View larger version (30K): [in a new window]   Figure 1 Arrhythmia incidence during no-drug control (left), ephedrine treatment (middle), and drug washout (right). The 60% increase in arrhythmia incidence during ephedrine therapy was significant (p < 0.02). PVC = premature ventricular contractions; VF = ventricular fibrillation; VT = ventricular tachycardia.
