一、Romhilt—Estes记分法(RE) 1.QRS高电压:①肢导联R或S波≥20mm;②S_(v1/2)≥30mm和③R_(v5/6)≥30mm(3分)。2.ST—T改变:QRS主波正向导联ST段压低,主波负向导联ST段抬高,伴T波同向改变(未用毛地黄者3分,用毛地黄者1分)。3.左房增大或负荷增加,PtfV_1≤-0.04mm秒(3分)。4.电轴左编≥-30°(2分)。5.QRS时限延长≥0.09秒(1分)。6.VAT延长≥0.05秒(1分)。累积记分≥5分时诊断为左室肥厚。 二、修改Romhilt-Estes记分法(简称修改RE) 1.QRS高电压:R_(v5/6)>26mm,Sv_1+R_(v5/6)>35mm(3分)。2.Tv_6倒置≥1mm(3分)。3.左房增大或负荷增加:PtfV_1≥-0.04mm秒(3分)。4.电轴左偏>-30°(2分)5.QRS时限延长>0.09秒(1分)。6.VAT延长≥0.05秒(1分)。累积记分:≥4分时诊断为左室肥厚。
First, the Romhilt-Estes scoring method (RE) 1.QRS high voltage: ① limb lead R or S wave ≥ 20mm; ② S_ (v1 / 2) ≥ 30mm and ③ R_ (v5 / 6) ≥ 30mm (3 points). ST-T changes: QRS main wave forward lead ST segment depression, the main negative lead ST-segment elevation, with T wave changes in the same direction (without the use of red yellow orange 3 points, with a yellow fox 1 point). 3. Left atrial enlargement or load increase, PtfV_1 ≤-0.04mm seconds (3 points). 4. The left axis of electrical generation ≥ -30 ° (2 points). 5.QRS extended time ≥ 0.09 seconds (1 point). 6.VAT extended ≥ 0.05 seconds (1 minute). Cumulative score ≥ 5 points diagnosed as left ventricular hypertrophy. Second, modify the Romhilt-Estes scoring method (referred to as RE) 1.QRS high voltage: R_ (v5 / 6)> 26mm, Sv_1 + R_ (v5 / 6)> 35mm (3 points). 2.Tv_6 inverted ≥ 1mm (3 points). Left atrial enlargement or increased load: PtfV_1 ≥-0.04mm seconds (3 points). 4. Left axis deviation> -30 ° (2 points) 5.QRS extended time> 0.09 seconds (1 point). 6.VAT extended ≥ 0.05 seconds (1 minute). Cumulative score: ≥ 4 times the diagnosis of left ventricular hypertrophy.
