Ventricular remodeling in right ventricular apical pacing.
OBJECTIVE To determine ventricular remodeling (VR) and the role of clinical and functional variables in patients with normal cardiac function who underwent right ventricular apical pacing (RVAP). METHODS Among the 268 consecutive patients with standard pacemaker due to complete atrioventricular block (CAVB), those with left ventricular ejection fraction (LVEF) < 55% and left ventricular end-d...
متن کاملThe Downside of Right Ventricular Apical Pacing
The right ventricular (RV) apex has been the standard pacing site since the development of implantable pacemaker technology. Although RV pacing was initially only utilized for the treatment of severe bradyarrhythmias usually due to complete heart block, today the indications for and implantation of RV pacing devices is dramatically larger. Recently, the adverse effects of chronic RV apical paci...
متن کاملRight Ventricular Outflow Tract Septal Pacing Is Superior to Right Ventricular Apical Pacing
BACKGROUND The effects of right ventricular apical pacing (RVAP) and right ventricular outflow tract (RVOT) septal pacing on atrial and ventricular electrophysiology have not been thoroughly compared. METHODS AND RESULTS To identify a more favorable pacing strategy with fewer adverse effects, 80 patients who had complete atrioventricular block with normal cardiac function and who were treated...
متن کاملElectrocardiographic identification of prior myocardial infarction during right ventricular pacing--effect of septal versus apical pacing.
BACKGROUND Electrocardiographic (ECG) identification of prior myocardial infarction (MI) during right ventricular (RV) pacing is of clinical importance. Proposed ECG criteria have been evaluated only during apical pacing. We evaluated the effect of pacing site on the predictive performance of ECG signs of prior MI. METHODS The present study is a secondary analysis of a prospective, multicente...
متن کاملImproved left ventricular relaxation during short-term right ventricular outflow tract compared to apical pacing.
STUDY OBJECTIVES Pacing-induced asynchrony may deteriorate left ventricular function; however, limited data exists in humans. The aim of our study was to compare left ventricular hemodynamics during short-term atrioventricular sequential pacing from the right ventricular apex and from the outflow tract of the right ventricle. DESIGN Three 5-min pacing intervals were applied in a random order,...
