Atrial conduction disorders are frequent in elderly subjects and/or those with structural heart
diseases, mainly mitral valve disease, hyperthrophic cardiomyopathies, and hypertension …

DDD pacemakers sense and pace right‐sided cardiac chambers. The relationship of atrial to
ventricular systole on the left side of the heart is of importance for systemic hemodynamics …

The current method of pacing the right atrium from the appendage or free wall is often the
source of delayed intraatrial conduction and discoordinate left and right atrial mechanical …

Biatrial Pacing for Atrial Tachyarrhythmia Prevention. Introduction. Results of previous
studies suggest that atrial resynchronization by multisite atrial pacing may coutribute to …

The role of permanent pacing in preventing atrial fibrillation in patients at risk for this
arrhythmia is a relatively new concept. Existing retrospective studies support the superiority …

Right atrial septal pacing yields shorter interatrial conduction delays than conventional right
atrial pacing at the free wall or the right atrial appendage. However, the hemodynamic …

Background: Enhanced AAI/R pacing minimizes right ventricular pacing but may permit or
induce AV decoupling (AV‐DC) due to unrestricted AV intervals (AVIs). The purpose of this …

Background Multiple-site atrial pacing has been shown to prevent recurrence of atrial
fibrillation. However, information about the mechanisms of different atrial pacing modes in …

There is increasing evidence that single site atrial pacing is beneficial for atrial fibrillation
(AF) prevention in sick sinus syndrome. Multisite atrial pacing methods such as dual site …

Background Atrial dysrhythmia patients have exaggerated intra-atrial conduction delays and
prolonged relative refractoriness in response to atrial premature depolarizations (APDs) …
