We report the case of a 14-year-old girl who developed postural orthostatic tachycardia syndrome (POTS) with chronic fatigue 2 months following Gardasil vaccination. The patient suffered from persistent headaches, dizziness, recurrent syncope, poor motor coordination, weakness, fatigue, myalgias,
BACKGROUND
Orthostatic hypotension during upright tilt is an important physical disorder in patients with chronic fatigue syndrome. We have tested its occurrence during prolonged standing, whether it is correctable, and whether reduced circulating erythrocyte volume is present.
METHODS
Fifteen
OBJECTIVE
A significant proportion of patients with chronic fatigue syndrome (CFS) also have postural orthostatic tachycardia syndrome (POTS). We aimed to characterize these patients and differentiate them from CFS patients without POTS in terms of clinical and autonomic features.
METHODS
A total of
BACKGROUND
Transfusion guidelines recommend that clinicians assess patients for signs and symptoms of anemia before the transfusion of RBCs. However, studies of signs and symptoms associated with acute isovolemic anemia are limited. The objective of this study was to determine whether acute
BACKGROUND
A subgroup of patients suffering from Lyme disease (LD) may initially respond to antibiotics only to later develop a syndrome of fatigue, joint pain and cognitive dysfunction referred to as 'post treatment LD syndrome'. We report on a series of patients who developed autonomic dysfunction
Upright posture imposes a substantial gravitational stress on the body, for which we are able to compensate, in large part because of the autonomic nervous system. Alteration in autonomic function, therefore, may lead to orthostatic intolerance. On one extreme, patients with autonomic failure caused
Autonomic nervous system (ANS) dysfunction has been suggested in patients with chronic fatigue syndrome (CFS). In this study, we sought to determine whether increased heart rate (HR) and reduced heart rate variability (HRV) parameters observed in CFS patients during wakefulness persist during sleep.
The aim of the study was to investigate the effect of catheter ablation on different aspects of health-related quality of life in association with patients' age, gender and the type of paroxysmal supraventricular tachycardia. We investigated 70 consecutive patients with paroxysmal supraventricular
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
Postural tachycardia syndrome (POTS) is the combination of an exaggerated heart rate response to standing, in association with symptoms of lightheadedness or pre-syncope that improve when recumbent. The condition is often associated with fatigue and brain fog, resulting in significant disruptions at
Inappropriate sinus tachycardia is defined as sinus tachycardia at rest (heart rate ≥100 bpm) in sitting position or/and as an average heart rate ≥90 bpm during 24-hour Holter monitoring. The most common symptoms are palpitation, dizziness, chest discomfort, orthostatic intolerance, and fatigue.
OBJECTIVE
To report a case of symptomatic tachycardia that was successfully treated with propranolol in a patient receiving duloxetine.
METHODS
A 26-year-old man presented with episodes of fatigue, tachycardia, diaphoresis, and chest pain approximately 2 months after the initiation of duloxetine 20
BACKGROUND
Pre-excitation is based on an accessory conduction pathway between the atrium and ventricle. The term Wolff-Parkinson-White (WPW) syndrome is used for patients with the pre-excitation/WPW pattern associated with AP-related tachycardia.
METHODS
We present a 52-year-old man with severe
A 12-year-old girl with symptoms of fatigue, decreased exercise tolerance and progressive dyspnea (New York Heart Association functional class III) with a possible diagnosis of dilated cardiomyopathy secondary to viral myocarditis. Because of incessant wide QRS tachycardia refractory to
We experienced a man in his 20s with inappropriate sinus tachycardia (IST) initially diagnosed and treated as depression who was steadily treated with radiofrequency catheter ablation (RFCA) using an EnSite™ system. The patient has remained well without any symptoms or medications, including
