Calcium handling in zebrafish ventricular myocytes.
The zebrafish is an important model for the study of vertebrate cardiac development with a rich array of genetic mutations and biological reagents for functional interrogation. The similarity of the zebrafish (Danio rerio) cardiac action potential with that of humans further enhances the relevance of this model. In spite of this, little is known about excitation-contraction coupling in the zebr...
متن کاملPathogenesis of Ventricular Tachyarrhythmias
• Volume 120 • Number 4 www.anesthesia-analgesia.org 737 Copyright © 2015 International Anesthesia Research Society DOI: 10.1213/ANE.0000000000000556 During the past few decades, cardiac electrophysiology (EP) has evolved from a specialty that primarily implanted simple pulse generators (pacemakers) for bradycardia therapy to a specialty with an expanded practice in detecting and terminating ar...
متن کاملIdiopathic Ventricular Tachyarrhythmias
Background Torsade de pointes is characterized not only by its particular ECG pattern but by its context of congenital or acquired long QT syndrome and the long coupling interval of the initial premature beat. Methods and Results We observed 14 patients aged 34.6±10 years (mean±SD) with no structural heart disease who presented with syncope related to a typical ECG aspect of torsade de pointes....
متن کاملDo atrial tachyarrhythmias beget ventricular tachyarrhythmias in defibrillator recipients?
OBJECTIVES This study was designed to analyze the incidence of "dual tachycardia"-ventricular tachycardia (VT) or ventricular fibrillation (VF) preceded by paroxysmal atrial tachycardia (AT) or atrial fibrillation (AF)-in patients receiving dual-chamber implantable cardioverter defibrillators (ICDs). BACKGROUND Paroxysmal AT/AF occurs commonly in patients who receive ICDs for the treatment of...
متن کاملDifferentiation of ventricular tachyarrhythmias.
Implantable devices capable of several modes of therapy will require differentiation of various ventricular tachyarrhythmias. Three methods of arrhythmia analysis, magnitude-squared coherence, ventricular rate, and irregularity of cycle length were performed for 45 episodes of induced ventricular tachyarrhythmia in 15 patients. Differentiation of monomorphic ventricular tachycardia from polymor...
