Final Answer:
In patients with recurrent ventricular tachycardia (VT) despite beta-blocker therapy, antiarrhythmic therapy, or catheter ablation, consideration should be given to an implantable cardioverter-defibrillator (ICD).
Step-by-step explanation:
Recurrent ventricular tachycardia is a serious cardiac arrhythmia that may pose a risk of sudden cardiac death. Beta-blockers, antiarrhythmic medications, and catheter ablation are common therapeutic approaches. However, when these treatments are ineffective or contraindicated, an ICD is often recommended.
An ICD is a device implanted under the skin that continuously monitors the heart's rhythm. If a life-threatening arrhythmia, such as VT, is detected, the ICD delivers an electric shock to restore a normal rhythm. This intervention can be life-saving in preventing sudden cardiac death in patients with recurrent VT.
