C) Verapamil Wide-complex tachycardia = assume VT until proven otherwise. Do NOT give verapamil unless you are confident the rhythm is a specific supraventricular tachycardia that is verapamil-sensitive.

✓ C) Verapamil. Verapamil is contraindicated in ventricular tachycardia because its negative inotropic and vasodilatory effects cause severe hypotension and potential hemodynamic collapse. Conversely, amiodarone, lidocaine, and procainamide are indicated antiarrhythmics routinely used for wide-complex ventricular rhythm management.

That is a very interesting question. The ECG shows polymorphic ventricular tachycardia, for which first line management is intravenous magnesium infusion. Another option is isoprenaline, which is contraindicated in usual VT. There are fascicular VTs which are verapamil responsive

The correct answer is C) Verapamil. Key Explanations Verapamil (Class IV Antiarrhythmic / Calcium Channel Blocker): Contraindicated in Ventricular Tachycardia (VT): Verapamil causes peripheral vasodilation and negative inotropism. Administering it to a patient in VT can precipitate severe hypotension, cardiovascular collapse, peripheral vascular collapse, and degeneration into Ventricular Fibrillation (VF) or cardiac arrest. Rule of Thumb: Never give Verapamil for wide-complex tachycardia unless it is conclusively proven to be SVT with aberrancy (or specific Belhassen / fascicular VT under expert guidance). Why the Other Options Are Used A) Amiodarone (Class III): First-line intravenous antiarrhythmic choice for stable monomorphic VT and pulseless VT/VF refractory to defibrillation. B) Lidocaine (Class IB): Commonly used as an alternative or adjunct for VT, especially in the context of acute myocardial ischemia or infarction. C) Procainamide (Class IA): Highly effective first-line drug for hemodynamically stable monomorphic VT (as recommended by ACLS guidelines).

C.Verapamil Verapamil should NOT be used in ventricular tachycardia (VT). Amiodarone - used for VT. Lidocaine - can be used for VT. Procainamide - can be used for stable monomorphic VT. Verapamil - AV-nodal blocker, may cause hemodynamic deterioration in VT.

Calcium channel blockers C

The correct answer is C) Verapamil. Explanation Verapamil (a non-dihydropyridine calcium channel blocker) is contraindicated in the management of wide-complex ventricular tachycardia (VT). Mechanism of Toxicity: Verapamil causes peripheral vasodilation and negative inotropy without suppressing ventricular arrhythmias. Administration during VT often precipitates severe hypotension, cardiovascular collapse, VF (ventricular fibrillation), or cardiac arrest. Clinical Pitfalls: A common board exam trap is mistaking VT for SVT with aberrancy. Giving Verapamil to a hemodynamically stable patient with a wide-complex tachycardia under the mistaken assumption that it is SVT can be fatal.

Está claro que es el verapamilo, pero lo que debe hacerse es cardiovertir tras sedar al paciente en profundidad y NO PERDER EL TIEMPO HACIENDO UN EKG DE 12 DERIVACIONES…!!!!!!!!!

This is a so-called short-long-short sequence, the question is referring to Torsade, and the answer is Amiodarone which would further prolong the QT. However, this question is problematic because the "short" in TdP is typically not really short, and most commonly >500ms.

Looks like a Torsades for me. I would not use amiodarone

Great case highlighting the importance of distinguishing VT from SVT with aberrancy. Wide-complex tachycardias require a systematic approach before choosing therapy.
