Quizplus · Accepted Answer

Both 1 and 2 are correct statements about the differences between cardioversion and defibrillation. In cardioversion, the countershock is synchronized with the R wave in order to prevent the shock from being delivered during the vulnerable period of the cardiac cycle, which could lead to a more dangerous arrhythmia. Additionally, in defibrillation, more energy is applied because the goal is to completely depolarize the heart and stop any chaotic rhythms, while in cardioversion the goal is to restore a specific normal rhythm.
