• #1 Postural Orthostatic Tachycardia Syndrome Symptoms, and Treatments

  https://www.upmc.com/services/heart-vascular/conditions/postural-orthostatic-tachycardia-syndrome

  Postural orthostatic tachycardia syndrome, commonly called POTS, is a blood circulation disorder. It causes a rapid heart rate when moving from a seated to a standing position. […] This increase in heart rate may be uncomfortable and, upon standing, can cause: Dizziness, Lightheadedness, Fainting. […] When POTS symptoms are severe, they can impact your quality of life. […] POTS is an abnormal response to your ANS, causing most of your blood to stay in your lower body when you stand. […] With POTS, this malfunction in the ANS can cause: A fast heart rate, A drop in blood pressure, Lightheadedness, dizziness, or fainting. […] These symptoms occur because your heart must beat even faster to get blood to the brain and rest of the body. […] POTS causes a range of symptoms that can vary from person to person.

  The evolution of upright posture is usually considered an advantage in humans. For people with postural tachycardia syndrome (PoTS) it can present a daily challenge. Although orthostatic intolerance is often associated with older people, PoTS tends to affect young women who present with multiple, non-specific symptoms and significant functional impairment. […] […] PoTS tends to affect people aged 15-50 years and is four times more common in females. This may relate to peripheral vasodilator effects of female sex hormones and vasoconstrictive effects of testosterone. The prevalence in the UK is unknown but probably under-estimated due to overlap with other pathologies such as chronic fatigue, post-viral syndromes, and limited availability of knowledgeable healthcare personnel. […] […] A plethora of symptoms are thought to result from hypoperfusion and compensatory increased catecholamine levels. Many patients experience light-headedness, but 41.4% have transient loss of consciousness. Symptoms tend to be worse on standing or prolonged sitting and exacerbated by heat, food, and alcohol. Life expectancy is thought to be unaffected, but disability is considerable and equivalent to that found in congestive heart failure and chronic obstructive pulmonary disease. […]

  https://en.wikipedia.org/wiki/Postural_orthostatic_tachycardia_syndrome

  Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea, difficulty concentrating, tremulousness (shaking), syncope (fainting), coldness, pain, or numbness in the extremities, chest pain, and shortness of breath. Many symptoms are exacerbated with postural changes, especially standing up. […] In adults, the primary manifestation is an increase in heart rate of more than 30 beats per minute within ten minutes of standing up. The resulting heart rate is typically more than 120 beats per minute. For people between ages 12 and 19, the minimum increase for a POTS diagnosis is 40 beats per minute. POTS is often accompanied by common features of orthostatic intolerance in which symptoms that develop while upright are relieved by reclining. These orthostatic symptoms include palpitations, light-headedness, chest discomfort, shortness of breath, nausea, weakness or „heaviness” in the lower legs, blurred vision, and cognitive difficulties. Symptoms may be exacerbated with prolonged sitting, prolonged standing, alcohol, heat, exercise, or eating a large meal.

  POTS is defined as the presence of chronic symptoms of orthostatic intolerance (6 months) accompanied by an increased heart rate (HR) 30 bpm within 10 minutes of assuming an upright posture and in the absence of orthostatic hypotension (blood pressure [BP] fall 20/10 mmHg). […] Both cardiac symptoms (rapid palpitation, lightheadedness, dyspnea and chest discomfort) and non-cardiac symptoms (headache [often migraines], tremulousness, nausea, sleep difficulties, mental clouding [probably due to diminished attention and not necessarily memory problems], exercise intolerance and chronic fatigue) are often present. […] The overwhelming majority of patients with POTS are women (80-85%) of child-bearing age (13-50 years). […] Patients frequently report that their symptoms began following acute stressors (e.g., presumed viral illness, major surgery, injury, or pregnancy) but symptoms may also develop more insidiously.

