Abstract
Proarrhythmia is defined as the generation of new or worsened arrhythmias with drug therapy. Specific proarrhythmia syndromes, each with distinct mechanism and approach to therapy, have been described. The recognized examples are digitalis intoxication, proarrhythmia associated with sodium-channel block, and torsade de pointes (TdP) occurring during QT-prolonging therapies. In addition, because proarrhythmia often seems to develop in the absence of clear risk predictors, a role for genetics in predisposing to this reaction has been postulated. Acquired long QT syndromes (LQTSs) describe pathologic excessive prolongation of the QT interval, with risk for TdP upon exposure to drug therapy. The wide array of drugs with potential for QT prolongation, the large number of patients exposed to such drugs, the difficulty in predicting the risk, and the potentially fatal outcome make acquired LQTS an important public health problem. The best approach to therapy is to identify the patients at risk, to recognize proarrhythmia, to withdraw the offending agents, and to use specific therapies when available.
