Proarrhythmia is defined as the provocation of new cardiac arrhythmias or the aggravation of preexisting arrhythmias by antiarrhythmic drugs. The possible types of manifestation of proarrhythmia are manifold. With respect to prognosis, drug-induced ventricular tachyarrhythmias seem to be of particular importance. Monomorphic ventricular tachycardia and ventricular tachycardias of the torsade de pointes type have to be distinguished. The former seem to be mainly based on reentrant mechanisms, while the later is supposed to result from triggered activity. Drug-induced monomorphic tachycardia is most often observed during therapy with drugs which slow conduction (class I agents, proarrhythmic potency: IC > IA > IB). Patients with depressed left ventricular function and previously documented life-threatening tachyarrhythmias are the most susceptible candidates. Torsade de pointes can be preferentially observed during therapy with antiarrhythmic drugs which prolong myocardial repolarization (i.e. class IA and class III agents). Electrolyte abnormalities and/or bradycardia are factors which often predispose to the development of this particular type of proarrhythmia. The physician who prescribes antiarrhythmic drugs must be aware of the different types and clinical manifestations of proarrhythmia. This is necessary to assess the degree of proarrhythmic risk and to determine the benefit/risk ratio before the start of drug therapy.
