Post subject: Postural Orthostatic Tachycardia Syndrome Earlier this year I had multiple episodes of syncope (approx 50). In an earlier post you recommended that I underwent EEG, CT brain and Tilt Testing. I saw my cardiologyist and had tilt table testing which didn't induce syncope but showed multiple episodes of pre-syncope with hypotension (95/85) and sinus tachycardia (up to 170/min). I was diagnosed as having vasodepressor component malignant vasovagal syncope and was told it was probably POTS.

Extractions: Wheelchairs Lifts The syndrome was identified as such by Schondorf and Low in . Similar symptoms were collectively described as "idiopathic hypovolemia" by Fouad in The sudden increase in heart rate upon standing is often accompanied by hypotension, and associated with dizziness, fatigue, and nausea. About 80 percent of patients diagnosed with POTS are female. The causes of POTS are not fully known. It is generally believed to be a case of dysautonomia . Its onset is sometimes associated with an inflammatory condition such as a viral infection. An overlap of symptoms with Chronic fatigue syndrome may suggest a pathological overlap in some cases. A head-up tilt table test consists of a patient resting, strapped to a table in the supine position for several minutes. The table will then be tilted to a nearly vertical position. Heart rate and blood pressure are measured in both positions. The standard for diagnosis is usually the heart rate experiencing a sustained increase of at least 30 beats per minute, or a sustained increase to a total of at least 120 beats per minute.

Extractions: Orthostatic Intolerance a syndrome including neurally mediated hypotension, delayed orthostatic hypotension, and postural orthostatic tachycardia syndrome is found in almost all adolescents with CFS: Rowe, PC. General Information Brochure on Orthostatic Intolerance and its Treatment . Chronic Fatigue Clinic, Johns Hopkins Children's Center, February 2003 " We conclude that chronic fatigue syndrome is highly related to orthostatic intolerance in adolescents. The orthostatic intolerance of CFS often has heart rate and BP responses similar to responses in the syndrome of orthostatic tachycardia suggesting that a partial autonomic defect may contribute to symptomatology in these patients." ~ Julian Stewart, MD, PhD Rowe PC, Barron DF, Calkins H, Maumenee IH, Tong PY, Geraghty MT:

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.
Extractions: Neurally Mediated Hypotension and CFS Peter C. Rowe, MD Dept of Pediatrics, Johns Hopkins University School of Medicine, Baltimore, MD, USA. Over the past half century, chronic fatigue has been described as a prominent symptom in a variety of syndromes of orthostatic intolerance. These overlapping syndromes have been variously termed neurally mediated (or vaso-vagal) hypotension, delayed orthostatic hypotension, postural orthostatic tachycardia syndrome, and idiopathic hypovolemia. Perhaps the first suggestion that these abnormalities were responsible for symptoms of what we now call chronic fatigue syndrome (CFS) was made in 1940 by MacLean and Allen. These authors described a syndrome of excessive elevation in heart rate with upright posture seemed identical to "effort syndrome, irritable heart or neurocirculatory asthenia" (JAMA 1940;115:2162-7). They recommended treatment with up to 14g of sodium per day and sleeping in a head-up position. Recent work in our center and others has emphasized a high prevalence of neurally mediated hypotension (NMH), and less commonly postural orthostatic tachycardia syndrome, in those with an established diagnosis of CFS. In a 1995 study of 23 adolescents and adults with CFS, we identified hypotension in response to a three stage 70 degree upright tilt table test in 96% of patients, versus 29% of healthy controls. During the first 45 minutes of upright tilt, 16 patients (or 70%) with CFS developed hypotension, while all controls maintained a normal blood pressure.Perhaps more importantly, all 23 with CFS but none of the controls developed orthostatic symptoms during this first stage of tilt testing, suggesting that orthostatic intolerance may be a defining feature of the illness.

Extractions: Hi, I have been using this site for almost two years, finding it while attempting to get answers regarding an onset of palpitations, dizziness, fatigue, near syncope, etc. After the usual array of tests I was told I had bileaflet mitral valve prolapse of a moderate degree and 2+ regurgitation. I am no longer fearful of every heartbeat and have learned to cope with the days of relentless skips. I have found this site to be very helpful, reassuring, and a place I would come to almost everyday just to read the posts and know I was not alone when all this first started. Thank you to the doctors who provide insight with their knowledge, and to the many who post comments, like Hankstar,Arthur,Deb, who truly show they care and have great information to share.
Orthrostatic Tachycardia postural orthostatic tachycardia syndrome (POTS) is a form of autonomic dysfunctionthat presents with symptoms of postural tachycardia and lightheadedness, http://www.medhelp.org/forums/cardio/messages/32763.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. Postural orthostatic tachycardia syndrome (POTS) is a form of autonomic dysfunction that presents with symptoms of postural tachycardia and lightheadedness, disabling fatigue, exercise intolerance, dizziness, and near syncope. During baseline tilt table testing patients demonstrate a heart rate increase of > or = 30 beats/min (or a maximum heart rate of 120 beats/min) within the first 10 minutes upright (unassociated with profound hypotension), which reproduction of their symptom complex. In addition these patients exhibit an exaggerated response to isoproterenol infusions. Treatment may include lifestyle changes and/or medications such as beta-blockers. We have a specialist here in the area of autonomic function that deals with this condition. If you would like to be seen at the Cleveland Clinic call the number below and ask to make an appointment with Dr. Fouad in the syncope clinic.
