High Power Circuitry, the much higher voltage (usually up to 750 V) necessary for successful defibrillation. Secondly, after this high voltage energy is concentrated in the capacitor, output switching circuitry then transfers this energy to the heart.

The Electrophysiological Effects of Defibrillation Shocks,attaining such an understanding. This chapter will discuss what has been thought and what we have learned about the electro-physiological effects of shocks and how these effects relate to the overall defibrillation process.

Anti-Tachycardia Pacing and Cardioversion,ith fibrillation as the only documented or induced arrhythmia, many of these same patients had their VF episodes initiated by VT or have subsequent tachycardia episodes. About a third of the patients with ICDs implanted for cardiac arrest develop spontaneous monomorphic VTs and the vast majority are pace terminable..
