右位心伴心室肥大较少,报告2例。 例1 男,14岁。自幼口唇指端发绀。体检示心尖搏动位于胸部右下方,X线呈镜面右位心,紫绀型先天性心脏病法乐氏四联症。心电图示(图略)Ⅰ导联P波倒置,QRS波呈“R”型,将它镜面观为正常心脏的直立P波和QRS波呈QS型,Ⅰ与Ⅱ导联(相当于正常Ⅲ导联)。查得心电轴+145°,aVL相当于aVR,故aVL高达0.9mV。V_2、V_3RV_5R相当于正常心脏的V_1、V_3、V_5。结合临床,超声心动图及X线所见,心电图诊断为右位心伴右心室肥大。
Right heart with ventricular hypertrophy less, 2 cases were reported. Example 1 male, 14 years old. Since his lips lip cyanosis. Physical examination showed apical beats in the lower right chest, X-ray was a mirror of the right centripetal cyanotic congenital heart disease tetralogy of Fallot. ECG lead (Figure omitted) Ⅰ lead P wave inversion, QRS wave was “R” type, the mirror view of the heart of the normal P wave and QRS wave QS type, Ⅰ and Ⅱ leads (equivalent to the normal guide United). Check the ECG axis +145 °, aVL is equivalent to aVR, so aVL up to 0.9mV. V_2, V_3RV_5R is equivalent to the normal heart V_1, V_3, V_5. Combined with clinical, echocardiographic and X-ray findings, ECG diagnosis of right concentric heart with right ventricular hypertrophy.
