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 ...

This essay is designed to review some of the basic and more recent contributions to our understanding of supraventricular tachyarrhythmias, their mechanisms, pertinent points in diagnosis, and treatment. Supraventricular tachycardia is discussed under the concept of reentrant mechanisms versus accelerated ectopic pacemakers. Atrial fibrillation and flutter, multifocal atrial tachycardia, suprav...

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...

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. ...

Objective Supraventricular arrhythmias are commonly detected in patients with anti-mitochondrial antibody M2 (AMA-M2)-associated myopathy. However, the prevalence of supraventricular arrhythmias in unselected AMA-M2-positive patients and the impact of AMA-M2 on supraventricular arrhythmias have yet to be fully investigated. Methods We analyzed 384 patients (116 men; age, 60 [48-69] years), who ...

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...

The cardiac tachyarrhythmias can be divided into 2 major groups. A. Supraventricular B. Ventricular The supraventricular tachyarrhythmias, commonly seen in clinical practice are: 1. Supraventricular tachycardias. 2. Atrial flutter 3. Atrial fibrillation Supraventricular arrhythmias can be life threatening a. When associated with underlying LV dysfunction heart failure. b. In association with WP...

OBJECTIVES The purpose of this study was to examine the effects of supraventricular pacing tachycardia on left ventricular function and myocardial structure in newborn, immature pigs and to determine whether immature pigs respond to supraventricular tachycardia differently from adults. BACKGROUND Previous studies have shown that supraventricular tachycardia causes dilated cardiomyopathy in ad...
