患者男性,69岁。临床诊断:慢性肺原性心脏病、急性支气管感染。患者于1987年1月12日入院,第3天心电图记录(附图,见第36页)上行为窦性心律,心律匀齐,心律100次/min,P 波高约0.22—0.25mV,大于 R 波的1/2,形态尖锐,为“肺型 P 波”。下行 P 波大多埋没在 QRS 波之中,部分 P 波在 QRS 起始前,P 与 QRS 呈分离状态。P-P与 R-R 周期皆为0.52s,约合心律115次/min,唯 R_5-R_6仅有0.50s,说明 R_6是提前发
Male patient, 69 years old. Clinical diagnosis: Chronic pulmonary heart disease, acute bronchial infection. The patient was admitted to hospital on January 12, 1987 and on the third day of electrocardiographic recording (Figure 36), sinus rhythm, uniform heart rate, heart rate 100 beats / min, P wave height about 0.22-0.25 mV, greater than R Wave 1/2, sharp shape, as “pulmonary P wave.” Downward P wave mostly buried in the QRS wave, part of the P wave before the beginning of QRS, P and QRS were separated. P-P and R-R cycles are 0.52s, about rhythm 115 times / min, the only R_5-R_6 only 0.50s, indicating that R_6 is advanced
