摘要: 背景远程心电云平台对心血管疾病防治具有积极的底层支撑作用。在探索应用人工智能(AI)技术协同医生更好地判读心电图的同时,如何优化诊断流程、提高危急值心电图诊断时效性是研究者在远程心电云平台建设中必须关注和解决的问题。目的探讨AI在远程心电云平台辅助决策基层危急值心电图中的应用价值。方法选取2019年6月至2021年6月基层医疗卫生机构采集并上传至纳龙远程心电云平台的20 808份12导联静态心电图,同时经AI(AI组)诊断和专业心电图医生(医生组)诊断后,将符合危急值心电图诊断标准的心电图纳入危急值组,符合正常心电图诊断标准的心电图纳入正常组,结果虽异常但不符合危急值心电图诊断标准的心电图纳入阳性组。以医生组诊断结果作为金标准,统计AI组与医生组诊断的一致性、符合率及AI组诊断的灵敏度、阳性预测值,统计各组心电图诊断用时。结果AI组诊断的危急值组、阳性组、正常组心电图分别为619、15 634、4 555份;医生组诊断的危急值组、阳性组、正常组心电图分别为619、15 759、4 430份。AI组与医生组诊断具有强一致性〔Kappa值=0.984,95%CI(0.982,0.987),P<0.001〕;两组诊断符合率为99.4%;AI组诊断灵敏度为99.4%,阳性预测值为100.0%。危急值组、阳性组、正常组的诊断平均用时比较,差异有统计学意义(P<0.001),其中危急值组诊断平均用时较阳性组、正常组短(P<0.001)。结论AI应用于远程心电云平台中,不但可协助医生判读心电图,提高诊断的准确性,还可优化诊断流程,缩短危急值心电图诊断用时,有助于基层危急重症患者的救治。

Abstract: Background

The cloud-based platform for electrocardiography (ECG) analysis plays a supporting role in the prevention and treatment of cardiovascular diseases. During the construction of a cloud-based platform for ECG analysis, problems that should be focused and addressed are exploring ways to better use artificial intelligence (AI) technologies supporting ECG analysis, and improving the process and effectiveness of AI-aided diagnosis of a critical ECG.

Objective

To explore the use of AI technologies in a cloud-based platform for ECG analysis to support the diagnosis of a critical ECG in primary care.

Methods

The 12-lead resting ECGs (n=20 808) uploaded to Nalong Cloud-based ECG Analysis Platform by primary healthcare institutions were selected from June 2019 to June 2021. After being interpreted by AI-based algorithms and physicians, respectively, ECG findings were classified into critical group (critical ECGs) , normal group (normal ECGs) , and positive group (abnormal but not critical ECGs) . The results interpreted by the AI-based algorithm were compared with those interpreted by physicians (defined as the gold standard) to assess the diagnostic agreement and coincidence rate between AI-based and physician-based interpretations, and to assess the diagnostic sensitivity, and positive predictive value of AI-based interpretation. And the mean time for making diagnoses of three groups of ECGs was calculated.

Results

By the AI-based interpretation, 619, 15 634 and 45 55 ECGs were included in the critical, positive, and normal groups, respectively. And by the physician-based interpretation, 619, 15 759 and 4 430 ECGs were included in the critical, positive, and normal groups, respectively. There was high agreement between AI-based and physician-based interpretation results of ECGs〔Kappa=0.984, 95%CI (0.982, 0.987) , P<0.001〕, with a diagnostic coincidence rate of 99.4%. The diagnostic sensitivity and positive predictive value of AI-based interpretation for ECGs was 99.4%, and 100.0%, respectively. The mean time for making diagnoses of critical ECGs, abnormal but not critical ECGs, and normal ECGs was statistically different (P<0.001) , the mean time of critical critical ECGs was shorter than normal ECGs and abnormal but not critical ECGs (P<0.001) .

Conclusion

AI technologies used in a cloud-based platform for ECG analysis could provide physicians with support for interpreting ECGs, which may contribute to improving the interpretation accuracy, optimizing the diagnostic process, shortening the time for diagnosing a critical ECG, and the treating of critical patients in primary care.
