How do you treat a fast, wide-QRS rhythm when the patient's blood pressure is 120 over 85? Start with vital signs: assess stability. The pressure is normal, and no instability is reported. The regular pattern is monomorphic VT, a wide-QRS tachycardia. That is the turn: this patient is stable, so IV amiodarone is the listed antiarrhythmic. Beta-blockers and nitroglycerin are not the best rhythm treatment here. If unstable, synchronized cardioversion comes first. With stable vital signs, give IV amiodarone.
