Is right ventricular outflow tract pacing superior to right ventricular apex pacing? A long-term follow-up study
Background: We report the long-term results of our follow-up study, which compared right ventricular outflow tract (RVOT) pacing and right ventricular apex (RVA) pacing in terms of left and right ventricular function, synchrony, cardiac remodeling, the degree of valve regurgitation and clinical outcomes. Methods: Ninety-six patients with completed or high-degree atrio-ventricular block were pro...
متن کاملComparison of the haemodynamic effects of right ventricular outflow-tract pacing with right ventricular apex pacing: a quantitative review.
The right ventricular apex has been used for cardiac stimulation because this position is easily accessible and is associated with a stable position of the electrode with a low dislodgement rate. This position, however, is associated with a dyssynchronous left ventricular contraction with subsequent deleterious haemodynamic effects. Alternative stimulation sites have been studied extensively be...
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 کاملRight ventricular apex versus right ventricular outflow tract pacing: prospective, randomised, long-term clinical and echocardiographic evaluation.
INTRODUCTION In patients treated with permanent pacing, the electrode is typically placed in the right ventricular apex (RVA). Published data indicate that such electrode placement leads to an unfavourable ventricular depolarization pattern, while right ventricular outflow tract (RVOT) pacing seems to be more physiological. AIM To compare long-term effects of RVOT versus RVA pacing on clinica...
متن کاملRadiological and electrocardiographic characterization of right ventricular outflow tract pacing.
AIMS The right ventricular outflow tract (RVOT) is used as an alternative pacing site, but its superiority to the RV apex remains to be established. This lack of proof may in part be explained by heterogeneity within the RVOT-paced group, due to poor definitions of the RVOT. The aim of the present study is to characterize the RVOT in terms of fluoroscopic and electrocardiographic parameters. ...
