患者张△△,男,71岁。临床诊断为高血压性心脏病伴心力衰竭Ⅱ度。一、心电图表现图示Ⅱ导心电图。图中可见两大类型的P波。一类P波大体上呈园隆状,形态稍有差异,但其P—P间期稳定(0.46秒),频率130次/分。该类P波后均有QRS波相随,故判为窦性P波。另一类P波形态畸异,尖而窄小,宽为0.05秒类似心房扑动波,其后无QRS波相随,判为异位P。P’—P’间期为1.44～1.58秒不等。窦性P及P’各按自己的节律发放冲动、其中P_3’、P_4’、P_9’形态特别,为伪融合波。另外,窦性P波的形态及P—P间期亦有轻度变
Patient Zhang △△, male, 71 years old. Clinical diagnosis of hypertensive heart disease with heart failure Ⅱ degree. First, the performance of ECG Ⅱ lead electrocardiogram. The figure shows two types of P wave. A class of P wave is generally in the shape of a durometer with slight differences in morphology but with a stable P-P interval (0.46 seconds) and a frequency of 130 beats / min. Such P wave after QRS wave with each other, it is judged as sinus P wave. Another type of P wave morphological abnormalities, sharp and narrow, 0.05 seconds wide similar to atrial flutter wave, followed by no QRS wave phase, sentenced to ectopic P. P’-P ’interval of 1.44 ~ 1.58 seconds. Sinus P and P ’impulse each according to their own rhythms, which P_3’, P_4 ’, P_9’ special shape, as the fake fusion wave. In addition, sinus P wave morphology and P-P interval also mild change
