Electrocardiographic (ECG) and vectorcardiographic (VCG) QRS voltage criteria have been analyzed in 26 patients with inferior and 17 with posterior myocardial infarction (MI) in comparison with left ventricular (LV) mass and global and regional wall motion as assessed by M-mode and two-dimensional (2D) echocardiography. Transverse plane QRS maximal vector correlated significantly with LV mass in patients with both inferior and posterior MI (r = 0.65 and 0.87, respectively, p less than 0.01). A transverse plane QRS maximal vector greater than 1.5 mV correctly recognized 12 of 15 (80%) and 9 of 12 (75%) patients with respectively inferior and posterior MI and LV mass greater than 221 gm. Of the ECG measurements, S V1-2 + R V5-6 correlated moderately with LV mass in patients with inferior MI (r = 0.47), and R V1-2 + R V5-6 correlated moderately with LV mass in those with posterior MI (r = 0.67). ECG and VCG QRS voltage data did not correlate with global and regional LV function as assessed by M-mode and 2D echocardiography. We conclude that: ECG and VCG QRS voltage parameters can be utilized for assessing non-invasively LV enlargement in patients with postero-inferior MI; ECG and VCG QRS voltage parameters should be utilized with caution for analyzing LV function or MI size in postero-inferior MI.
对26例下壁心肌梗死患者和17例后壁心肌梗死患者的心电图（ECG）和向量心电图（VCG）QRS电压标准进行了分析，并与通过M型和二维（2D）超声心动图评估的左心室（LV）质量以及整体和局部室壁运动进行了比较。下壁和后壁心肌梗死患者的横面QRS最大向量与LV质量显著相关（分别为r = 0.65和0.87，p < 0.01）。横面QRS最大向量大于1.5 mV时，分别正确识别出15例下壁心肌梗死且LV质量大于221 g患者中的12例（80%）以及12例后壁心肌梗死且LV质量大于221 g患者中的9例（75%）。在ECG测量中，下壁心肌梗死患者的S V1-2 + R V5-6与LV质量中度相关（r = 0.47），后壁心肌梗死患者的R V1-2 + R V5-6与LV质量中度相关（r = 0.67）。ECG和VCG QRS电压数据与通过M型和2D超声心动图评估的LV整体和局部功能不相关。我们得出结论：ECG和VCG QRS电压参数可用于无创评估下后壁心肌梗死患者的LV扩大；在分析下后壁心肌梗死患者的LV功能或心肌梗死大小时，应谨慎使用ECG和VCG QRS电压参数。