  POTS is a multifactorial syndrome rather than a specific disease. It is characterized by all of the following: An increase in heart rate of 30 bpm, or 40 bpm for those under age 19, within 10 minutes of standing from a supine position; Sustained tachycardia (30 seconds); Absence of orthostatic hypotension (a fall in blood pressure of 20/10 mm Hg); Frequent and chronic duration (6 months). These features are critical to diagnosis. […] The prevalence of POTS is estimated to be between 0.2% and 1.0%, affecting up to 3 million people in the United States. Most cases arise between ages 13 and 50, with a female-to-male ratio of 5:1. […] Up to 70% of patients with POTS have hypovolemia. The average plasma volume deficit is about 13%, which typically causes only insignificant changes in heart rate and norepinephrine levels while a patient is supine. However, blood pooling associated with upright posture further compromises cardiac output and consequently increases sympathetic nerve activity.

  https://newsnetwork.mayoclinic.org/discussion/mayo-clinic-q-and-a-all-about-pots-postural-tachycardia-syndrome/

  Postural tachycardia syndrome affects the autonomic nervous system, which controls involuntary body functions such as heart rate and blood pressure. In postural tachycardia syndrome, the nerves that regulate blood flow are out of balance, so enough blood doesn’t go to the right place at the right time. The result is a variety of symptoms, including an overly rapid heartbeat when shifting from lying down to standing up. […] Other postural tachycardia syndrome symptoms may include chronic fatigue; headaches or other types of chronic pain; and digestive problems, such as nausea and cramping. These symptoms may vary considerably from one person to another. […] Postural tachycardia syndrome begins in the teenage or early adulthood years. Although postural tachycardia syndrome is a chronic condition, about 80 percent of patients grow out of it. Until that happens, treatment can ease postural tachycardia syndrome symptoms.

  Primary PoTS is often of abrupt onset and may follow pregnancy, surgery, immunisation, or trauma. There is some evidence of autoimmune aetiology. Many cases follow viral infections and these are more likely to be self-limiting. A developmental form of primary PoTS affects teenagers (gradual onset around age 14 years) and 80% resolve within a few years. A genetic defect has been identified in some patients with the hyperadrenergic form of PoTS. […] […] As a result of orthostatic intolerance, patients can become wheelchair users or bed-bound and are often unable to continue in education or employment (25%). However, 80-90% will respond to treatment and 60% will return to previous levels of functioning. […] A diagnosis of PoTS should be considered in patients (especially young women) with a combination of unexplained symptoms. The most common are dizziness, palpitations, and tiredness which are usually worse with upright posture.

  Forms of cardiac dysautonomia associated with long COVID include postural orthostatic tachycardia syndrome (POTS), orthostatic intolerance, vasovagal reflex susceptibility, and hypotension. POTS affects approximately 30% of highly symptomatic patients with long COVID. Symptoms of POTS and other forms of cardiac dysautonomia include palpitations, orthostatic symptoms, fatigue, brain fog, sleep disturbance, migraine, and muscle weakness, among others. […] Interestingly, symptoms of POTS may be seen at the time of acute COVID infection and persist despite resolution of acute COVID or present for the first time months after the initial infection. […] The prognosis of dysautonomia in patients with long COVID is not well understood. A significant number of patients have been shown to spontaneously recover within 12 months; however, because the symptoms may be quite disruptive to work and quality of life, it is worth continuing to study ways to accelerate healing or relief of symptoms in patients with this condition.

  POTS is part of a group of disorders that feature orthostatic intolerance. The classic symptom of POTS is a fast heartbeat. A person’s heart rate may increase by more than 30 beats per minute or exceed 120 beats per minute within 10 minutes of standing. POTS can also cause lightheadedness or dizziness, fainting, and palpitations which often occur upon standing. POTS may also cause exhaustion, headaches, and other symptoms. Some people may have blurred vision or tunnel vision, weakness in the legs, chest pain or other pain, fatigue, sleep problems, digestive issues, shortness of breath, and difficulty concentrating. POTS symptoms may come and go over time (called relapsing-remitting pattern). In most cases, POTS symptoms improve over time, though some symptoms may remain or last a long time.

