INTRINSIC RV - Inhibition of Unnecessary RV Pacing With AV Search Hysteresis in ICDs

2010-07-15 17:00:00 | BioPortfolio


INTRINSIC RV is a two-armed randomized trial that will compare the effects of innovative dual-chamber pacing with AV Search Hysteresis to standard VVI among ICD patients.


The purpose of study is to assess whether AVSH will provide benefits of a dual-chamber ICD without the deleterious effects of unnecessary RV pacing. This study will aim to demonstrate that DDDR-AVSH is equal to VVI with respect to mortality and HF hospitalizations.

Reasons for and predictors of acute hospitalization versus elective outpatient implantable cardioverter-defibrillator implantation and subsequent differential clinical outcomes.

Medical and Biotech [MESH] Definitions

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.

Types of artificial pacemakers with implantable leads to be placed at multiple intracardial sites. They are used to treat various cardiac conduction disturbances which interfere with the timing of contraction of the ventricles. They may or may not include defibrillating electrodes (IMPLANTABLE DEFIBRILLATORS) as well.

A generic expression for any tachycardia that originates above the BUNDLE OF HIS.

Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.

A rare form of supraventricular tachycardia caused by automatic, not reentrant, conduction initiated from sites at the atrioventricular junction, but not the ATRIOVENTRICULAR NODE. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication with a HEART RATE ranging from 140 to 250 beats per minute.
