An asymptomatic 5-year-old girl presented with bradycardia during a routine well-child visit. Further evaluation revealed profound sinus bradycardia, exercise-induced bidirectional ventricular tachycardia, and supraventricular tachycardia. An echocardiogram showed heavy trabeculations in the left ventricular myocardium. This patient's presentation suggested catecholaminergic polymorphic ventric...

Cardiac arrhythmias are a recognized cause of transient alteration of consciousness and unless suspected, a cardiac aetiology for apparent neurological symptoms may be overlooked. We retrospectively assessed the variation in the investigations of 122 patients who were referred to our hospital over a twelve month period for assessment of transient alteration of consciousness and we attempted to ...

OBJECTIVE The aim of this study is to review the current management and outcomes of fetal bradycardia in 9 Spanish centers. METHODS Retrospective multicenter study: analysis of all fetuses with bradycardia diagnosed between January 2008 and September 2010. Underlying mechanisms of fetal bradyarrhythmias were studied with echocardiography. RESULTS A total of 37 cases were registered: 3 sinus...

We present a case of sinus node arrest leading to symptomatic junctional bradycardia from oral phenytoin toxicity, which is a rare presentation. Our patient had no prior cardiac history and was on phenytoin therapy for seizure disorder. Although bradycardia is more commonly associated with intravenous phenytoin and there were few case reports of bradycardia with oral phenytoin reported, the lit...

We have compared the incidence of bradycardia in two groups of patients undergoing cholecystectomy. Twenty consecutive patients were allocated randomly to receive either vecuronium (n = 8) or alcuronium (n = 12) as part of a standard anaesthetic technique. Bradycardia was defined as a heart rate less than 50 beat min-1. Five episodes of bradycardia occurred with vecuronium and none with alcuron...

安孫子 保 The work was supported by a grant from the Ministry of Education in Japan. In spite of numerous reports on bradycardia produced by cardiac glycosides hitherto , the mechanism is not completely clarified. Ackermann (1) reported that early digitalis bradycardia was prevented by vagal severance or by administration of atropine. This observation has generally been ac cepted. Heymans and Heyma...

AIM Asystole >3 s or sinus bradycardia with a ventricular rate <40 in association with complete heart block or sinus node dysfunction are considered to be Class 1 indications for permanent cardiac pacing. Nevertheless, these phenomena may be observed in symptomatic patients with neurocardiogenic syncope, who may not respond to pacing therapy. We hypothesized that the pattern of spontaneous brad...

Amitraz is an insecticide that frequently used as a pesticide in the world and our country. poisoning rare usually occurs pediatric age groups. Central nervous system respiratory depression, hypotension, bradycardia hyperglycemia are mainly observed poisoned patients. There no specific antidote treatment includes symptomatic measures. Herein, we report 38-year-old male patient who ingested glas...

a molecule-dependent target specifi city: mutations in parC are generally selected by pefl oxacin, ciprofl oxacin, and levofl oxacin, and those in gyrA are selected by sparfl oxacin, gatifl oxacin, moxifl oxacin, gemifl oxacin, and garenoxacin (5). In second-step mutants, mutations are present in both parC and gyrA and confer resistance to the antistreptococcal FQs levofl oxacin, moxifl oxacin,...