  Postural orthostatic tachycardia syndrome (POTS) is one of a group of disorders that have orthostatic intolerance (OI) as their primary symptom. The primary symptom of OI is lightheadedness or fainting. In POTS, the lightheadedness or fainting is also accompanied by a rapid increase in heartbeat of more than 30 beats per minute, or a heart rate that exceeds 120 beats per minute, within 10 minutes of rising. The faintness or lightheadedness of POTS are relieved by lying down again. POTS often begins after a pregnancy, major surgery, trauma, or a viral illness. It may make individuals unable to exercise because the activity brings on fainting spells or dizziness. POTS may follow a relapsing-remitting course, in which symptoms come and go, for years. In most cases (approximately 80 percent), an individual with POTS improves and becomes functional, although some residual symptoms are common.

[…] The main POTS subtypes are Hyperadrenergic POTS, Neuropathic POTS, Hypovolemic POTS, and immune-mediated or autoimmune POTS. Hyperadrenergic POTS can be characterized by excessive tachycardia upon standing, an increase in systolic blood pressure of more than 10 mmHG, and elevated standing norepinephrine levels of 600 pg/mL or more.

  About half of patients with POTS have partial sympathetic denervation (particularly in the lower limbs) and inadequate vasoconstriction upon standing, leading to reduced venous return and stroke volume. A compensatory increase in sympathetic tone results in tachycardia to maintain cardiac output and blood pressure. […] Up to 50% of patients with POTS have high norepinephrine levels (600 pg/mL) when upright. This subtype, hyperadrenergic POTS, is characterized by an increase in systolic blood pressure of at least 10 mm Hg within 10 minutes of standing, with concomitant tachycardia that can be similar to or greater than that seen in nonhyperadrenergic POTS.

  Partial dysautonomic (PD) POTS (also referred to as Neuropathic POTS) is the predominant form. This is a mild peripheral autonomic neuropathy, characterized by inadequate peripheral vasculature constriction in the face of orthostatic challenge. […] Developmental partial dysautonomic POTS is an adolescent subtype. The mean age of onset is 14 years. The clinical scenario is that of orthostatic intolerance following a period of very rapid growth. Symptoms are progressive and peak at a mean age of 16 years. Orthostatic intolerance may be severe, including severe headaches, and can be functionally disabling. Following their peak symptoms will slowly improve and resolve into young adulthood (19-24 years). Roughly 80% of patients with developmental PD POTS will experience complete resolution of symptoms.

  About half of patients with POTS have partial sympathetic denervation (particularly in the lower limbs) and inadequate vasoconstriction upon standing, leading to reduced venous return and stroke volume. A compensatory increase in sympathetic tone results in tachycardia to maintain cardiac output and blood pressure. […] Up to 50% of patients with POTS have high norepinephrine levels (600 pg/mL) when upright. This subtype, hyperadrenergic POTS, is characterized by an increase in systolic blood pressure of at least 10 mm Hg within 10 minutes of standing, with concomitant tachycardia that can be similar to or greater than that seen in nonhyperadrenergic POTS. Patients with hyperadrenergic POTS tend to report more prominent symptoms of sympathetic activation, such as palpitations, anxiety, and tremulousness.

  POTS is a multifactorial syndrome rather than a specific disease. It is characterized by all of the following: An increase in heart rate of 30 bpm, or 40 bpm for those under age 19, within 10 minutes of standing from a supine position; Sustained tachycardia (30 seconds); Absence of orthostatic hypotension (a fall in blood pressure of 20/10 mm Hg); Frequent and chronic duration (6 months). These features are critical to diagnosis. […] The prevalence of POTS is estimated to be between 0.2% and 1.0%, affecting up to 3 million people in the United States. Most cases arise between ages 13 and 50, with a female-to-male ratio of 5:1. […] Up to 70% of patients with POTS have hypovolemia. The average plasma volume deficit is about 13%, which typically causes only insignificant changes in heart rate and norepinephrine levels while a patient is supine. However, blood pooling associated with upright posture further compromises cardiac output and consequently increases sympathetic nerve activity.

