Increased incidence of (−)-adrenaline-evoked arrhythmias by rolipram (a) and blockade by CGP20712A (b). %Arrythmias is the % of ventricles that showed extrasystoles and/or ventricular tachycardia at each (−)-adrenaline concentration. Lines depict the dependence of arrhythmias on −log(−)-adrenaline concentration. The slopes of the lines were 0.126 and 0.096 in the absence and presence of rolipram, respectively. B, basal; ISO, (−)-isoprenaline 200 μM;R, rolipram.
