Rapid atrial fibrillation following tube thoracostomy insertion.

We report a case of trauma patient, whose heart rhythm and rate changed from sinus tachycardia to rapid atrial fibrillation. The change occurred immediately after the insertion of left thoracostomy tube. The patient did not respond to pharmacological treatment. Only when the tube was pulled out, the rhythm returned to sinus. Chest radiogram shows the position of the tube, in close proximity to the cardiac silhouette.
