COMPARE-Adapta Study

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


The COMPARE-Adapta study is a randomized, multi-center, prospective study conducted in China. The purpose of the study is to compare the ability of Search AV™+ and Managed Ventricular Pacing® (MVP®) to reduce ventricular pacing in dual chamber pacemaker-indicated patients. The COMPARE-Adapta study will also observe atrial fibrillation (AF) burden as demonstrated by Cardiac Compass® and the clinical profile Adapta® pacemaker patients.


Recent studies suggest that chronic right ventricular pacing is associated with a variety of adverse effects in patients, particularly those with intact or intermittent atrioventricular (AV) conduction.

Medtronic Adapta® pacemakers include Managed Ventricular Pacing®, a pacing mode designed to promote intrinsic conduction, and also Search AV™+, a feature designed to reduce unnecessary ventricular pacing in patients with intact or intermittent AV conduction.

Medical and Biotech [MESH] Definitions

Regulation of the rate of contraction of the heart muscles by an artificial pacemaker.

A device designed to stimulate, by electric impulses, contraction of the heart muscles. It may be temporary (external) or permanent (internal or internal-external).

A cardiac arrhythmia that is caused by interaction of two independently initiated cardiac impulses of different rates from two separate foci. Generally one focus is the SINOATRIAL NODE, the normal pacemaker. The ectopic focus is usually in the HEART VENTRICLE but can be in the HEART ATRIUM or the ATRIOVENTRICULAR NODE. Modulation of the parasystolic rhythm by the sinus rhythm depends on the completeness of entrance block surrounding the parasystolic focus.

A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals may or may not conduct to the HEART VENTRICLES. Atrial premature complexes are characterized by premature P waves on ECG which are different in configuration from the P waves generated by the normal pacemaker complex in the SINOATRIAL NODE.

The artificial substitution of heart and lung action as indicated for HEART ARREST resulting from electric shock, DROWNING, respiratory arrest, or other causes. The two major components of cardiopulmonary resuscitation are artificial ventilation (RESPIRATION, ARTIFICIAL) and closed-chest CARDIAC MASSAGE.
