The risk factors for ischemic heart disease are generally known and, in the čase of arterial hypertension, smoking and alcohol abuse are also commensurate with the main etiopathogenetic factors of non-traumatic cerebral haemorrhage. Concurrently, incidents of acute haemorrhagic ictus and acute coronary syndrome are rare in clinical practice. We present the čase of a 61 year old male patient with sudden loss of consci-ousness and circulatory arrest. The cause was extensive subarachnoidal bleeding complicated by ventricu-lar fibrillation concurrently with transitory myocardial ischemia, which manifested as acute coronary syn¬drome with elevated ST segments. We point out the dangers which can arise during the diagnosis and treatment of an unconscious patient with circulatory arrest and stress the cardiac complications attendant with acute cases of subarachnoidal haemorrhage.

        Key words: subarachnoidal haemorrhage, acute coronary syndrome, atrial fibrillation, ischaemic heart disease.
