Electrocardiogram characteristics of different left ventricular geometries in patients with essential hypertension
Objective To investigate the electrocardiogram characteristics of different left ventricular geometries in patients with essential hypertension.Methods 100 patients with essential hypertension in Yue Bei People's Hospital from 2018 to 2021 were selected.According to RWT and LVMI,they were divided into normal morphology group(39 cases),centripetal remodeling group(46 cases),centripetal hypertrophy group(12 cases),and centrifugal hypertrophy group(3 cases).The electrocardiogram parameters of the four groups were measured,and the differences of each group were compared.LVMI and RWT were performed correlation analysis with electrocardiogram parameters,separately.Results ①The voltages of R Ⅰ,R Ⅱ,SaVR,RaVL,SV1,SV2,SV3,RV5,and RV6 in the centripetal hypertrophy group were higher than those in the other three groups(P＜0.05).②The Values of ∑ QRS,R Ⅰ+S m,RV5+SV1,RV6+SV1,RV6+SV2,RaVL+SV3,Cornell index and SD+SV4 in the centripetal hypertrophy group were higher than those in the other groups(P＜0.05).③The Values of R Ⅰ,SaVR,RaVL,SV1,SV2,SV3,RV4,RV5,RV6,R Ⅰ+SⅢ,RV5+SV1,RV6+SV1,RV6+SV2,RaVL+SV3,Cornell index and SD+SV4 were positively correlated with LVMI.The voltages of R Ⅰ,RⅡ,RⅢ,SaVR,RaVL,RaVF,SV1,SV2,SV3,RV5,RV6,RⅠ+SⅢ,RV5+SV1,RV6+SV1,RV6+SV2,RaVL+SV3 and SD+SV4 were positively correlated with RWT.④The proportion of ST-T changes in the centripetal hypertrophy group was higher than the othes.Conclusions Different left ventricular geometries had different electrocardiogram manifestations.Especially in patients with centripetal hypertrophy,there was a higher QRS voltage and a higher incidence of myocardial ischemia.
