Abstract

Antiarrhythmic drugs may aggravate or even induce ventricular arrhythmias. This type of adverse reaction is becoming more prevalent as the use of antiarrhythmic agents becomes more widespread. In a retrospective analysis of antiarrhythmic drug action, a worsening of arrhythmia was observed in 80 of 722 (11.1%) antiarrhythmic drug tests in 53 of 155 patients being treated for ventricular tachyarrhythmias. Aggravation of arrhythmias was defined by occurrence of a fourfold increase in the frequency of ventricular premature complexes, a 10-fold increase in repetitive forms, or the first emergence of sustained ventricular tachycardia coincident with time course of action of the particular drug under study. Such aggravation was noted with each of nine drugs tested: quinidine, procainamide, disopyramide, propranolol, metoprolol, aprindine, mexiletine, tocainide and pindolol. The frequency of this complication for a specific drug ranged from 5.9-15.8%. Blood drug concentrations were consistently in the therapeutic range. A study of the variability of ventricular arrhythmia during 48-hour Holter monitoring and exercise stress testing in no instance showed arrhythmia enhancement commensurate with that defining aggravation. Our data suggest that this potentially serious complication is not readily predictable and requires a systematic approach to antiarrhythmic drug testing before a patient is prescribed a long-range maintenance program.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
