Abstract |
Cardiac resynchronization therapy by a biventricular pacemaker or defibrillator is recommended for treating selected patients with systolic heart failure who are in NYHA class III or IV despite optimal medical therapy, have a left ventricular ejection fraction of < or = 35%, and a QRS width of > or = 120 ms. Improvement in symptoms or ventricular remodelling is observed in 50-80% of patients. In order to improve response to treatment, several strategies are proposed, including patient selection, lead positioning and device optimization.
