The 3-lead tele-ECG demonstrated excellent diagnostic agreement (98%, kappa=0.96, P<0.001) with the conventional 12-lead ECG gold standard in older adults.
Cross-Sectional (n=107)
Does a 3-lead tele-ECG provide comparable diagnostic accuracy to a conventional 12-lead ECG in older people?
A 3-lead tele-ECG provides excellent diagnostic agreement with a conventional 12-lead ECG in older patients, suggesting it is a reliable tool for remote monitoring.
Effect estimate: kappa 0.96
Absolute Event Rate: 98% vs 98%
p-value: p=<0.001
We compared the diagnostic accuracy of 3-lead tele-ECGs to both 12-lead tele-ECGs and a conventional 12-lead ECG device (the gold standard). The subjects were older people (n = 107) with a mean age of 66 years. The overall agreement between two cardiologists on interpreting the 3-lead tele-ECG recordings was 97% (kappa = 0.96, P < 0.001) and it was 91% for the 12-lead tele-ECGs (kappa = 0.90, P < 0.001). We also found excellent agreement on the interpretation of the 3-lead tele-ECGs compared to the gold standard: 98% (kappa = 0.96, P < 0.001) and for the 12-lead tele-ECG compared to the gold standard: 98% (kappa = 0.96, P < 0.001). Bland-Altman plots showed that the apparent differences between the techniques were not clinically relevant. The use of a 3-lead tele-ECG device may be useful for reducing the delay in treating specific heart disease conditions, e.g. in older people affected by chronic heart disease who need frequent ECG monitoring.
Antonicelli et al. (2012) reported a cross-sectional. 3-lead tele-ECG vs. 12-lead tele-ECG and conventional 12-lead ECG was evaluated on Agreement on interpretation compared to the conventional 12-lead ECG gold standard (kappa 0.96, p=<0.001). The 3-lead tele-ECG demonstrated excellent diagnostic agreement (98%, kappa=0.96, P<0.001) with the conventional 12-lead ECG gold standard in older adults.
