Comparison of right ventricular outflow tract and apical lead permanent pacing on cardiac output

Am J Cardiol. 1997 Jan 15;79(2):209-12. doi: 10.1016/s0002-9149(96)00718-7.

Abstract

Cardiac output was measured in 89 patients using transthoracic continuous-wave echo Doppler comparing right ventricular outflow tract pacing with the right ventricular apex at the time of permanent pacemaker implantation. Overall, cardiac output improved 18.8% (p <0.0001) and cardiac index 21.0% (p <0.0001) with outflow tract placement; patients with a lower baseline cardiac index had a greater percent improvement with outflow tract placement.