  Some of the symptoms observed in POTS overlap with exercise deconditioning. For example, low exercise tolerance, high heart rate responses during submaximal exercise, and reduced stroke volume during exercise have been observed in POTS patients. […] In patients with hypovolemic POTS, management is centered around maintaining adequate intravascular volume. […] If symptoms persist through nonpharmacologic treatment, pharmacologic options are available. […] For hypovolemic POTS, fludrocortisone and desmopressin may help with symptom control. […] In dysautonomic POTS, medications are directed at increasing vascular tone to prevent blood pooling and subsequent orthostatic tachycardia. […] The treatment of POTS remains complex and, at times, difficult to execute as there are currently no long-term, multicenter randomized clinical trials to guide treatment.

  Orthostatic intolerance is the main characteristic of POTS, and can manifest as a variety of symptoms such as headache, dizziness, nausea, lightheadedness, blurred vision, palpitations, tremors, and difficulty concentrating. It has been reported that the degree of orthostatic HR increment is not directly correlated with clinical symptoms, probably due to the diurnal variability of orthostatic tachycardia. However, the severity of orthostatic intolerance symptoms is significantly correlated with depression and QOL. In particular, chest discomfort and difficulty concentrating are strongly associated with depression, and nausea and difficulty concentrating are associated with diminished QOL. […] The exact pathogenesis underlying POTS remains unknown. Several clinical characteristics support the possibility that POTS is an autoimmune disorder, such as female predominance, preceding viral illness, prior vaccination history, and coexistence of other autoimmune disorders, characteristics that are frequently reported in other autoimmune diseases. Therefore, it has been suggested that POTS should be considered a novel member of the family of autoimmune disorders.

  Forms of cardiac dysautonomia associated with long COVID include postural orthostatic tachycardia syndrome (POTS), orthostatic intolerance, vasovagal reflex susceptibility, and hypotension. POTS affects approximately 30% of highly symptomatic patients with long COVID. Symptoms of POTS and other forms of cardiac dysautonomia include palpitations, orthostatic symptoms, fatigue, brain fog, sleep disturbance, migraine, and muscle weakness, among others. […] Interestingly, symptoms of POTS may be seen at the time of acute COVID infection and persist despite resolution of acute COVID or present for the first time months after the initial infection. […] The prognosis of dysautonomia in patients with long COVID is not well understood. A significant number of patients have been shown to spontaneously recover within 12 months; however, because the symptoms may be quite disruptive to work and quality of life, it is worth continuing to study ways to accelerate healing or relief of symptoms in patients with this condition.

  Primary PoTS is often of abrupt onset and may follow pregnancy, surgery, immunisation, or trauma. There is some evidence of autoimmune aetiology. Many cases follow viral infections and these are more likely to be self-limiting. A developmental form of primary PoTS affects teenagers (gradual onset around age 14 years) and 80% resolve within a few years. A genetic defect has been identified in some patients with the hyperadrenergic form of PoTS.

  The main symptoms described were related to orthostatic intolerance and gastrointestinal function according to the COMPASS 31 (weighted score 27.52/40 and 9.37/25, respectively) and to orthostatic intolerance and visual acuity according to the VAS (score 5.82/10 and 4.56/10, respectively). […] The trend of symptoms seemed to remain substantially stable over the two years of observation. However, the patients did report a significant improvement over time, both in the overall symptomatic burden as well as in the perception of quality of life. […] The results of the present study suggest that, despite the progressive global clinical improvement over the two years of observation, none of the patients who were inactive at baseline resumed their previous working activities. This may indicate the lack of specific advice by the occupational physician in pointing out alternative job tasks that are more suitable for a patient suffering from a disease characterized by orthostatic intolerance.
