[Electrocardiographic and arterial pressure changes in the acute phase of subarachnoid hemorrhage].

A prospective study was made of 30 patients, admitted to the neurology ward with subarachnoidal hemorrhage (SAH), at its onset. The diagnosis was established on the basis of anamnesis, clinical examination, spinal puncture, anatomopathological examination. The patients with other cerebrovascular affections or with antecedents of ischaemic cardiac affections were excluded. ECG tracings, serum ionogram, AT and VA at the onset and in evolution, and their modifications were followed and assessed in all the patients. The conclusion is reached that SAH in acute phase is associated with transitory ECG and pressure anomalies which become elements of unfavourable prognosis when persistent and deeply altered. They are valuable, at hand, elements in the differential diagnosis, and in the opportune therapeutical intervention.
