【摘要】 目的 :探讨原发性高血压病人左室重量与 QT间期离散度的关系。方法 :测定 82例原发性高血压病人血压 ,计算 QT间期离散度 (QTcd)及 QTcd%变化与左室重量指数 (L VMI)的关系。结果 :高血压伴左室肥厚 (L VH)组的 QTcd及 QTcd%均明显高于无 L VH组的 ;QTcd及 QTcd%随 L VMI增高而增高 (r=0 .7718,r=0 .6 798) ,但与血压无明显相关性。结论 :高血压病人 QTcd的增加不是血压变化结果 ,而是左室肥厚所致。更多还原

【Abstract】 Objective:To investigate the relationship between left ventricular mass (LVM) and QT dispersion (QTcd) in essential hypertensive(EH) patients.Methods:By measuring blood pressure,QTcd,left ventricular mass index (LVMI) in 82 essential hypertensive patients respectively,the relationship between QTcd and left ventricular hypertrophy (LVH) or LVMI was explored.Results:QTcd and QTcd% in hypertensive group with LVH were significantly higher than those of patients without LVH. Both QTcd and QTcd% were positively correlated with LVMI (r=07718,r=06798),but were irrelevant to blood pressure. Conclusion:QTcd increase is the result of left ventricular hypertrophy,not variation of blood pressure.更多还原
