Which of the following is a treatment approach for ventricular tachycardia?

Defibrillation or cardioversion is a critical treatment approach for managing ventricular tachycardia (VT). Ventricular tachycardia is a potentially life-threatening arrhythmia characterized by rapid contractions of the ventricles, which can lead to reduced cardiac output and may progress to more serious conditions like ventricular fibrillation.

Defibrillation is typically used in cases of sustained or symptomatic VT, especially if the patient is hemodynamically unstable. It delivers an electric shock to the heart to restore a normal rhythm. Alternatively, synchronized cardioversion can be employed for patients who are stable but still exhibit persistent VT; this method also utilizes electrical shocks but is timed to coincide with the R wave of a heartbeat to minimize the risk of inducing ventricular fibrillation.

The other choices do not address the direct and urgent intervention needed for ventricular tachycardia. Thrombolytics are used for dissolving blood clots, which is not relevant in the context of treating arrhythmias. Deep breathing exercises are more suited for managing anxiety or mild respiratory issues rather than acute cardiac conditions. Increased dietary sodium does not influence the treatment of ventricular tachycardia and may actually exacerbate some cardiovascular conditions. Thus, defibrillation or cardioversion remains
