A 45-year-old woman reports intermittent palpitations and near syncope. A 12-lead ECG demonstrates a prolonged QT interval. Of the following medications she has been prescribed, which may cause QT prolongation and torsades de pointes (ie, polymorphic ventricular tachycardia)?

++
++
++

A. Verapamil

++
++

B. Metoprolol

++
++

C. Metformin

++
++

+

The answer is E.

++
++
++

Which of the following statements is TRUE?

++
++
++

A. The incidence of ventricular fibrillation (VF) at the initial rhythm for in-hospital cardiac arrest is roughly 80%.

++
++

B. Although once the most common initial rhythm encountered with out-of-hospital cardiac arrest, the incidence of VF or pulseless ventricular tachycardia (PVT) is decreasing markedly.

++
++

C. In-hospital cardiac arrest is typically characterized by atrial fibrillation leading to VF.
