Cardioversion

Description

• Cardioversion is synchronized countershock to convert an undesirable rhythm to a stable rhythm.
• Cardioversion can be an elective procedure performed by the HCP for stable tachydysrhythmias resistant to medical therapies or an emergent procedure for hemodynamically unstable ventricular or
• supraventricular tachydysrhythmias.
• A lower amount of energy is used than with defibrillation.

• The defibrillator is synchronized to the client’s R wave to avoid discharging the shock during the vulnerable period (T wave).
• If the defibrillator is not synchronized, it could discharge on the T wave and cause VF.
