Evaluation of the accuracy of QTc measurements between paired methods.
| GS vs telemetry (CL) | GS vs telemetry (TF) | GS vs telemetry (TS) | GS vs telemetry (average) | |
|---|---|---|---|---|
| Mean difference (95% CI) (ms) | 10.9 (6.5, 15.4) | 10.9 (5.3, 16.6) | 12.8 (5.9, 19.7) | 11.6 (6.8, 16.3) |
| Test of lower bound (p)a | <0.001 | <0.001 | <0.001 | <0.001 |
| Test of upper bound (p)a | <0.001 | <0.001 | <0.001 | <0.001 |
n = 63. MS indicates millisecond; GS, gold-standard. Telemetry operators: CL, TF, TS.
