Brief Summary: The LEVEL-AT Trial (LEft VEntricuLar Activation Time Shortening with Physiological Pacing vs Biventricular Resynchronization therapy: a randomized study) is a non-inferiority study that aims to determine if physiological pacing could decrease the left ventricular activation time compared with biventricular therapy.
Detailed Description: To date studies have showed that physiological pacing could get similar clinical and echocardiographic response to that obtained with biventricular therapy. Activation time shortening with permanent physiological pacing has not been studied. This study will randomize 70 patients to a strategy of: biventricular pacing versus physiological pacing. LEVEL-AT study will analyze the following parameters in the 2 groups: shortening of the QRS, activation time with electrocardiographic imaging, echocardiographic asynchrony and ventricular function and clinical parameters (NYHA functional class, mortality and heart failure hospitalization). Clinical, electrocardiographic, echocardiographic and electrocardiographic imaging follow-up will be performed for 1 year.
