title: Triggered activity as arrhythmogenic mechanism after myocardial infarction: clinical and electrophysiologic study of one case.
abstract: In a woman with an old infarction and sustained ventricular tachycardia, tachycardias were only inducible after short-long RR sequences. After isoprenaline, tachycardias became incessant and all were preceded by short-long RR sequences. This strongly suggests that triggered activity plays a role in initiation of ventricular tachycardias in postinfarction patients.
