12导联心电图在肺源性心脏病诊断中的应用观察

Application of 12 lead electrocardiogram in the diagnosis of pulmonary heart disease

目的探讨12导联心电图在肺源性心脏病(pulmonary heart disease,PHD)诊断中的应用价值。方法选取我院2016年4月至2019年3月收治的82例疑似PHD患者,所有患者均行12导联心电图检查,将CR胸片检查结果作为诊断金标准,计算12导联心电图诊断准确度、敏感性、特异性、阳性预测值及阴性预测值,分析PHD心电图的特点。结果经CR胸片检查发现82例患者中有74例确诊为PHD,12导联心电图诊断准确度、敏感性、特异性、阳性预测值及阴性预测值分别为90.24%、91.89%、75.00%、97.14%、50.00%;74例PHD患者经12导联心电图检出异常的有68例,异常类型主要包括肺型P波、电轴偏移、心律失常、低电压、PtfV 1异常、ST-T段改变及顺钟向转位。结论12导联心电图在PHD诊断中具有较高的诊断准确度、敏感性及特异性,对诊断及治疗方案的制定具有较高价值。

Objective To investigate the application value of 12 lead electrocardiogram(ECG)in the diagnosis of pulmonary heart disease(PHD).Methods A total of 82 patients suspected with PHD were selected,who had been admitted in our hospital from April 2016 to March 2019.They all underwent 12 lead ECG examination.The results of CR chest radiography were regarded as the golden standard for PHD.In the diagnosis of the disease,the accuracy,sensitivity,specificity,and positive and negative predictive values of 12 lead ECG were calculated while the ECG characteristics of PHD were analyzed.Results Among the 82 suspects,74 were diagnosed with PHD by CR chest radiography.In the diagnosis of PHD,the accuracy,sensitivity,specificity,and positive and negative predictive values of 12 lead ECG was 90.24%,91.89%,75.00%,97.14%and 50.00%,respectively.ECG abnormalities were found in 68 out of 74 PHD patients by 12 lead ECG testing,mainly including pulmonary P wave,axis deviation,arrhythmia,low voltage,PtfV 1 abnormalities,ST-T segment changes and clockwise rotation.Conclusion The diagnostic accuracy,sensitivity and specificity of 12 lead ECG prove to be high for PHD.It has great value in making plans for diagnosis and treatment.
