Z USAMMENFASSUNG Hintergrund: Diagnostik und Therapie: Med Klin 2000;95:442–6. A BSTRACT Postural Orthostatic Tachycardia Syndrome (POTS): Pathogenesis, Diagnostic Evaluation, and Therapeutic Options Background: Since the renaissance of tilt table testing in clinical cardiology some 15 years ago, the syndromes of autonomic dysfunction with orthostatic intolerance underwent improved differentiation and classification. In the present review a variant of autonomic dysfunction with orthostatic intolerance – POTS (postural orthostatic tachycardia syndrome) – will be discussed. Diagnosis and Treatment: The affected patients present with orthostatic intolerance, postural tachycardia, exercise intolerance, fatigue, dizziness and in some cases with other dysautonomic symptoms such as gastrointestinal or sudomotor dysfunction. Together with the clinical history, tilt table testing is the cornerstone of diagnostic evaluation by which the syndrome can be distinguished from typical neurocardiogenic disorders. POTS is characterized by

    An increase in heart rate of 28 beats per minute (bpm) OR a pulse of more than 110120bpm is known as postural orthostatic tachycardia syndrome (POTS) happens
    http://www.bioterrain.co.uk/BioTerrain/bp.html
    Blood Pressure Monitoring The Orthostatic Blood Pressure Test shows us how well your body adapts to standing up after having been lying down for 10 minutes. When lying down your blood vessels are relaxed and dilated, when you get up they must contract as otherwise all your blood 'would sit around your ankles with nothing in your head'. Actually venous pooling concerns mainly the large abdominal vessels. Among the chemicals released by the Autonomic Nervous System to control the circulating blood volume are cortisol, dopamine, epinephrine (adrenaline), and norepinephrine (very similar to epinephrine but with somewhat less effect on the heart). The organ crucial to this happening is the adrenal gland and principal hormones produced by its adrenal cortex are cortisol (hydrocortisone), aldosterone, and dehydroepiandrosterone (DHEA). Adults secrete about 20 mg of cortisol, 2 mg of corticosterone (which has similar activity), and 0.2 mg of aldosterone daily. Although considerable quantities of androgens (primarily DHEA and androstenedione) are normally produced by the adrenal cortex, their chief physiologic activity occurs only after conversion to testosterone and dihydrotestosterone. The orthostatic blood pressure test (10 minutes supine and upto 30 minutes standing) thus gives an insight into the functionality of the patient's adrenal gland. In a healthy subject the BP may temporarily rise slightly or remain constant as will the pulse rate; in a patient with poor adrenal functioning the BP will drop. The Orthostatic Blood Pressure Test is correlated to the U1 / U2 resistance of Biological Terrain Analysis as well as to the Heart Rate Variability study which is another, ECG based orthostatic test, and laboratory tests. Some BP irregularities that can occur alone or as combinations:

    Previous Next Vasovagal Syncope and Related Disorders The management of patients in whom a primary abnormality in blood pressure regulation results in hypotension and loss of consciousness presents clinical challenges. The hypotension may be primary, or it may be secondary to a condition such as tachyarrhythmia or bradyarrhythmia. Vasovagal syncope describes this condition, as well as other conditions that are considered to be dysautonomic responses to upright posture, such as orthostatic hypotension and postural orthostatic tachycardia syndrome (POTS). Bloomfield and associates reviewed the pathophysiology of these two causes of syncope and developed an algorithm to guide diagnosis and treatment. see the accompanying figure on page 2212

    Cardiac Arrhythmia Management: Why Women are Different from Men
    Electrical Explanation For Gender Differences
    The fact that women's hearts are wired differently from men's should come as no surprise. The development of every part of the body is determined genetically, and modified by the sex hormones. The fact that we develop so similarly should really surprise us. This is also true of the electrical system of the heart in women. The way that the heart works isthrough an electrical system that we can measure on the surface with the electrocardiogram (ECG). This detects the electrical activity of the top chambers of the heart, the atria, manifest by a p wave, followed by a sharp deflection, the QRS, which represents the electrical activity of the ventricles of the heart. Following the QRS, there is a recovery interval, marked on the ECG by a hump, and the distance between the beginning of the QRS and the end of this hump, the T wave, is called the QT interval. The electrical activity we see on the surface is created by the sequential, and sometimes simultaneous, activity of a number of channels in the muscle membranes of heart tissue to allow certain ions, such a sodium, calcium, potassium, and some chemicals, such as acetylcholine, and ATP (an energy molecule) to cross into or out of the cell. The structure of these channels is determined genetically, and to some degree, their genetic expression varies with gender.

