[Cardiovascular involvement and complications in Mediterranean boutonneuse fever]

After a review of the literature on heart damage in rickettsiosis, the data from a clinical and ecgraphic investigation of 17 patients suffering from boutonneuse fever are reported. There was little cardiovascular involvement and inconstant hypotension but two heart complications are described, one myocardial ischaemia which cleared up a few days after the end of the diseases, and an atrial fibrillation that lasted two days. Stress is laid on the need for constant ecgraphic monitoring, even in this minor rickettsiosis.
