患者女性,30岁,临床诊断:风湿性心脏病,二尖瓣狭窄伴关闭不全5年余。因劳累、心悸、胸闷、气短于1986年12月20日就诊。附图(见第104页)Ⅱ导联连续记录示P波形态有3种:1.直立圆钝的窦性P波(P_(11-15));2.逆行P-波固定于R波之后(P_(1、3、5、7、9、12-14、16)~-);3、形态介于上述两者之间的房性融合波(P’_(2、(?)、8、10))。细加测量P_(11)-P_(15)与P’_2-P’_(?)间距相等(4.52秒),也为P’_(?)-P’_3或P’_(?)-P’_(1(?))间距(2.26秒)的2倍,P’_3-P’_(10)间距大于P/_(10)-P_(11)间距2倍,(在先不考虑窦房传导障碍的情况下),P’_(10)-P_(11)应是显示的最短窦性间距。窦房干扰性脱节时推算窦性周期长度的公式为长P-P/P’数+1故本例为4.52秒/3+1=1.13秒频率为53次/分。
Female patient, 30 years old, clinical diagnosis: rheumatic heart disease, mitral stenosis with incomplete closure more than 5 years. Due to fatigue, palpitations, chest tightness, shortness of breath on December 20, 1986 treatment. There are three types of P wave morphology recorded continuously in the Ⅱ lead (see page 104): 1. an upright blunt sinus P wave (P_ (11-15)); 2. a retrograde P wave fixed to an R wave (P_ (1, 3, 5, 7, 9, 12-14, 16) ~); 3, Atrial fusion between the above two 8,10)). The fine addition P_ (11) -P_ (15) is equal to P’_2-P’_ (?) Spacing (4.52 seconds) and is also P’_ (?) - P’_3 or P’_ (?) - The P’_3-P’_ (10) spacing is more than twice the pitch of P / _ (10) -P_ (11), without prior consideration Sinoatrial conduction disorder), P ’_ (10) -P_ (11) should be the shortest sinus spacing shown. The sinoatrial disruption disjunction deduced sinus cycle length formula for the long P-P / P ’number +1 so this example is 4.52 seconds / 3 +1 = 1.13 seconds frequency of 53 beats / min.
