Chapters at Harrison's ABSTRACT Background The postural tachycardia syndrome is a common disorder that is characterized by chronic orthostatic symptoms and a dramatic increase in heart rate on standing, but that does not involve orthostatic hypotension. Several lines of evidence indicate that this disorder may result from sympathetic denervation of the legs. Methods We measured norepinephrine spillover (the rate of entry of norepinephrine into the venous circulation) in the arms and legs both before and in response to exposure to three stimuli (the cold pressor test, sodium nitroprusside infusion, and tyramine

RF - REVIEW ARTICLE: 48 REFS. AD - Department of Neurology, Mayo Clinic, Rochester, MN 55905, USA. AB - In orthostatic intolerance, the patient develops symptoms while standing that are relieved when the patient assumes a supine position. Different degrees of orthostatic intolerance exist, but not a system of grading severity. We have developed a system that grades the severity of orthostatic intolerance by the three-pronged criteria of the rapidity of development and the severity of orthostatic symptoms, the ability of the subject to withstand orthostatic stresses, and the degree of interference with daily living. In this article, this system is presented, and one disorder, postural tachycardia syndrome (POTS), is examined

ORTHOSTATIC HYPOTENSION Timothy C. Hain, MD. Please read our Return to Index Search this site Page last modified: February 2, 2004 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. Vertigo and orthostatis may co-exist however. Symptoms that often accompany orthostatic hypotension include chest pain, trouble holding the urine, impotence, and dry skin from loss of sweating. What Causes Orthostatic Hypotension ? 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.

Definitions History Symptoms ... Prognosis Definitions It is estimated that over 500,000 Americans are afflicted with Orthostatic Intolerance. Despite the enormity of the number, these conditions are among the least understood of the autonomic disorders. Affecting predominately younger individuals, often in those under the age of thirty five, these syndromes affect more women than men. The onset can be sudden, and the impact can be significant on both lifestyle and on the capacity to work. Often, these conditions tend to be misdiagnosed as either a psychiatric or anxiety - related disorders, due to the nature of the symptoms. Standing upright results in a series of reflexive bodily responses, regulated by the Autonomic Nervous System , to compensate for the effect of gravity upon the distribution of blood. These conditions are a result of an inappropriate response to this change in body position.

90. ORTHOSTATIC INTOLERANCE two, systematic orthostatic tachycardia (SOTS) and postural orthostatic tachycardia (POTS), are malfunction is taking place in all three orthostatic syndromes. http://www.geocities.com/HotSprings/5983/orthostatic.htm

ORTHOSTATIC INTOLERANCE A common increase in the severity of symptoms often occurs in PWC's while standing. According to a study by Dr. Lapp there are 4 responses to the tilt table test / standing up without movement. The most commonly know is neuro mediated hypotenstion (NMH), which is characterized by a sudden drop in blood pressure and heart rate accompanied by the symptoms of dizzyness, nausea, weakness, fainting and sweating. The next two, systematic orthostatic tachycardia (SOTS) and postural orthostatic tachycardia (POTS), are related with a increase in heart rate above normal, palpitations and the symptoms of nausea, sweating , dizzyness, and headache. They differ in the amount of time before increased symptoms (sots= 10 min , pots=5 min). The last response is that of a typical healthy individual Rescently allot of press has been given to neuro mediated hypotention, but a study has reported a higher incidence of SOTS (at 28%) compared to NMH (at 24%) in the CFIDS population. (48% had a healthy response to standing) It seems that a common system malfunction is taking place in all three orthostatic syndromes. Researchers speculate that PWC's have low blood volume and pooling of the blood in the legs. Possible reasons for this abnormality could stem from miscommunication between the heart and the brain or damage to the long nerves responsible for blood vessel contriction. It is also assumed that low blood volume contibutes to cardiac abnormalities because of the reduced amount of blood in the heart.

Dysautonomia Postural Orthostatic Tachycardia Syndrome Music: Beethoven: 9 Symphonien Music: Music: Beethoven for Babies: Brain Training for Little Ones - This is a very pleasant CD to listen to, and I think the quality of the music is excellent. I enjoy listening to this with my 10 month old son, and we also listen to the radio and lots of modern music. I recently purchased 5 of the classical "Baby Einstein" CDs and I consider them to be inferior to this Beethoven for Babies CD. The Baby Einstein are very synthesized sounding and I think they are annoyingly mellow and kind of dopey. This Beethoven CD is beautiful. In fact I'm going to buy 1 or 2 more from this series. Music: Stockholm Syndrome - Ok Backyard Babies have not put out a bad CD yet and this proves it this CD is awsome. I listen to it all the time it's spinning in my stereo right now. This just proves that America can't do music right so we have to count on Sweden. Also the song Friends is amazing it is one of the coolest songs ever. So get this CD and if you like them check out Hardcore Superstar another awsome Swedish band.
