摘要
目的探讨老年肺心病患者心电图Ｖ１导联Ｐ波终末电势（ＰｔｆＶ１）改变的临床意义。方法１８３例老年肺心病患者治疗前和治疗７～１０天后各查１次心电图１２个常规导联，测定其ＰｔｆＶ１值。结果治疗前ＰｔｆＶ１阳性者为１０１例（５５．２％），治疗后为５８例（３１．７％）（Ｐ＜０．０５）。治疗前ＰａＯ２降低时，ＰｔｆＶ１阳性率增高；左房扩大和（或）左室扩大者ＰｔｆＶ１阳性率较高。结论肺心病患者ＰｔｆＶ１阳性并不少见，且影响因素较多，不宜作为肺心病并存冠心病的诊断依据；但与肺心病的严重程度有关，值得重视。
Objective To evaluate the clinical significance of the change of terminal force of P wave in V1 (PtfV1). Methods One hundred and eighty three elderly patients with cor pulmonale were examined by ECG with 12 standard leads before and after a period of 7 to 10 days treatment to detect the values of the PtfV1. Results The positive rates of PtfV1 before and after treatment were 101(552%) cases and 58(317%) cases respectively. The lower value of PaO2 before treament results in higher positive rate of PtfV1. Positive rate of PtfV1 was higher in the patients with left atrium or(and) left ventricle enlargement. Conclusions The positive PtfV1 in cor pulmonale patients are common and there are many affecting factors. Although the result of positive PtfV1 should not be used as a diagnostic basis for the coexistence of cor pulmonale and coronary heart disease, it should be noted as related to the serious degree of the cor pulmonale.
