Randomized Controlled Trial Multicenter StudyReduced risk of life-threatening ventricular tachyarrhythmias with cardiac resynchronization therapy: relationship to left ventricular ejection fraction.
We hypothesized that the relationship between LVEF and the risk of life-threatening ventricular tachyarrhythmias (VTAs) may modify the effect of a CRT device with a defibrillator (CRT-D) on VTA risk. ⋯ Our data suggest that in mild HF patients with cardiomyopathy there is an inverse correlation between LVEF and the risk of life-threatening VTAs, possibly contributing to the attenuation in the antiarrhythmic properties of CRT with increasing left ventricular function.
