The presenting sign was syncope during exercise. An unusual teature was a right bundle branch block electrocardiographic pattern. During syncope electrocardiograms usually indicated atrial standstill and always had sever ST segment changes indicative of myocardial ischaemia. Pathological findings included chronic valcular changes which did not appear to be the result of a infectious inflammatory condition.en© 1975. The Authors. Licensee: AOSIS OpenJournals.
