Primary Outcome Measures

Name	Time	Method
To evaluate if RVHS pacing results in significantly improved left ventricular function (as measured by left ventricular ejection fraction) when compared to RVA pacing.[Measured after 24 months of pacing.]

Secondary Outcome Measures

Name	Time	Method
To evaluate if RVA pacing causes greater degree of left ventricular mechanical dyssynchrony compard to RVHS pacing.[At end of 24 month period.]
