VL nó là có thể xảy ra tắc nghẽn của động mạch ở phần giữa của LAD thấp sau khi đường chéo thứ hai đầu tiên và cũng là ngành vách ngăn đầu tiên. Điều này giải thích rằng nhồi máu cơ tim với sóng Q trong precordials nhưng không phải trong tôi và VL thường rất rộng lớn | 102 Chapter 11 VL it is probable that the occlusion of the artery is in the mid-low part of LAD after first-second diagonal and also the first septal branches. This explains that myocardial infarctions with Q waves in precordials but not in I and VL are often not very extensive apical MI 51 52 and involve only the mid-low part E opium and anterior wall and usually also the apex because the LAD islongand wraps theapex segment 17 57 The correlation between CMR and ECG patterns has allowed US to realize that there are seven ECG patterns that match very well with seven ECG areas of necrosis located in different areas of the left ventricle. This is the basis of our new classification of Q-wave MI that we will explain later on Table 15 33-3 5 Finally the recent consensus regarding the diagnosis of infarction by the ELC ACC European SosietyafCardiology AmericanCollogeof CardioIggy 49 50 accfnteCOe diagnosisaO intfec ion ir roponin levateincrease accamf penieObyanyofCOaother criieeia liotadm Table 5 rao sa eauirino tEe arssensa tneec aro Infarotionr tha mvnivelosn than ilteamnllntd necroiia tissue ncraedtomoOifythe E CG en .0Oirimpiirs Cs t mrmormsSableanginas are turned into infarctions microinfarctions or necrosettes .
