Heart rate variability analysis in postural orthostatic tachycardia syndrome: a case report

Postural tachycardia syndrome (PoTS) is a chronic condition, predominately affecting women between the ages of 15 and 50, and prevalence is estimated to be 0.2%.1,2 It is characterised by an abnormal response by the autonomic nervous system to changes in posture causing lightheadedness ...

Vasovagal syncope (VVS), the most common cause of fainting, is predominantly caused by an overactive vagal tone, leading to asystole, sinus bradycardia, or atrioventricular block.1 This condition, a form of neurocardiogenic syncope, is characterized by a pronounced vagal reflex that ...

The Leiden University Medical Centre, Netherlands, has been recognized worldwide as a Center of Excellence for syncope, a common and yet all too often misdiagnosed symptom. Roland Thijs has received this prestigious award in recognition of its pioneering work for ...

Vasovagal syncope is common, and while it is usually associated with a benign prognosis, it results in significant physical and psychological morbidity for affected individuals. Despite comprehensive understanding of the underlying pathophysiology, there have been few definitive therapeutic advances until ...

Psychogenic nonepileptic seizures (PNES), or pseudoseizures, are paroxysmal episodes that resemble, and often misdiagnosed as, epileptic seizures; however, they are psychological (i.e., emotional, stress-related) in origin. Unlike epileptic seizures, PNES do not result from an abnormal electrical discharge from ...

Introduction: This review examines the current literature and guidance relating to syncope in the trauma patient, exploring the causes of syncopal falls that may be overlooked, and discussing the optimal evaluation and safe management of syncope patients. Discussion: Overall, 42% of ...

Aims: Previous studies have evaluated the incidence and prognostic significance of syncope in ICD recipients; however, these have been almost exclusively derived from randomised controlled trials (RCTs) of primary prevention patients with severe left ventricular systolic dysfunction (LVSD). There is ...

Background: About 25% of the population suffers from syncope, and 8% of the population experience recurrent episodes, which can cause physical injury and psychological morbidity. Methods: We performed a meta-analysis of randomised trials of pacing, pharmacological and physical interventions for syncope. We ...

Introduction: The Syncope Service has been running for a decade and is the only clinic to offer beat-to-beat plethysmography in Addenbrooke’s Hospital. An increasing number of younger patients have been referred to the clinic with suspected postural orthostatic tachycardia ...
