The right ventricular outflow tract: the road to septal pacing.
نویسندگان
چکیده
BACKGROUND Pacing from the right ventricular apex is associated with long-term adverse effects on left ventricular function. This has fuelled interest in alternative pacing sites, especially the septal aspect of the right ventricular outflow tract (RVOT). However, it is a common perception that septal RVOT pacing is difficult to achieve. METHODS AND RESULTS In this article, we will review the anatomy of the RVOT and discuss the importance of standard radiographic views and the 12-lead electrocardiogram in aiding lead placement. We will also describe a method utilizing a novel stylet shape, whereby a conventional active-fixation, stylet-driven lead can be easily and reliably deployed onto the RVOT septum.

Right 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 کاملReal-time three-dimensional echocardiographic determination of right ventricular outflow tract high septal pacing sites.
OBJECTIVE To investigate the feasibility of determination of right ventricular outflow tract (RVOT) high septal pacing site visualized by real-time three-dimensional echocardiography (RT3DE). METHODS The forty subjects with RVOT pacing were analysed. RT3DE determination of RVOT high septal pacing sites was compared with chest X-ray (CXR). RESULTS RVOT septal pacing sites could be obtained i...
متن کاملSeptal Pacing of Right Ventricle: Has The Last Word Been Said?
The deleterious effects of Right ventricular (RV) pacing on development of ventricular dyssynchrony leading to heart failure, genesis of atrial fibrillation and consequent increased mortality have been repeatedly demonstrated in numerous pacing studies. Trials with dual chamber pacemakers and defibrillators did not succeed in negating these effects, raising the question if it was RV pacing per ...
متن کاملMeasurements of conduction times with catheter electrodes during pacing from different ventricular sites.
Filtered bipolar catheter electodes, I mm apart, were used to pace and record from the high right atrium, right ventricular apex, right ventricular outflow tract, right ventricular inflow tract, middle cardiac vein, great cardiac vein, and endocardium of the left ventricular septal surface. Right ventricular apex to middle cardiac vein and the middle cardiac vein to right ventricular apex condu...
متن کاملRight ventricular pacing for right ventricular outflow tract obstruction in a man with biventricular hypertrophic cardiomyopathy.
A 40-year-old man with known hypertrophic cardiomyopathy presented with syncope after coughing. Physical examination revealed a systolic murmur that was accentuated by the Valsalva maneuver. An electrocardiogram suggested biventricular hypertrophy and biatrial enlargement (Fig. 1). Echocardiograms revealed asymmetric septal hypertrophy with a diastolic septal thickness of 2.3 cm, and evidence o...
