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.
