摘要
对３１例具有病理性Ｑ波的心肌梗塞患者进行了氟－１８标记脱氧葡萄糖正电子发射心肌断层显像（ＰＥＴ／ＦＤＧ），评价心电图（ＥＣＧ）病理性Ｑ波定位的梗死心肌准确性。结果表明：以ＰＥＴ／ＦＤＧ结果为坏死心肌的判断对照指标，ＥＣＧ的病理性Ｑ波定位诊断梗塞坏死区段的灵敏性及阳性预测率仅为６４％及３８％。提示ＥＣＧ的病理性Ｑ波并不能有效而准确地定位诊断梗塞坏死心肌，在ＥＣＧ检查中，多数ＥＣＧ显示的病理性Ｑ波的定位区段仍可能是活性心肌。
To determine whether there was viable myocardium in electrocardiographic pathologic Q wave (ECG Q wave), 31 patients with pathologic Q wave myocaridal infarction were examined by positron emission tomography with F-18-FDG (PET/FDG). Based on the criteria of PET/FDG for necrotic myocardium, the sensitivity and positive predictive rate of ECG Q wave for detecting necrotic myocardium were 64% and 38% respectively. These suggested that the presence of ECG Q wave do not reliably detect necrotic myocardium and the majority of ECG Q wave may be ischemic but viable myocardium.
