Abstract

ECG signs suggestive of acute coronary syndrome are generally based on the analysis of the repolarization. However, the typical signs can be missing or hidden behind a preexisting abnormality. Thus, is it essential to examine the QRS complexes, whether thin or large, to reinforce a positive diagnosis and specify the stage of ischemia. There are four dynamic signs: the terminal distortion, the absence or the inappropriate R-waves growth, the occurrence of new Q waves and the QRS-complexes fragmentation and their equivalents in case of bundle branch block. Each of these signs provide information on the territory and the severity of ischemia, which may influence the therapeutic.
