临床上心电图(ECG)示WPW并BBB者较为少见。我们在168例WPW中发现两例并BBB,其中一例为中间型WPW并右束支传导阻滞(RBBB)。例1 男患,36岁,因心慌、胸闷3年,加重1周就诊。就诊时记录的ECG示:P—P及R—R间期规则,P—R间期为0.07秒;QRS波群明显宽大畸形,除起始部可见明显Delfa波外,Ⅰ、Ⅱ、aVL、V_4—V_6导联,其顶端可见一明显的钝挫,其时限达0.12秒;V_1—V_3S波时限达0.12秒。QRS主波V_1—V_2向下,V_1—V_6向上;Delta波Ⅰ、aVL直立,Ⅱ、Ⅲ、aVR倒置,aVF等电位线。ECG符合B型WPW并左束支传导阻滞(LBBB)。例2 女患,19岁,因头痛、呕吐10余天,加重
Clinical ECG (ECG) showed WPW and BBB are rare. We found two cases with BBB in 168 cases of WPW, one case of intermediate WPW and right bundle branch block (RBBB). Example 1 male patient, 36 years old, due to palpitation, chest tightness for 3 years, an increase of 1 week treatment. The ECG recorded during the visit showed P-P and R-R interphase rules with a P-R interval of 0.07 seconds. The QRS complex was significantly deformed. Except for the obvious Delfa waves at the beginning, I, II, aVL, V_4-V_6 lead, the top visible a blunted, the time limit of 0.12 seconds; V_1-V_3S wave limit of 0.12 seconds. QRS main wave V_1-V_2 down, V_1-V_6 up; Delta wave Ⅰ, aVL upright, Ⅱ, Ⅲ, aVR inversion, aVF equipotential lines. ECG consistent with type B WPW and left bundle branch block (LBBB). Example 2 female suffering, 19 years old, vomiting for more than 10 days due to headache, aggravating
