correlative study of changes of plasma calcium and Q-T interval during acute non complicated transmural myocardial infarction

ABSTRACT

Twenty patients and ten healthy persons were the candidates of this study. Patients were selected to have recent non-complicated transmural myocardial infarction. The aim of the present work was to define the Q-T interval changes and also changes in plasma calcium during the acute infarction. Results showed significant prolongation of Q-T interval of patients compared to controls from the first day post infarction up to the fifth day with maximal prolongation in the third day. Patients showed significant fall in plasma calcium and albumin. When a correcting factor was applied to convert the measured calcium to the values that would be expected at a fixed albumin concentration it showed insignificant hypocalcemia
