患者男性,58岁,因后颈部脂肪瘤于1982年11月入院.既往体健,无器质性心脏病的症状和体征.体检、超声心动图及X线均未见心脏异常.心电图示窦性心律,P-R间期0.10秒,Ⅱ、Ⅲ、aVF、V_1-V_4导联有较典型的预激波,V_5导联出现q波,V_6呈QR型,V_7量QS型(附图).心电图诊断:窦性心律,C型预激综合征.本例心电图P-R间期<0.12秒,多数导联均可见较典型预激波,胸导联V_1-V_4预激波方向向上,此时V_5-V_7导联出现Q波,应考虑为C塑
The patient, male, aged 58, was admitted to hospital for posterior cervical lipoma in November 1982. Previous signs and symptoms of healthy, non-structural heart disease showed no signs of cardiac abnormalities during physical examination, echocardiography, and X-ray. Sinus rhythm, PR interval of 0.10 seconds, Ⅱ, Ⅲ, aVF, V_1-V_4 leads have more typical pre-shock wave, V_5 leads appear q wave, V_6 showed QR type, V_7 QS type (with photos). ECG diagnosis: sinus rhythm, C-WPW syndrome in this case ECG PR interval <0.12 seconds, the majority of lead can be seen more typical pre-shock, chest lead V_1-V_4 pre-shock direction up, then V_5 -V_7 Lead Q wave should be considered as C plastic
