2、厚(concentrichypertrophy,CH);¼离心性肥厚(eccentrichypertrophy,EH),观察心电图Cornell指数在各组中的阳性率。结果:Cornell指数均能明显区分正常心脏形态及左心室肥厚;在不同左室肥厚构型中,Cornell电压指数>218mV(男)和Cornell电压指数>210mV(女)以及Cornell乘积指数>2440mm/ms能够显著区分CH(阳性率分别为88%、85%和82%)和EH(阳性率分别为62%、60%和62%)(P<0101);Cornell乘积指数>2440mm/ms(在CR组的阳性率(80%、7
3、5%)明显高于EH组(62%、40%)(P<0101)。结论:心电图Cornell电压指数及Cornell乘积指数可较好鉴别高血压病左室肥厚的不同几何构型。关键词:Cornell指数;高血压,原发性;心肌肥厚中图分类号:R544.1;R540.41文献标识码:A文章编号:1009-7236(2010)06-871-03ValueofCornellindexindiagnosisofleftventricularhypertrophyinpatientswithessentialhypertensionDONGXin,ZHANGLin,FANYan-mei,QI
