LVEF at the time of ICD generator replacement is, on average, 4% to 5% higher than at the time of initial implant,6 and patients may have improvement in their LVEF to >35%, the cutoff used to risk stratify the majority of patients at time of initial implant.
Can a pacemaker defibrillator improve ejection fraction?
Biventricular pacemaker is a special pacemaker, which is used to synchronize the contractions of the left ventricle with the right ventricle, to improve the ejection fraction in patients with severe and moderately severe symptoms of heart failure.
Does cardiac resynchronization therapy improve ejection fraction?
Cardiac resynchronization therapy improves ejection fraction and cardiac remodelling regardless of patients' age. Europace.
