Which of the following is used to prevent recurrence of this rhythm disorder?
Catheter ablation
Adenosine
Synchronized Defibrillation with 120 Joules biphasic
Non synchronised DC Shock 200 Joules biphasic
ECG shows hea rate of 200/min with narrow complex tachycardia. There is global segment depression and hidden P waves which is a feature of Paroxysmal Supraventricular tachycardia. Choice A is the answer as Catheter ablation will be used to prevent recurrence of such episodes. For example, in AVN, the slow pathway is ablated, which prevents the reentry cycle Choice B is used for chemical cardioversion in case of PSVT Choice C is used for electrical cardioversion in case of PSVT Choice D is used for Ventricular fibrillation and pulseless VT.
