心电散点图诊断晚发房性早搏的临床应用价值

Clinical application value of ECG scattergram in the diagnosis of late onset atrial premature beat

摘要

摘要:
目的研究心电散点图在晚发房性早搏(APB)诊断中的应用价值。
方法回顾性分析从2017年12月 ~ 2019年5月于我院进行诊治的疑似晚发APB-200例患者，对所有患者均进行心电散点图以及常规心电图检查，对比不同检查方式诊断晚发APB的灵敏度、特异度和准确度。此外，回顾性分析同期我院收治的晚发APB以及窦性心律不齐不明确患者80例，比较心电散点图以及常规心电图的误诊率情况。
结果心电散点图诊断晚发APB的灵敏度为93%、特异度为95%，准确度为94%，相比常规心电图的82%、79%、82%有显著差异（P < 0.05，P < 0.01），心电散点图的漏诊率(7%)和误诊率（5%）显著低于常规心电图（分别18%和21%，均P < 0.05）。
结论心电散点图应用于晚发APB诊断中具有较高的灵敏度、特异度和准确度，较低的漏诊率和误诊率，值得临床推广应用。

Abstract:
AIM To study and analyze the application value of ecg scatter plot in the diagnosis of late onset atrial premature beat (APB).
METHODS From Decembe 2017 to May 2019, 200 patients with suspected late onset APB who were diagnosed and treated in our hospital were selected as subjects for observation. All the patients were examined by electrocardiogram and electrocardiogram, and the sensitivity, specificity and accuracy of late onset APB diagnosed by different examination methods were compared. In addition, 80 patients with delayed APB and unclear sinus arrhythmia admitted to our hospital during the same period were selected to compare the misdiagnosis rate of electrocardiogram scatter plot and routine electrocardiogram. The risk factors of APB was analyzed.
RESULTS The sensitivity, specificity and accuracy of ECG were 93%, 95% and 94% respectively. Compared with 82%, 79% and 82% of conventional ecg, the missed diagnosis rate(7%) and misdiagnosis rate(5%) of ECG were significantly lower than those of conventional ecg(18% and 21% respectively, all P <0.05).
CONCLUSION Electrocardiogram has high sensitivity, specificity and accuracy in the diagnosis of late-onset APB.
