Myocardial contractile reserve predicts improvement in left ventricular function after cardiac resynchronization therapy.

abstract：BACKGROUND:Patients with an implantable cardioverter defibrillator (ICD) are at increased risk of anxiety disorders. In turn, anxiety has been identified as a precipitant of ventricular arrhythmias. Anxiety may in part be attributed to concerns about the ICD firing, but the relationship between ICD concerns, psychologi...
