Key result
Right ventricular outflow tract pacing yielded a higher cardiac index than apex pacing at 85 beats/min (2.42 vs 2.04 L/min/m2, P<0.002), 100 beats/min, and 120 beats/min.

May favor RVOT over apex pacing for acute hemodynamics; leaves open long-term outcome data from randomized studies.
Does right ventricular outflow tract pacing improve cardiac index compared to right ventricular apex pacing in patients undergoing cardiac catheterization?
Absolute Event Rate: 2.42% vs 2.04%
p-value: p=<0.002
Right ventricular outflow tract pacing provides significant acute hemodynamic benefits over conventional apex pacing, particularly in patients without significant coronary artery disease or left ventricular dysfunction.
Cock et al. (1998) studied Patients undergoing cardiac catheterization (n=17). Right ventricular outflow tract pacing vs. Right ventricular apex pacing was evaluated on Cardiac index at 85 beats/min (p=<0.002). Right ventricular outflow tract pacing yielded a higher cardiac index than apex pacing at 85 beats/min (2.42 vs 2.04 L/min/m2, P<0.002), 100 beats/min, and 120 beats/min.
