患者女性,65岁。咳嗽气喘10余年,超声心动图及 X 片均证实右房、右室扩大。临床诊断:肺心病。附图为Ⅱ导联,P 波顺序发生,P-P 间距0.52—0.72s,属窦性心律不齐。P 波形态随频率变化,大部分 P 波形态高尖,达0.28mV,呈肺型 P,但当其前 P-P 间距延长时,肺型 P 转为双峰 P(前峰大于后峰,峰距0.06s),P_4-P_50.55s。当 P_5-P_60.72s 时,P_6双峰;P_6-P_70.60s 时,P_7双峰;P_7-P_8为0.40s;P_8-P_-90.67s 时,P_9双峰;P_9-P_(10)0.60s 时,P_(10)双峰。而当其前 P-P间距缩短时双峰 P 转为肺型 P:P_1—P_5,P-P 间
Patient female, 65 years old. Cough and asthma more than 10 years, echocardiography and X-ray confirmed the right atrium, right ventricular enlargement. Clinical diagnosis: pulmonary heart disease. Figure for the lead II, P wave occurred in sequence, P-P spacing 0.52-0.72s, is a sinus arrhythmia. P wave morphology with frequency changes, most of the P wave shape tip, up to 0.28mV, was pulmonary P, but when the former PP interval is extended, the lung P into double peak P (before the peak is greater than the peak, peak spacing 0.06s), P_4-P_50.55s. When P_5-P_60.72s, P_6 double peak; P_6-P_70.60s, P_7 double peak; P_7-P_8 0.40s; P_8-P_-90.67s, P_9 double peak; P_9-P_ (10) 0.60s When P_ (10) bimodal. When the former P-P spacing shortened when the bimodal P lung type P: P_1-P_5, P-P
