Ventricular extrasystoles are:

  • the most common arrhythmias after myocardial infarction and are associated with an increased risk of mortality.
  • attempts to improve survival by suppression of ectopic activity have not been successful.
  • Beta blockers seem better than class 1 antiarrhythmics in improving survival although the ectopics may not be suppressed.

  • The Norwegian Multicenter Study Group (1981). NEJM, 304, 801-7.
