Cardiogoniometry (CGM) is a spatio-temporal five-lead resting electrocardiographic method utilizing automated analysis. The purpose of this study was to determine CGM's and electrocardiography (ECG)'s accuracy for detecting myocardial ischaemia and/or lesions in comparison with perfusion cardiac magnetic resonance imaging (CMRI) and late gadolinium enhancement (LGE).
Forty (n= 40) patients with suspected or known stable coronary artery disease were examined by CGM and resting ECG directly prior to CMRI including adenosine stress perfusion (ASP) and LGE. The investigators visually reading the CMRI were blinded to the CGM and ECG results. Half of the patients (n= 20) had a normal CMRI while the other half presented with either abnormal ASP and/or detectable LGE. Cardiogoniometry yielded an accuracy of 83% (sensitivity 70%) and ECG of 63% (sensitivity 35%) compared with CMRI.
In this pilot study CGM compares more favourably than ECG with the detection of ischaemia and/or structural myocardial lesions on CMRI.
心脏测功法（CGM）是一种时空五导联静息心电图方法，利用自动化分析。本研究的目的是确定 CGM 和心电图（ECG）在检测心肌缺血和/或病变方面的准确性，与灌注心脏磁共振成像（CMRI）和延迟钆增强（LGE）进行比较。
40 名（n=40）疑似或已知稳定型冠状动脉疾病患者在 CMRI 检查前直接进行 CGM 和静息 ECG 检查，包括腺苷应激灌注（ASP）和 LGE。对 CMRI 进行视觉阅读的研究人员对 CGM 和 ECG 结果不知情。一半的患者（n=20）CMRI 正常，而另一半患者出现异常的 ASP 和/或可检测到的 LGE。与 CMRI 相比，心脏测功法的准确性为 83%（敏感性 70%），心电图为 63%（敏感性 35%）。
在这项初步研究中，CGM 在检测 CMRI 上的缺血和/或结构性心肌病变方面比心电图更有优势。
