Response by Friedman and Al-Khatib to Letter Regarding Article, "Ventricular Fibrillation Conversion Testing After Implantation of a Subcutaneous Implantable Cardioverter Defibrillator: Report From the National Cardiovascular Data Registry".
Catheter ablation for polymorphic ventricular tachycardia and ventricular fibrillation (PMVT/VF) may target triggering premature ventricular contractions (PVCs). Targeting ventricular scar has also be...
This is a prospective, open label, single-center study, in kidney transplant recipients with stable renal function for 12 and 120 months after transplantation, that are in use use of calci...
The ASSURE Study will evaluate shock conversion performance when programming the first shock of an implantable cardioverter-defibrillation (ICD) is based on an implant test consisting of e...
Double blind study to assess versus placebo the efficacy of SSR149744C for the conversion of atrial fibrillation/flutter to sinus rhythm at the time of the planned electrical cardioversion...
The aim of this study is to test the impact of the managed ventricular pacing (MVP) mode and atrial preventive and antitachycardia pacing therapies on the reduction of a composite clinical...
This study is being conducted to demonstrate the effectiveness of RSD1235 in the conversion of atrial fibrillation to sinus rhythm.
A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.
A potentially lethal cardiac arrhythmia characterized by an extremely rapid, hemodynamically unstable ventricular tachycardia (150-300 beats/min) with a large oscillating sine-wave appearance. If untreated, ventricular flutter typically progresses to VENTRICULAR FIBRILLATION.
Work consisting of a critical or explanatory note written to discuss, support, or dispute an article or other presentation previously published. It may take the form of an article, letter, editorial, etc. It appears in publications under a variety of names: comment, commentary, editorial comment, viewpoint, etc.
Implantable devices which continuously monitor the electrical activity of the heart and automatically detect and terminate ventricular tachycardia (TACHYCARDIA, VENTRICULAR) and VENTRICULAR FIBRILLATION. They consist of an impulse generator, batteries, and electrodes.
A malignant form of polymorphic ventricular tachycardia that is characterized by HEART RATE between 200 and 250 beats per minute, and QRS complexes with changing amplitude and twisting of the points. The term also describes the syndrome of tachycardia with prolonged ventricular repolarization, long QT intervals exceeding 500 milliseconds or BRADYCARDIA. Torsades de pointes may be self-limited or may progress to VENTRICULAR FIBRILLATION.
