Final answer:
For hemodynamically unstable patients with Ventricular Tachycardia and a pulse, defibrillation is the recommended urgent treatment to reestablish a normal sinus rhythm. In chronic cases of arrhythmia, implantation of an artificial pacemaker may be necessary to regulate heart function.
Step-by-step explanation:
The treatment for Ventricular Tachycardia (V-Tach) with a pulse, but who is hemodynamically unstable, typically requires immediate medical intervention. If the patient is experiencing severe symptoms due to the arrhythmia, a controlled electric shock through defibrillation can be administered. This method uses special paddles to deliver a charge to the heart in an attempt to resume a normal sinus rhythm. The procedure effectively stops the heart momentarily, which allows the sinoatrial (SA) node to restart a normal heartbeat cycle. For continuous management of arrhythmias, an artificial pacemaker may be implanted, which delivers electrical impulses to the heart muscle, ensuring effective pumping and regulation of the heart rate. In cases where the arrhythmia is life-threatening, as in Ventricular Fibrillation, it is often referred to as "code blue" and necessitates life support measures.
