目的比较频谱心电图(FCG)、静态心电图(ECG)和心电向量图(VCG)检出冠心病不稳定型心绞痛(UAP)患者阳性率的比较。方法将162例临床诊断为UAP的患者[均经冠状动脉造影(CAG)证实存在1支或多支病变,至少1支狭窄≥50%]同时进行FCG、ECG、VCG检查,对检查结果依据各自的诊断标准进行判定,然后进行统计学处理。结果①FCG检出的阳性率较ECG、VCG检出的阳性率高(P<0.01);②多支病变组FCG阳性率较单支病变组高(P<0.01);③LVEF<0.50组FCG阳性率较LVEF≥0.50组高(P<0.01)。结论FCG对UAP检出阳性率显著高于ECG和VCG。
Objective To compare the positive rates of patients with coronary heart disease (UAP) detected by spectral electrocardiogram (FCG), static electrocardiogram (ECG) and electrocardiogram (VCG). Methods 162 patients with clinically diagnosed UAP (all with one or more lesions confirmed by coronary angiography (CAG), at least one stenosis ≥50%] were examined for FCG, ECG and VCG at the same time. The diagnostic criteria for the determination, and then for statistical analysis. Results ① The positive rate of FCG detection was higher than that of ECG and VCG (P <0.01). ② The positive rate of FCG in multi-vessel disease group was higher than that in single vessel disease group (P <0.01); ③ The positive rate of FCG in LVEF <0.50 group Higher than LVEF≥0.50 (P <0.01). Conclusion The positive rate of UAP detected by FCG is significantly higher than that of ECG and VCG.
