Considering many case histories, we realized that symptoms and clinical signs of acute poisoning are mostly neurologic: coma, headache, dizziness, vomiting. On the contrary, it seems that myocardium, the other organ which mostly requires O2, is attacked in a "silent way". ECG in 5 patients with accidental carbon monoxide poisoning underlined that cardiac rate increased (3 of them presented tachyarrhythmias by atrial fibrillation) and the presence of more or less important alteration of ventricular repolarization like "subendocardial lesion". Simple hyperbaric oxygen treatment determined the regression of the rhythm disorder and of the abnormalities of ventricular repolarization. The only patient who had not the restoration of sinus rhythm had chronic atrial fibrillation.
