Prolonged Atrio-Ventricular Block Following Scorpion Bite: A Case Report

This report describes a 55-year-old woman in whom yellow scorpion sting resulted in the development of Mobitz type 1 and transient complete heart blocks unresponsive to atropine administration.  It might be concluded that although autonomic involvement including parasympathetic overactivity is present in such cases, other factors such as toxic damage to the cardiac conduction system may play a ...

Ventriculo-atrial gradient due to first degree atrio-ventricular block: a case report

BACKGROUND Isolated, asymptomatic first degree AV block with narrow QRS has not prognostic significance and is not usually treated with pacemaker implantation. In some cases, yet, loss of AV synchrony because of a marked prolongation of the PR interval may cause important hemodynamic alterations, with subsequent symptoms of heart failure. Indeed, AV synchrony is crucial when atrial systole, the...

Fournier’s gangrene following an ant bite in a healthy man: A very rare case report

Objective: Necrotizing fasciitis of the perinea, referred to as Fournier’s gangrene, is a necrotizing infection of the perinea. To the best of our knowledge, there is no report on the Fournier’s gangrene following an ant bite and this is a rare case report of this type.Case Presentation: In this rare case report we describe a 20-year-old man who developed Fournier’s gangrene following an ...

[Paroxysmal atrial tachycardia with atrio-ventricular block].

PAROXYSMAL atrial tachyeardia with atrioventricular block (PAT with block) has been recognized more often in recent years since Lown and Levine clarified its diagnostic criteria and emphasized its important relation to digitalis excess.1' 2 The present report was prompted by the increasing frequency with which this diagnosis has been made at our hospital and its common association with chronic ...

Atrio-ventricular conduction following radiofrequency ablation for atrio-ventricular node reentry tachycardia in children.

AIMS The study was designed to assess atrio-ventricular (AV) conduction with non-invasive methods at least 1 year after radiofrequency ablation (RFA) of the slow pathway for AV node reentry tachycardia. METHODS AND RESULTS Medical records of all patients who underwent RFA before their 18th birthday were reviewed. Patients were brought back for clinical evaluation, an electrocardiogram, an exe...
