| Panel’s diagnostic ECG category (3-point scale) | Agreement on ECG interpretation | Agreement on management actions | ||
|---|---|---|---|---|
| Number (percentage) assessable for ECG interpretation | Number (percentage) assessable for management implications | Percentage [95% confidence interval] | Percentage [95% confidence interval] | |
| – Normal | 41 (13.8%) | 41 (14.3%) | 90 [81–100] | 93 [84–101] |
| – Borderline | 98 (33.0%) | 96 (33.4%)b | 67 [58–77] | 76 [67–84] |
| – Pathologic | 158 (53.2%)a | 150 (52.3%) b | 61 [54–68] | 66 [58–74] |
| Total | 297 (100%) a | 287 (100%) b | 67 [61–72] | 74 [68–79] |
ECG electrocardiogram
a 3 cases in the category ‘pathologic’ were excluded, because the panel determined the interpretation as ‘not assessable’
b 13 cases were excluded, 2 in the category ‘borderline’ and 11 in the category ‘pathologic’, because the panel determined the management implications as ‘not assessable’
