Background— The INTRINSIC R (Inhibition of Unnecessary R Pacing with ASH in ICDs) study tested the hypothesis that dual-chamber rate-responsie with atrioentricular search hysteresis 60-130 programming is not inferior to single-chamber–40 programming in an implantable cardioerter defibrillator with respect to all-cause mortality and heart failure hospitalizations using an equialence margin of 5%.
