Question: 1 / 400

What should the defibrillator be set to when performing cardioversion on narrow and regular rhythms?

50-100 Joules

When performing cardioversion on narrow and regular rhythms, the defibrillator should be set between 50 to 100 Joules. This range is effective and safe for the delivery of synchronized shocks in instances such as supraventricular tachycardia (SVT) or atrial flutter, where the rhythm is rapid but the QRS complexes are narrow and uniform.

Setting the energy level between 50 and 100 Joules helps to minimize the risk of causing damage to the heart tissue while maximally increasing the likelihood of returning to a normal sinus rhythm. Higher energy settings are typically reserved for wider QRS complexes or unstable rhythms, as these require more energy to achieve successful defibrillation. This distinction is crucial in emergency care, as appropriate energy levels are essential for successful cardioversion while also ensuring patient safety.
