本文报告71例60岁以上老年慢性肺心病人的心电向量图表现,并用同时期住院的,病程近似的60岁以下慢性肺心病人作对照。结果:老年组额面向量图QSR电轴有显著右移,右上面积大于全面积20％者、QRS环呈逆钟向旋转者、有左前分支阻滞及左室肥厚表现者较对照组为多,这些差别均有高度显著性(p<0.01)。老年组横面向量图有中度右室肥厚即右后加左前向量大于全面积70％
This article reports 71 cases of elderly patients over the age of 60 with chronic heart disease ECG cardiogram, and with the same period of hospitalization, similar duration of chronic lung disease in patients under 60 as control. Results: In the elderly group, the QSR axis shifted significantly to the right, the upper right area was larger than 20% of the full area, the QRS ring was rotated clockwise, and left anterior branch block and left ventricular hypertrophy were more than those in the control group , These differences are highly significant (p <0.01). The elderly group horizontal vector diagram of moderate right ventricular hypertrophy that is right after plus left front vector is greater than the full area of 70%
