总结778例四联症术前心电图,其特点为:(1)电轴右偏+91°-+180°占99.40%,无电轴左偏者:(2)V_1Rs形突变至V_(2r)S形最常见(58.48%),近半数(42.67%)V_(2-6)均呈rS形。大多数(76.48%)患者V_(5-6)无Q波:(3)胸前导联T波均正向和V_1浅倒伴V_(5-6)正向占87.79%,若T波倒置超过V_3到V_4表示右室心肌弥漫性损害,成年患者多见;(4)除窦性心动过速常见(29.46%)外,其它心律失常非常少见。若紫绀型先心病具上述心电图特点,则四联症诊断可能性大。
Summarize the preoperative ECG of 778 cases of quadruple disease, which is characterized by: (1) right axis deviation + 91 ° - + 180 ° accounting for 99.40%, without left axis deviation: (2) V_1Rs mutation to V_2r The S shape is the most common (58.48%), nearly half (42.67%) V_ (2-6) are rS shape. V (5-6) in the majority of patients (76.48%) did not have Q waves: (3) The positive T wave of the anterior thoracic duct and the positive V_ (5-6) of V_1 were 87.79% positive. More than V_3 to V_4 that diffuse right ventricular myocardial damage, more common in adult patients; (4) in addition to the common sinus tachycardia (29.46%), other arrhythmias are rare. If the cyanotic congenital heart disease with the characteristics of the ECG, the diagnosis of tetralogy of Fall.
