摘要
目的观察高血压左心室肥厚者的ＱＴ离散度变化及与左心室肥厚程度的关系。方法１０５例高血压病人和４５例正常人均进行体表心电图和超声心动图检查，测量ＱＴ离散度（ＱＴｄ）和改良法校正的ＱＴ离散度（ＱＴｌｃｄ）。结果高血压左室肥厚组（ｎ＝４２）的ＱＴｄ和ＱＴｌｃｄ明显大于正常对照组（ｎ＝４５）和高血压无左室肥厚组（ｎ＝６３）。高血压病人的ＱＴｄ和ＱＴｌｃｄ与左室心肌重量指数（ＬＶＭＩ）呈正相关（ｒ＝０．４６７，Ｐ＜０．００１；ｒ＝０．４６９，Ｐ＜０．００１）。
Aim\ To study the changes of QT interval dispersion in essential hypertension with left ventricular hypertrophy (LVH) and its correlation with LVH. \ Methods\ 105 hypertensive patients and 43 control persons received 12 lead surface ECG and echocardiogram. The QT dispersion (QTd) and logical corrected QT dispersion (QTlcd) were measured. \ Results\ The QTd and QTlcd in hypertension with LVH( n =42) were significantly broader than in control( n =45) and hypertension with Non LVH( n =63) . The QTd and QTlcd were positively correlated with left ventricular mass index (LVMI) in hypertension ( r=0.467, P <0.001; r=0.469, P< 0.001).\ Conclusion\ The QTd and QTlcd were broader in hypertension with LVH. There were positive relations between the QTd and QTlcd and the severity of LVH in hypertension.
