Supraventricular Arrhythmias and Treatment
The objective of this article is to review supraventricular arrhythmias emphasized the importance of atrial fibrillation (AF) and its novel therapeutic approach in dogs. Supraventricular arrhythmias include disturbances of impulse formation at sinus node, atria and junctional area or alterations of impulse conduction within the chamber above ventricles. Among those supraventricular arrhythmias,...
متن کاملGlucocorticoid Regulation of Cardiac K Currents and L-Type Ca Current in Neonatal Mice
Previous studies have reported that dexamethasone (Dex) prolongs cardiac action potential repolarization in mice and rats. However, the cellular mechanisms of this effect have not been addressed. Because action potential duration is influenced by a complex interplay of both inward and outward currents, this study evaluated the role of K currents and the L-type Ca current in response to chronic ...
متن کاملLife-threatening Supraventricular Arrhythmias: Management
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...
متن کاملManagement of common arrhythmias: Part I. Supraventricular arrhythmias.
Family physicians frequently encounter patients with symptoms that could be related to cardiac arrhythmias, most commonly atrial fibrillation or supraventricular tachycardias. The initial management of atrial fibrillation includes ventricular rate control to provide adequate cardiac output. In patients with severely depressed cardiac output and recent-onset atrial fibrillation, immediate electr...
متن کاملIntravenous Amiodarone for Supraventricular Arrhythmias in Children
In this issue of the Journal, Chang et al1 present a thought-provoking, single-center retrospective analysis of 37 patients receiving either procainamide or IV amiodarone for refractory supraventricular arrhythmias (SVA), excluding junctional ectopic tachycardia (JET). They compare the relative efficacy of the drugs, finding procainamide to be fully successful in 50% of cases, whereas amiodaron...
