“…Regression or inconstancy of Q-waves may be seen even as early as one week post-MI [3]. Naturally evolving non-Q-wave Ml would be expected in up to 37% of patients admitted with chest pain and ST segment elevation [4] as compared with 43% of patients who are treated with thrombolytic therapy [5], To our knowledge, no material has been published so far on the dynamic nature of Qwaves during thrombolytic therapy given at the early stages of AMI. In this report, the clinical and electrocardiographic sequence of observations in 4 patients with anterior wall MI canceling preexisting Q-waves during thrombolytic therapy are briefly presented.…”

It is the purpose of this paper to describe the electrocardiographic inconstancy of Q-waves during administration of thrombolytic therapy. This was documented in four patients given streptokinase early in the course of anterior wall myocardial infarction. Understanding the pathogenesis of sequential dynamic variations of Q-waves in this setting may offer important insights into coronary physiology and management of acute coronary events. We discuss the possible explanations for such changes with respect to tissue viability, dynamic vascular changes and electrophysiological properties of the reper-fused infarcted myocardium.
