Cooccurrence of Postural Orthostatic Tachycardia Syndrome with Two Different Clinical Entities

Case Reports in Pediatrics, 2016
Postural orthostatic tachycardia syndrome (POTS) is an abnormal heart rate response to a positional change. Several potential mechanisms for pathophysiology of POTS are defined. This syndrome can coexist with different clinical situations. In our report,

Etiological diagnosis, prognostic significance and role of electrophysiological study in patients with Brugada ECG and syncope. [PDF]

, 2017
BACKGROUND: Syncope is considered a risk factor for life-threatening arrhythmias in Brugada patients. Distinguishing a benign syncope from one due to ventricular arrhythmias is often difficult, unless an ECG is recorded during the episode.

From Postural Orthostatic Tachycardia Syndrome to Radiologically Isolated Syndrome

Case Reports in Neurological Medicine, 2018
Background. Autonomic dysfunction is common in Multiple Sclerosis (MS) patients. Most spinal cord lesions entail some degree of autonomic nervous system dysfunction. MS patients may develop autonomic dysfunction later in their disease course. Methods. We

Neuronal and hormonal perturbations in postural tachycardia syndrome

Frontiers in Physiology, 2014
The Postural Tachycardia Syndrome (POTS) is the most common disorder seen in autonomic clinics. Cardinal hemodynamic feature of this chronic and debilitating disorder of orthostatic tolerance is an exaggerated orthostatic tachycardia (≥30 bpm increase in

Postural Hyperventilation as a Cause of Postural Tachycardia Syndrome: Increased Systemic Vascular Resistance and Decreased Cardiac Output When Upright in All Postural Tachycardia Syndrome Variants

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Postural tachycardia syndrome (POTS) is a heterogeneous condition. We stratified patients previously evaluated for POTS on the basis of supine resting cardiac output (CO) or with the complaint of platypnea or “shortness of breath” during ...

Human leukocyte antigen associations in postural tachycardia syndrome

Annals of Clinical and Translational Neurology, 2019
Associations between human leukocyte antigen (HLA) and postural orthostatic tachycardia syndrome (POTS) have not been investigated. We included patients diagnosed with POTS and showing orthostatic heart rate increases ≥ 50 during orthostatic vital sign ...
