background: this study was done to assess the efficacy and adverse effects of the different doses of adenosine in the pediatric age group with respect to multiple patient variables.   methods: over a period of 1 year, 86 occasions of supraventricular tachycardia (svt) were treated with adenosine in 81 infants and children aged between 18 days and 12 years (median of 1.3 years, sd=3). adenosine ...

background supraventricular tachycardia (svt) is the most frequent arrhythmia requiring a medical treatment in neonates. objectives the aim of our study was to evaluate and manage neonatal supraventricular tachycardia. methods this study was performed on 22 newborns that were diagnosed with svt at two neonatal intensive care units (nicu) in south west of iran from october 2012 to october 2015. ...

a 17 year old male who underwent surgery for thoracic outlet syndrome developed a postoperative complication which was labelled and diagnosed as malignant hyperthermia in kerman medical center. the temperature recorded was 43°c, pac02 70 mmhg and serum potassium level was 7 meq/l. the patient was hospitalized in the intensive care unit for 10 days. on discharge, the patient had aphasia and inco...

propafenone hci (p), is a relatively new class ic antiarrhythmic agent. it has been reported to be superior to conventional antiarrhythmics in the control of supraventricular, ventricular and wpw associated tachyarrhythmias. it has been also shown to be well tolerated. in our study protocol, which extends over 2~ years period , we used (p) in 87 patients for management of various types of cardi...

anotomical boundary of atrioventricular node reentrant tachycardia (avnrt) is composed of fast and slow pathways right atrium in upper turnaround and common distal pathway in lower turnaround. we performed electophsiologic study (eps) in 152 patients and could show the existence of distal common pathway with decremental conduction properties in approximately 40 patients.

INTRODUCTION Standard electrophysiologic techniques generally allow discrimination among mechanisms of paroxysmal supraventricular tachycardia. The purpose of this study was to determine whether the response of paroxysmal supraventricular tachycardia to atrial and ventricular overdrive pacing can help determine the tachycardia mechanism. METHODS AND RESULTS Fifty-three patients with paroxysma...

Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...

OBJECTIVE This prospective study investigated the diagnostic significance of the N-terminal pro-brain natriuretic (NT-proBNP) and troponin I peptides in emergency department patients presenting with palpitations. METHODS Two groups of patients with palpitations but without documented supraventricular tachycardia were compared: a group with supraventricular tachycardia (n = 49) and a control g...