    DR. BELL'S NEW RESEARCH BASED THEORIES
    By Gail Kansky

    A slide was shown to an appreciative audience of a cartoon where a doctor
    is saying to the patient, You have a serious disease of undetermined nature.
    Although the cartoon has been used for many years, David S. Bell, M.D., world
    known pediatric and adult CFIDS specialist said, "This is what we're still
    dealing with."
    Although the symptoms all appear to be connected, they will "from week to
    week frequently change," said Dr. Bell. In his first 100 patients he saw, only
    49% had fatigue as the dominant symptom yet a high 97% of the children and
    92% of the adults had neurological symptoms. Doctors "invariably give the wrong first diagnosis. They think they're helping by being decisive but this has only caused heartache in this illness." Dr. Bell mentioned that he had "lot of problems with the criteria that the CDC put out in 1994. Indeed, the restriction degree is possible.

    Patient Questions, April 1999
    This Web page is designed for the general education of patients and their families. Dr. Tom Chelimsky . No patient should make any changes in their care without first consulting their physician.
    Question 1: I have postural orthostatic tachycardia. What other disorders can this be associated with? I am taking Flurinef, which helps with the lightheadness but I am still extememly fatiuged and brain fogged. Any suggestions? Dr. Chelimsky: Postural orthostatic tachycardia syndrome (POTS) is quite common in and of itself. It usually occurs after a viral syndrome ("flu") but may occur without any heralding event, or may also be inherited (check to see if you have relatives with milder similar symptoms). If there is an autonomic laboratory near where you live, it is best if the diagnosis can be confirmed by this type of testing (usually a heart nerve check, and a sweat nerve check of some type), and damage to the nerves can be excluded. This diagnosis is a SYNDROME, not a disease, and there are probably many types of diseases that lead to this set of symptoms. Depending on the reasons that the symptoms are there, the treatment would vary. If the veins are not returning blood to the heart, you need more salt loading (you should eat lots and lots of salt each day, aiming for 15 g per day). If the arteries are not constricting properly, a drug called midodrine may be helpful. Walking in the water and thigh strengthening exercises may be quite helpful in reconditioning you regardless of the cause of the problem.

The Autonomic Laboratory at University Hospitals of Cleveland is the only facility of its kind in Ohio and surrounding states. Using state-of-the-art equipment, the lab offers non-invasive testing that evaluates abnormalities in the control of blood pressure, heart rate, urination, digestion, sexual function, and sweating. Testing, intended for patients over the age of 1, helps to diagnose a wide variety of autonomic disorders, enabling the referring physician to provide appropriate and specific treatment.
    Assessment of symptoms
    Autonomic testing will accurately and reliably establish whether the autonomic nervous system is the cause of any of the symptoms below: Syncope is due to an abnormality of the autonomic nervous system in 75 percent of patients who do not have obvious heart disease or a seizure disorder. Radicular thoracic and abdominal pain are common in diabetics or may be caused by infectious (herpes zoster) or mechanical (intervertebral disk herniation) processes. The sweat test confirms the diagnosis of radiculopathy by revealing a failure to sweat in the involved dermatome. Sexual dysfunction may be the initial manifestation of disorders affecting much of the autonomic nervous system. Autonomic function tests can directly estimate the extent of involvement of the sympathetic and parasympathetic nervous systems. This is especially important in evaluating diabetics and other patients with erectile dysfunction who may have both organic and psychogenic etiologies.

A pathologically slow recovery period (it takes more than 24 hours to recover). Symptoms exacerbated by stress of any kind. Patient must have a marked degree of new onset, unexplained, persistent, or recurrent physical and mental fatigue that substantially reduces activity level. [Editor’s note: The M.E. Society prefers to use “delayed recovery of muscle function,” weakness, and faintness rather than “fatigue.” Further, we disagree that the muscle dysfunction is “unexplained.” See our M.E. Definitional Framework and researchers’ medical explanations on this website.]
