Key result
Programmed ventricular stimulation inducing tachyarrhythmias (in 23% of patients) did not significantly predict sudden death or spontaneous ventricular tachycardia during a 10-month follow-up.

Inducibility should not guide post-MI sudden death risk stratification; leaves open whether it adds value in larger prospective cohorts.

Does programmed ventricular stimulation identify a high risk for sudden cardiac death in survivors of acute myocardial infarction?
Induction of ventricular tachyarrhythmias during programmed ventricular stimulation does not identify a high-risk group for sudden cardiac death among survivors of acute myocardial infarction.
Roy et al. (1985) conducted a cohort in Acute myocardial infarction (n=150). Programmed ventricular stimulation vs. No inducible ventricular tachyarrhythmias was evaluated on Sudden death, nonsudden death, and sustained ventricular tachyarrhythmias. Programmed ventricular stimulation inducing tachyarrhythmias (in 23% of patients) did not significantly predict sudden death or spontaneous ventricular tachycardia during a 10-month follow-up.
