患者男性,27岁,1985年11月因心前区不适、气短、乏力,心电图检查发现Ⅰ°A-VB。1986年3月以来多次心电图检查P-R间期正常,或延长至0.34-0.50秒,有时则表现为Ⅱ°一型A-VB。 1986年8月心电图示:Ⅰ、Ⅱ导联P-P间隔0.90—0.96秒,P-R间期0.22秒,V_1-V_5P-P间隔0.90—0.96秒,P-R间期0.40—0.44秒,aVF导联的P_1 -R0.16秒,P_2 -R0.20秒,P_3-R0.22秒,P_4-R突然延长到0.50秒(附图,见第237页),连续19个(此处刊出5个——编者长P-R间期,无QRS脱落,考虑快径路内文氏现象,逐渐延长直至传导
Male patient, 27 years old, November 1985 due to precordial discomfort, shortness of breath, fatigue, ECG found Ⅰ ° A-VB. Since March 1986, multiple electrocardiography P-R interval between normal, or extended to 0.34-0.50 seconds, and sometimes showed Ⅱ ° a type A-VB. August 1986 ECG: Ⅰ, Ⅱ lead PP interval 0.90-0.96 seconds, PR interval 0.22 seconds, V_1-V_5P-P interval 0.90-0.96 seconds, PR interval 0.40-0.44 seconds, aVF lead P_1 - R0.16 seconds, P_2 -R0.20 seconds, P_3-R0.22 seconds, P_4-R suddenly extended to 0.50 seconds (with photos, see page 237), 19 consecutive Long PR interval, no QRS shedding, considering fast path Wen’s phenomenon, gradually extended until conduction
