高血压病患者左室构型与心室晚电位的关系

Relation between the left ventricular pattern and ventricular late potential in hypertensive patients

目的 了解高血压病患者左室构型与心室晚电位 (VLP)之间的关系。方法 应用超声心动图及信号平均心电图 ,测定 110例高血压病患者的左室构型和心室晚电位阳性率。结果 检出VLP阳性 19例( 17 3 % ) ,高血压伴左室肥大 (LVH)者VLP阳性检出率 3 0 2 % ,显著高于无LVH者 5 3 % (P <0 0 0 1)。其中 2 3例离心性左室肥厚者VLP阳性 8例 ( 3 4 8% ) ,3 0例向心性肥厚者VLP阳性 8例 ( 2 6 7% ) ,12例向心性心室重构者VLP阳性 2例 ( 16 7% ) ,正常构型者VLP阳性 1例 ( 2 2 % )。

Objective To survey the relation between the left ventricular pattern and ventricular late potential (VLP) in hypertensive patients.Methods 110 patients with hypertension were studied by Doppler echocardiography and KOW-1801 instrument.Results The positive incedence of VLP was 17.3% in 110 hypertensive patients and 30.2% in patients with left ventricular hypertrophy ( P <0 001). The incedence of VLP was 34.8% in 23 patients with eccentric hypertrophy, 26.7% in 30 patients with concentric hypertrophy, 16.7% in 12 patients with concentric remodeling and 2.2% in 45 patients with normal pattern. Conclusion The left ventricular pattern is obviously correlated to ventricular late potential.
