title: [Electrocardiographic diagnosis in patients with acute coronary syndrome].
abstract: Electrocardiographic role in a diagnosis of ischemic heart disease has still important value. As important electrocardiographic findings of myocardial ischemia, there are ST elevation or depression, increase high T wave (hyperacute T wave), negative T wave and negative U wave, but it is particularly important to compare those findings and manifestation. Because the patient can always carry it, event ECG is advantageous in that they can record electrocardiography by themselves when they have some symptom. It is necessary to have attention to what abnormal findings of the electrocardiogram which it is easy to be overlooked such as increase T wave or negative U wave appear in early stage of phase of acute coronary syndrome. When the patient has some symptom that acute coronary syndrome is thought about, it is necessary to record electrocardiograms on several times and to do follow up even if there is no electorcardiographic abnormalities at first recording.
