[Long-term left atrial stimulation by transesophageal approach in complicated biventricular infarction]

The authors report the value of transoesophageal pacing in a 50 year old patient with acute biventricular infarction and cardiogenic shock who developed sinus node dysfunction, junctional rhythm and retrograde atrial activation. This mode of pacing was used permanently for a 48 hour period at a rate of 80/min (atrial capture with a pacing potential of 12 volts and an impulse duration of 12 ms). The clinical results were spectacular and the procedure was well tolerated. This technique can be instituted at the bedside and should be considered in selected cases of sinus node dysfunction when endocavitary pacing is not possible.
