Ventricular pacing should be avoided when feasible in CAD to maintain output; extends mode comparisons to include oxygen consumption and efficiency.
Do different pacing modes (atrial, atrioventricular, ventricular) differentially affect myocardial oxygen consumption, blood flow, and cardiac efficiency in patients with coronary artery disease?
In patients with coronary artery disease, short-term ventricular pacing decreases cardiac output compared to atrial or atrioventricular pacing, despite having similar effects on myocardial oxygen consumption and cardiac efficiency.
Kyriakides et al. (1994) studied this question.
