ABSTRACT
The use of adenosine has been suggested as a diagnostic tool in the evaluation of wide ORS complex tachycardia. However, adenosine shortens the antegrade refractoriness of accessory atrioventricular connections and may cause acceleration of the ventricular rate during atrial fibrillation. We observed ventricular fibrillation in 2 patients who presented to the emergency department with pre-excited atrial fibrillation and were given 12 mg of adenosine.

Acquired tracheo-oesophageal fistula is rare. The most common causes are tuberculosis and malignancy. Here we report a patient who had come with dysphagia and aspiration pneumonia with paratracheal lymphnodes on X-ray chest and was diagnosed to have a tracheo-bronchial fistula on barium studies. Transtumoral intubation by pull-through method was carried out.
