these results indicate that drugs like cocaine and ketamine that interfere with intraneuronal uptake can facilitate the development of epinephrine-induced arrhythmias and that the successive pharmacologic interference of intraneuron uptake , comt , and phosphodiesterase leads to a stepwise increase in the arrhythmogenicity of epinephrine .
