Key result
Manual expert assessment of ECG intervals shows high inter-investigator variability spanning up to ~99 ms.
Why the study?
ECG time domain parameters are prone to variability, and their expert assessment variability in daily clinical practice needed to be determined.
Is there significant inter-investigator variability in the expert assessment of ECG time domain parameters in daily clinical practice?
Population

Is there significant inter-investigator variability in the expert assessment of ECG time domain parameters in daily clinical practice?
There is high inter-investigator variability in the manual assessment of ECG intervals and wave durations, which could lead to significant variance in ECG-associated diagnoses.
Böck et al. (2023) reported an observational. Manual expert assessment of ECG time domain parameters vs. Computer-aided analysis was evaluated on Variability of clinically relevant ECG wave durations and intervals (interquartile range and Q2/Q98 span). Manual expert assessment of ECG wave durations and intervals demonstrated high inter-investigator variability, with the Q2/Q98 span ranging from 39 to 99 ms.
