Effects of Right Ventricular Pacemaker Lead Position Assessed by MRI

Austria24 participantsStarted 2012-09

Plain-language summary

Chronic right ventricular apical pacing has been associated with negative hemodynamic effects. Clinical outcome of right ventricular pacing can be influenced by multiple factors. An important factor seems to be optimal lead positioning. Data regarding left ventricular function impaired by lead positioning is insufficient. The aim of the present study therefore is to compare right ventricular apical pacing (RVAP) with right ventricular septal pacing (RVSP). Outcome measurements are echocardiographic features, magnetic resonance imaging and clinical outcome.
