A prospective study examining the relationship between psychological distress and ventricular ectopy was conducted with 125 post-myocardial infarction patients equipped with a transtelephonic ECG monitor. Subjects were subsequently grouped according to the occurrence (n = 59) or nonoccurrence (n = 65) of ventricular arrhythmias over a 1-year period. Results indicated a direct relationship between self-reported distress levels and occurrence of ectopic beats. This relationship was unaltered by adjusting simultaneously for known predictors of arrhythmias, including cardiac risk, age, and the prescription of beta-blocker agents. Thus this study represents an initial demonstration in a post-myocardial infarction population that psychosocial factors have prognostic significance for arrhythmias and, presumably, sudden death.
