Transoesophageal cardiac pacing.

An elderly patient, whilst undergoing anaesthesia for a total hip replacement, developed a marked bradydysrhythmia suggestive of sick sinus syndrome. The heart rate was unaffected by atropine 1.2 mg administered intravenously. Cardiac pacing was achieved by means of a non-invasive transoesophageal pacemaking catheter. The simplicity of this technique although temporary, is ideal for emergencies.
