患者男性53岁,临床诊断:风湿性心脏病,二尖瓣狭窄,心功能Ⅱ—Ⅲ级。心电图(附图)示Ⅰ导联 P、QRS、T 波倒置,将它镜面观察为正常Ⅰ、Ⅱ、Ⅲ导联互换,aVR、aVL 导联互换。胸导联自 V_1—V_6导联的 R 波与 S 波逐渐缩小,加作 V_2、V_(3R)、V_(4R)、V_(5R)则相当于正常心脏的 V_1、V_3、V_4、V_5导联,符合真正右位心的心电图特征。P 波:Ⅱ、Ⅲ、aVF 直立呈双峰,后峰大于前峰,P 波时限0.12s,为典型二尖瓣型 P 波。P-R 间期0.12s,QRS 波群时限
Male 53 years old, clinical diagnosis: rheumatic heart disease, mitral stenosis, cardiac function Ⅱ-Ⅲ level. ECG (with photos) shows Ⅰ leads P, QRS, T wave inversion, it is specularly observed as normal Ⅰ, Ⅱ, Ⅲ lead exchange, aVR, aVL lead interchangeable. The R wave and S wave of the lead of V 1 -V 6 lead to a decrease in the lead of chest lead, which is equivalent to V 1, V 3, V 4, V 5 lead of V 6, V 3R, V 4R and V 5R of normal heart Union, in line with the true right ambition ECG features. P wave: Ⅱ, Ⅲ, aVF showed a bimodal upright, posterior peak greater than the former peak, P wave duration 0.12s, as a typical mitral-type P wave. P-R interval 0.12s, QRS wave group time limit
