[The induction of ventricular fibrillation by transesophageal pacing in subjects with atrial flutter and compromised left ventricular functioning].

In patients with depressed left ventricular function, the normal precautions during transesophageal atrial pacing may not be sufficient to prevent life threatening arrhythmias. In this article two cases of ventricular fibrillation induced during this technique, aimed at treating atrial flutter, are described.
