Warrants caution with class I agents amid catecholamine surges; hypothesis-generating for proarrhythmic mechanisms post-MI.
Does pretreatment with class 1 antiarrhythmics alter the metabolic, hemodynamic, and electrocardiographic responses to adrenaline in healthy volunteers?
Class 1 antiarrhythmics exacerbate adrenaline-induced metabolic and electrocardiographic changes, providing a potential mechanistic explanation for their proarrhythmic effects and lack of mortality benefit in post-myocardial infarction patients.
Hansen et al. (1991) studied this question.
