What is the primary goal of "synchronized cardioversion"?

The primary goal of synchronized cardioversion is to correct atrial fibrillation or atrial flutter with a rapid ventricular response. This procedure is specifically designed to restore a normal sinus rhythm in patients who are experiencing these types of arrhythmias. During atrial fibrillation or flutter, the heart's electrical signals fire chaotically, leading to an ineffective pumping action. This can result in rapid heart rates and decreased cardiac output, which can be symptomatic and potentially harmful to the patient.

Synchronized cardioversion delivers a controlled electrical shock to the heart during a specific phase of the heart's electrical cycle, specifically during the R wave of the QRS complex, to minimize risks of inducing a more dangerous arrhythmia. The goal is to "reset" the heart to its normal rhythm, improving hemodynamics and alleviating symptoms associated with the rapid ventricular response.

While normalizing heart rate, avoiding myocardial infarction, and inducing bradycardia may be clinical concerns in managing arrhythmias, these are not the primary objectives of synchronized cardioversion. The main indication for this procedure remains the correction of atrial fibrillation or flutter, making this choice the most appropriate answer.
