Using drugs appropriate for supraventricular tachycardia (eg, verapamil, diltiazem) in patients with VT may cause hemodynamic collapse and death. Patients with persistent or recurrent VT after administration of antiarrhythmic drugs should be assessed for underlying electrolyte abnormalities as a cause of their refractory dysrhythmia.
