摘要
目的观察心电图各项电压指标对老年高血压患者心肌肥厚以及心肌肥厚不同几何形态的诊断价值。方法选择入住本院及门诊老年高血压患者86例,根据心脏超声检查结果,将患者分为4组:正常几何形态组(N组,28例)、向心性重构组(CR组,11例)、向心性肥厚组(CH组,25例)和离心性肥厚组(EH,22例)。观察各项心电图电压指标的阳性率。结果各种心电图电压指标均能明显区分正常及异常心脏几何形态,而12导联中,各导联QRS高度之和>175 mm和ⅠR+S>12 mm在CR组(63.6%、54.5%)和CH组(56.0%、72.0%)中的阳性率明显高于EH组(36.4%、31.8%,P<0.05);继发性ST-T改变,CR组(72.7%)和CH组(80.0%)的阳性率明显高于EH组(45.5%,P<0.05)。结论心电图电压指标12导联电压之和>175 mm和Ⅰ R+S>12 mm以及继发性ST-T改变可较好鉴别高血压不同类型心肌肥厚。
Objective To assess the diagnostic values of electrocardiography in left ventricular hypertrophy（LVH） and in predicting the different geometric patterns of hypertrophy in old patients with essential hypertension. Methods Eighty-six patients with essential hypertension were divided into four groups according to the different parameters examined by echocardiography such as left ventricular mass index and relative wall thickness ：normal geometry（N group） ;concentrie remodeling（CR group） ; concentric hypertrophy （CH group） ; eccentric hypertrophy （EH group）. Each patient received a 12-leads electrocardiography, and positive rates of electrocardiographic voltage indexes were observed. Results Various electrocardiographic voltage indexes could differentiate normal and abnormal cardiac geometric patterns,only sum of 12 leads〉175 mm and I R＋ S〉12 mm had significant value in discriminating CR（63.6% and 54. 5%） and CH（56.0% and 72.0%） from EH（36.4% and 31.8%, P 〈 0.05）. In addition,secondary ST-T changes also had significant higher rate in group CR（72.7%） and group CH（80.0%） compared with the group EH （45.5%）. Conclusion The electrocardiographic voltage indexes sum of 12 leads〉175 mm and I R＋S〉12 mm as well as secondary ST-T changes have significant value in discriminating different geometric patterns of LVH.
