by a combination of several things. The heart is the central pump, and a weak or irregular heart can cause orthostasis. Conditions such as arrhythmia, heart failure, deconditioning, and pregnancy are examples where the heart may not be up to the task of providing an adequate blood pressure. The heart pumps blood, and if there is too little blood volume (anemia, dehydration, dialysis), the pressure drops. The blood vessels in the body also can squeeze (constrict) to raise blood pressure, and if this action is paralyzed, blood pressure may fall. Numerous medications affect blood vessels including most of the medications used for blood pressure, and many of the medications used in psychiatry and for anginal heart pain. Heat, such as a hot shower or from a fever can also dilate blood vessels and cause orthostasis. The nervous system senses and responds to regulate blood pressure. If something is wrong in this control system, blood pressure may fluctuate.

Extractions: Peter C. Rowe, MD Re: Revised Chronic Fatigue Syndrome Guidelines To Whom It May Concern: I have had an opportunity to review the revised Australian CFS guidelines. I am disappointed by the complete failure to integrate the scientific evidence regarding circulatory abnormalities in CFS. In a detailed letter on the draft guidelines written to Dr. Loblay in April of 1998, I discussed ways in which the guidelines might better acknowledge the association between CFS and syndromes of orthostatic intolerance. Despite the fact that many more scientific studies have emerged on this topic in the past three years, the current revision of the guidelines contains even less on orthostatic intolerance. As Wessely and colleagues emphasized in a JAMA article in 1998, the failure to integrate literature from many sources perpetuates pre-existing disciplinary biases in reviews on CFS, and an analogous failure to discuss a large literature on orthostatic intolerance in CFS affects the revised guidelines. A variety of disorders of orthostatic intolerance, most notably postural tachycardia syndrome and neurally mediated hypotension, are characterized by symptoms similar to those seen in CFS. The symptoms in common include chronic fatigue, difficulty thinking and concentrating, headaches, myalgias and chest wall pain, nausea, palpitations, and anxiety. In Jacob¼s recent study of postural tachycardia syndrome, chronic fatigue was reported by 67%. Even if one is not enthusiastic about the overall contribution of orthostatic tachycardia and hypotension to the pathophysiology of symptoms in CFS, some mention of these disorders surely belongs in any section describing the differential diagnosis of chronic fatigue.
