The aim of this study is to assess the benefits from the AAISafeR/SafeR algorithm of Symphony 2550 or REPLY DR in a wide range of pacemaker patients.
The expected benefits will be a result of the reduction of the percentage of ventricular pacing.
It contributes to the longevity of the cardiac pacemaker and has an effect on the incidence of sustained (or persistent) Atrial Fibrillation and Heart Failure. These clinical benefits are a result of spontaneous ventricular activation which ensures a more physiological ventricular activation.
The benefits will be assessed by comparing the incidence of atrial arrhythmias and the evolution of the haemodynamic status of the patients (QOL, echo and BNP)

This is a reply to the commentary of Ossorio and Zhou.
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.
Visualization of the heart structure and cardiac blood flow for diagnostic evaluation or to guide cardiac procedures via techniques including ENDOSCOPY (cardiac endoscopy, sometimes refered to as cardioscopy), RADIONUCLIDE IMAGING; MAGNETIC RESONANCE IMAGING; TOMOGRAPHY; or ULTRASONOGRAPHY.
Striated muscle cells found in the heart. They are derived from cardiac myoblasts (MYOBLASTS, CARDIAC).
Precursor cells destined to differentiate into cardiac myocytes (MYOCYTES, CARDIAC).
A group of cardiac arrhythmias in which the cardiac contractions are not initiated at the SINOATRIAL NODE. They include both atrial and ventricular premature beats, and are also known as extra or ectopic heartbeats. Their frequency is increased in heart diseases.
