Electrocardiography changes in patients with acute myocardial infarction in late hospital phase

One of possibilities to estimate size of myocardial injury during the acute myocardial infarction are electrocardiographic changes, forming of QS formation (ECG signs of scares changes). This investigation which included three groups of patients receiving thrombolytic, nitrates or beta blockers in acute phase of myocardial infarction has aim to analyze 12-chanels electrocardiogram and to establish difference between this therapeutics groups in sum of QRS score, but also to indication frequency of periinfarction heart insufficiency in this therapeutics groups, comparing with observed ECG changes. Analysis shows significant differences between groups in value of QRS score, and also significant lower value of QRS score in patients with acute myocardial infarction treated with thrombolytic therapy. This difference relative to other two groups shows lower level of myocardial injury during acute myocardial infarction in patients treating with thrombolytic therapy.
