Primary Outcome Measures:
- Change from Baseline in Left ventricular mass and resting left ventricular outflow tract gradient (mmHg). [ Time Frame: 1 and 2 years ] [ Designated as safety issue: No ]Change from Baseline in Left ventricular mass and resting left ventricular outflow tract gradient (mmHg)
Secondary Outcome Measures:
- Change from Baseline in Clinical evaluation of NYHA,QoL,6MWT,interventricular septum thickness,posterior wall thickness,provoked left ventricular outflow tract gradient,mitral regurgitation grade. [ Time Frame: 1 and 2 years ] [ Designated as safety issue: No ]Change from Baseline in Clinical evaluation (New York Heart Association(NYHA), Quality of life Questionnaire (QoL), 6 Minutes Walk Test (6MWT)), interventricular septum thickness, posterior wall thickness, provoked left ventricular outflow tract gradient, mitral regurgitation grade.

Detailed Description:
In this study, subjects will be randomized to Cardiac Resynchronization Therapy-Defibrillation (CRT-D) or Cardiac Resynchronization Therapy-Pacing (CRT-P) vs Pacing Therapy AAI. Randomization will be stratified by indication. Optimal pharmacological therapy in both treatment arms. Length of follow-up for each subject will be 2y, since all subjects will be followed to a common study termination date.
