30例法乐氏四联症患者,男性19例,女性11例,平均年龄13.9岁。均记录常规心电图,经右心导管测量了右心室压力,并得到手术证实。心电图V_1的R波平均17.5mm,右室压力平均110.7mmHg,二者无直线相关(r=-0.117,p>0.05);平均电轴137.4°,与右室压力无直线相关(p>0.05);aVR的R波平均5.7mm,它与右室压力正相关(r=0.630,P<0.001)。右心室压力推算公式为:Y=76.4±5.84×(RavR).
30 cases of tetralogy of Fallot patients, 19 males and 11 females, with an average age of 13.9 years. All ECGs were recorded and the right ventricular pressure was measured by right heart catheterization and confirmed by surgery. The R wave of ECG was 17.5mm on average and 110.7mmHg on the right ventricle. There was no linear correlation between them (r = -0.117, p> 0.05). The mean electrical axis was 137.4 ° and had no correlation with right ventricular pressure (p> 0.05) ; aVR R wave average 5.7mm, it is positively correlated with right ventricular pressure (r = 0.630, P <0.001). The formula of right ventricular pressure is: Y = 76.4 ± 5.84 × (RavR).
