Key result
Equation correction for ECG-based AFib detection does not alter original study conclusions.
This is a correction notice fixing a typographical error in an equation from a previously published paper on atrial fibrillation detection.
Answers are grounded in this paper and cite their sources.
Correction preserves original AF detection conclusions; leaves open prospective validation for clinical use.

Anbalagan et al. (2026) studied Atrial Fibrillation. ECG Signal Feature Selection and Classification was evaluated. A typographical error in Equation 5 of the original article regarding the detection of atrial fibrillation from ECG signals was corrected without impacting the study's results or conclusions.
