Upgrade to cardiac resynchronization therapy is an established method to treat patients with a permanent pacemaker or implantable cardioverter-defibrillator who develop symptoms of heart failure and left ventricular dysfunction. Pacing induced cardiomyopathy represents a potentially reversible cause of left ventricular dysfunction that can fully recover after implantation of biventricular pacing or conduction system pacing.
