Cardiac Pacemaker and Defibrillator

With the understanding of cardiovascular diseases and development of technology, the original concept of pacing as a treatment for heart block has expanded dramatically. A large number of well-designed, randomized clinical trials have supported the applications of novel implantable devices, which revealed a booming era in the therapy of bradyarrhythmias, tachyarrhythmias, as well as heart failure. In this chapter, we will give a general overview of the principle and advances of cardiac pacemaker and defibrillator.
