Abstract: To explore the relationship between ECG characteristics and disease classification and prognosis for patients with acute cerebral infarction, 110 patients with acute cerebral infarction admitted to neurology department of our hospital from January 2016 to June 2019 were selected as research objects. All patients were given electrocardiogram examination. The abnormal rate of ECG was 72.73%, including ischemic ST-T changes(45.00%), sinus tachycardia(11.25%), ventricular premature beats (11.25%), atrial fibrillation(7.50%), atrial premature beats(6.25%) and left ventricular hypertrophy (6.25%). The abnormal rate of ECG in the slight-group was significantly lower than those in the medium-group and the severe-group (P<0.05). The abnormal rate of ECG in the large and the small infarction groups were significantly higher than those of the lacunar cerebral infarction group (P<0.05). The mortality rate of abnormal ECG group was significantly higher than that of normal ECG group (P<0.05).In conclusion, ECG abnormalities in patients with acute cerebral infarction are mainly manifested as ischemic ST-T changes, sinus tachycardia, ventricular premature beats, atrial fibrillation, atrial premature beats and left ventricular hypertrophy, and the abnormal rate has important evaluating value for disease classification and prognosis.
