Effects of alterations in arterial pressure and heart rate on ST-segment elevation in a patient with acute myocardial infarction.
This report describes a 70-year-old male with an anterior transmural myocardial infarction who showed major alterations in the magnitude of ST-segment elevation of his electrocardiogram, when an abrupt change of his heart rate (reduction) and blood pressure (increase) occurred when he reverted to normal sinus rhythm from atrial fibrillation. No concomitant change of other parameters of his clinical status was observed. This report stresses the significance of monitoring serially blood pressure, heart rate, and clinical symptomatology, in addition to electrocardiographic ST-segment elevations in patients with myocardial infarction, when therapeutic interventions aimed at reducing the infarct size are evaluated.
