It is reported ' The intersection of reporter and beautiful sesame Guo red in Yan) Chinese Medical Sciences University attaches to researchers of holding Beijing hospital professor's ox iron to grow etc., in raise in the myocardium infarction finding excited to delay wave section ST, named as " the intersection of N and wave " it for the first time . This finds that has important value to the diagnosis and treating of myocardium infarction. This research results are published on the important magazine " international heart disease magazine " in the field of international cardiology recently. According to admitted to hospital electrocardiogram, divide into, it raises myocardium infarction for section ST to be and that the section ST raise myocardium infarction acute myocardium infarction. But in raise in the myocardium infarction section ST, the intersection of electrocardiogram and characteristic and relation between the infarction relevant artery so obvious. In the former research, raise or force down while being concerned. By contrast, the acute myocardium infarction patient is admitted to hospital QRS wave shape of the electrocardiogram, arouse attention, the section ST of the special right and wrong raises myocardium infarction. Ox iron grow, it studies groups to be section ST raise the myocardium infarction patient go on research to 218, find left circle round pieces of artery a acute to hard to get one section ST raise myocardium electrocardiogram, patient of infarction, have one strange phenomenon that report to before finally: Lead, unite the intersection of QRS and the intersection of wave and group, end some in ��, AVF or, the intersection of AVL5 and kind, often present a turn or make sure to keep in mind, there are constantly changeable characteristics, even turn into S wave. Meanwhile, an obvious extension among QRS. The article names this kind of phenomenon " N wave " . Research reveal the intersection of N and wave and circle round criminal's pathological change, have higher specificity and good sensitivity. Researchers draw the conclusion finally, N wave is that the excitement in the basal area of left ventricle delays the wave. It is a kind of new ischemic electrocardiogram mode that excited to delay the wave. If section ST raise myocardium infarction patient have excited to delay wave, circle round criminal's pathological change have relatively high acute hard to getting rate, so even classical section ST raise and new the intersection of left and bunch prop up block, exist, also the section ST raises myocardium infarction, should do the radiography of coronary artery as soon as possible, and implement coronary artery and rebuild the operation.
