Abstract

To the Editor: The association of silent ischemia with sudden cardiac death is well described,1 but has also been disputed.2 A causal relation remains to be established. The induction of ventricular arrhythmias by ergonovine-induced silent ischemia reported by Myerburg et al. (May 28 issue)1 adds to the importance of silent ischemia as a cause of cardiovascular death; nevertheless, the report should be taken with caution. The QT intervals of the patients were not given. There is evidence to suggest that prolongation of the QT interval may identify a group of patients predisposed to sudden death.3 , 4 Haynes et al. found that…
