Population

12 normal subjects

Intervention

Method of directly estimating the alignment error (trigger jitter) from an ECG by relating the variance to the squared slope of the averaged QRS complex, and normalizing amplitude to reduce respiration effects

Outcome

Estimation of alignment errors and proportion of variation attributed to alignment errors and noisesurrogate

A method for estimating ECG alignment errors demonstrates that a significant proportion of QRS variation is due to alignment errors and noise, which can be mitigated by normalizing QRS amplitude.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May confound QRS morphology assessment; leaves open validation of normalization in clinical ECG workflows.
