Electrical shock in cardiology are pursuid transfer of electrons to the myocardium. Its main indications are`s cardioversion and defibrillation. The electrical shock therapy follows laws of electricity laws and consequently, its main difficulty is the impedance or resistance of electrons flow. To make better the effectiveness of this therapy, a number of improvements have been made on the shock wave, its duration, and polarity. The electric shock therapy has become the preferred treatment when dealing with cardiorespiratory arrest secondary, ventricular fibrillation and pulseless ventricular tachycardia. Similarly, it is the preferred treatment for ventricular tachyarrhythmia associated with hemodynamic compromise. Despite its significant advantages, this treatment causes secondary effects, which should adequately be known in order to provide a timely treatment.
