Background: To evaluate the usefulness of the Holter method of sinoatrial conduction time (SACT) calculation in predicting the future occurrence of sinus node disease, and the emergence of indications for permanent pacing in patients with unexplained syncope. Methods: The study group included 218 patients (mean age 55 ± 17 years, 116 men) with syncope of unknown etiology in whom spontaneous atr...

background: recent evidences have supported migraine headache and neurally mediated syncope as the especial types of endotheliopathies. to determine endothelial function in patients with migraine headache or those with neurally mediated syncope,the present study was conducted. materials and methods: this cross-sectional study was performed on 93 consecutive patients aged 5-20 years in four grou...

Abstract Background COronaVIrus Disease 19 (COVID-19) pandemic is a global health emergency. Since the first reported cases in Asia, virus has now spread worldwide. Given its high contagiousness, one of greatest challenges early detection infected patients. People affected by COVID-19 have had wide range presenting symptoms, from very mild to severe, including fever, cough, shortness breath, ga...

A 62-year-old man presented to the emergency department with an episode of syncope after 2-3 weeks of diffuse abdominal pain, now complaining of a severe increase in pain concurrent with >24 hours of no urine output. His workup showed an idiopathic extraperitoneal rupture of the bladder on computed tomography, which was handled conservatively with Foley insertion. Repeated follow-up and imaging...

In clinical practice, upright tilt testing is frequently used to determine the etiology of syncope by trying to induce vasovagal reactions. The importance of the test is underscored by the fact that before the introduction of the test in 1986 by Kenny et al.,1 often expensive cardiac examinations were performed without resulting in a clear diagnosis. The more frequent use of the “passive” unmed...

normal 0 false false false en-us x-none ar-sa carotid body tumor (cbt) is paraganglioma and mainly found in the carotid bifurcation. the manifestations of the tumor are variable; in most cases, it presents as a non-symptomatic slow-growing mass, rarely compression of carotid body induces bradycardia and hypotension and repeated syncope, prolonged syncope can cause convulsion. convulsive syncope...

Tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC) are more frequently being recognized as the etiology of multiple types of respiratory complaints from chronic cough to exertional syncope to recurrent infections. Identification of these conditions requires a high suspicion, as well as a thorough history and physical examination. Dynamic computed tomography imaging and bro...

Background: Insufficiency of the internal jugular valve is a scarcely found etiology in literature for cough headache, which can be associated with other vascular disorders. The objective this study to report through clinical and imaging findings rarely described association between headache insufficiency. Cases: Two male patients, ages 79 70-year-old respectively, were evaluated episodes Valsa...

This report describes a new etiology of pediatric syncope. Epilepsy, brain anomalies, infection, electrolyte abnormalities, and trauma are commonly identified etiologies of seizures in the pediatric population. We report here a child with third-degree heart block and right ventricular outflow tract obstruction related to an intracardiac tumor presenting with syncope and seizure-like activity. E...
