Key result
Septal pacing using a stylet with distal posterior angulation resulted in a narrower QRS duration compared to anterior or free wall pacing (136 vs 155 ms, P<0.001).
Why the study?
Does a stylet with distal posterior angulation improve reliable septal lead positioning and reduce QRS duration compared to standard or anterior angulation in patients undergoing RVOT pacing?
Does a stylet with distal posterior angulation improve reliable septal lead positioning and reduce QRS duration compared to standard or anterior angulation in patients undergoing RVOT pacing?
Absolute Event Rate: 136% vs 155%
p-value: p=<0.001
Using a stylet with distal posterior angulation reliably achieves septal pacing in the RVOT, which produces a narrower QRS duration than anterior or free wall pacing.

May support posterior stylet angulation for narrower QRS in RVOT pacing; leaves open clinical outcome impact pending RCTs.
Hillock et al. (2007) studied Patients requiring right ventricular outflow tract (RVOT) pacemaker lead placement. Septal pacing (using stylet with distal posterior angulation) vs. Anterior or free wall pacing was evaluated on QRS duration (p=<0.001). Septal pacing using a stylet with distal posterior angulation resulted in a narrower QRS duration compared to anterior or free wall pacing (136 vs 155 ms, P<0.001).
