The left ventricle strives valiantly with each cardiac cycleto maximize contractility and provide protection against lethalventricular arrhythmias. Heart failure can make this coordinationdifficult. Heart-rhythm and heart-failure specialists are increasinglyworking together to restore nature's performance and lifesavingfeatures to the failing left ventricle. Our jobs are becomingprogressively more entwined as we evaluate treatments involvingpacemakers and implantable cardioverterdefibrillators(ICDs) in an effort to improve the quality of life and reducethe risk of complications and death among patients with leftventricular systolic dysfunction.
Several factors contribute to this new collaboration. First,heart-rhythm specialists acknowledge the dramatic . . . [Full Text of this Article]
