Implication

Clinicians should verify automated ECG intervals; leaves open the need for standardized algorithms and expert validation.

Key Points

The research aims to evaluate the performance and accuracy of various ECG computer programs using a standardized reference database.
Established a reference library with 250 ECGs featuring selected abnormalities.
Reviewed ECG wave onsets and offsets by cardiologists using a modified Delphi approach.
Analyzed results from nine vectorcardiographic and ten standard 12-lead ECG analysis programs against referee estimates.
Median measurements from programs were close to referee estimates, with QRS variations reaching 10 msec for some.
Variances among programs differed significantly in relation to referee estimates.
Certain programs performed better on high-noise vs low-noise recordings, affecting accuracy.

How do different ECG computer programs compare to expert visual determination in measuring ECG wave onsets and offsets?

Population

An ECG reference library of 250 ECGs with selected abnormalities

Intervention

9 vectorcardiographic and 10 standard 12-lead ECG analysis programs

Comparator

Visual determination of the onsets and offsets of P, QRS, and T waves by a group of cardiologists (referee estimates)

Outcome

Accuracy and variability of P, QRS, and T wave onsets and offsets compared to referee estimatessurrogate

Significant variability exists between different ECG computer programs in measuring wave onsets and offsets, highlighting an urgent need for standardization.
