The treatment of congestive heart failure by implanted biventricular pacemakers, or cardiac resynchronization, has revolutionized the practice of implanting pacemakers and defibrillators. More cardiac resynchronization therapy devices than conventional pacemakers are now being implanted and their numbers are growing worldwide. This comprehensive volume will be useful to cardiologists, cardiac electrophysiologists, cardiac surgeons, cardiology fellows in training, intensive care specialists and anyone interested in pacing, ICDs and their follow-up. It will comprise 504 pages in total with 260 figures and electrocardiograms, with 110 color illustrations.
