What is a primary indication for performing cardioversion?

Cardioversion is a medical procedure used to restore a normal heart rhythm in cases of certain arrhythmias. A primary indication for performing cardioversion is atrial fibrillation with a rapid ventricular rate. In this condition, the atria of the heart are beating chaotically, which can lead to an uneven and potentially dangerous heart rate. When this occurs at a rapid rate, it can significantly compromise cardiac output and lead to symptoms such as palpitations, dizziness, or even hypotension.

Cardioversion effectively resets the heart's rhythm back to a normal sinus rhythm, which is crucial for maintaining sufficient blood flow throughout the body. This procedure can be mechanical (an electric shock to the heart) or pharmacological (using medication) depending on the clinical situation.

Other conditions listed may not require cardioversion. For example, bradycardia may require different interventions depending on the severity and underlying cause. Ventricular tachycardia without a pulse requires immediate defibrillation rather than cardioversion, as it is a life-threatening condition that necessitates a more aggressive approach. Stable angina is not an arrhythmia and is not an indication for cardioversion; it typically signifies coronary artery disease and is managed differently. Thus
