患者,女,40岁。风湿性心脏病、二尖瓣窄、心功能Ⅱ级入院。心电图:Ⅱ导联,窦性心律,P—P 间期与 R—R 间期匀齐,基本固定为1.08S。两种形态 P 波:P_(1、2、3、4、)高尖,呈“肺性 P 波”。振幅5mm;时限0.08S。P_(5、6、7、8)小尖峰伴切迹。振幅2mm;时限0.10S。心电图见 P 波的振幅有明显的变化,而无频率的改变,其中它们的P—R 间期匀等于0.14秒。因此可除外起搏点的变异及房性异位节律。此例符合不完全性右房内间歇性阻滞的表现。
Patient, female, 40 years old. Rheumatic heart disease, mitral valve narrow, cardiac function Ⅱ admission. ECG: Ⅱ lead, sinus rhythm, P-P interval and R-R interval uniform, the basic fixed 1.08S. Two forms of P wave: P_ (1,2,3,4,) high tip, was “pulmonary P wave.” Amplitude 5mm; time limit 0.08S. P_ (5,6,7,8) spike with notch. Amplitude 2mm; time limit 0.10S. The amplitude of the P wave in the electrocardiogram showed a marked change with no change in frequency, where their P-R interval equaled 0.14 seconds. Therefore, except for the variation of pacemaker point and atrial ectopic rhythm. This case is consistent with incomplete intra-atrial intermittent block performance.
