患者女性,54岁,临床诊断:冠心病,心律失常。附图(见第103页)为V_1导联连续记录,示窦性P波,频率50次/分,QRS呈rS形,P-R间期0.10秒,诊断窦性心动过缓,L-G-L综合征。另见提早、略变形的P′波,配对间期0.40秒(除下行R_3外),代偿间期1.10秒,皆较窦律周期1.18秒短。早搏呈CLBBB时(上行R_8和下行R_(1、8)),其P′-R长达0.26—0.30秒;呈CRBBB时(上行R(2、5)和下行R_3),除下行R_3外,P′-R长0.23秒,部
Female patient, 54 years old, clinical diagnosis: coronary heart disease, arrhythmia. The figure (see page 103) for V_1 lead continuous recording, showing sinus P wave, frequency 50 beats / min, QRS was rS-shaped, P-R interval of 0.10 seconds, diagnosis of sinus bradycardia, L-G-L syndrome. See also earlier, slightly deformed P ’wave, pairing interval of 0.40 seconds (except R_3 downstream), compensatory interval of 1.10 seconds, are shorter than the sinus law cycle 1.18 seconds. When the premature beat was CLBBB (up R_8 and down R_ (1,8)), the P’-R was as long as 0.26-0.30s; while in the case of CRBBB (up R (2,5) and down R_3) P’-R 0.23 seconds, min
