Direct Current (Dc) Cardioversion / Defibrillation

A transthoracic electrical direct current (DC) shock of sufficient magnitude to depolarize the entire myocardium and sets the entire cardiac cells in the short term in the refractory period, to repeat the depolarization. After that, the fastest intrinsic pacemaker, usually the sinusatriale node wins back control of the heart rhythm. Therefore, the DC cardioversion / -Defibrillation very effectively ended tachyarrhythmias resulting from a re-entry mechanism. However, it is less effective…
