Bermejo Valdés, Alejandro Jesús 3D ECG dataset for QRS notch analysis in left bundle branch block Mendeley Data This dataset contains high-definition two-dimensional (2D) and three-dimensional (3D) electrocardiographic (ECG) figures from patients with left bundle branch block (LBBB) and from randomly selected normal control recordings, specifically curated for the analysis of QRS notching patterns. The dataset includes 2D ECG representations of six standard leads (I, aVL, V1, V2, V5, and V6) and corresponding 3D ECG spatial representations that enable the identification and characterization of notches not always apparent in conventional 2D ECG analysis. All figures were generated using standardized preprocessing and visual assessment criteria, with color-coded temporal segmentation of the QRS complex based on predefined marker points. The dataset is intended to support reproducibility, methodological development, and comparative studies focused on notch detection and spatial QRS morphology in cardiovascular electrophysiology. 3D Analysis Cardiac Electrophysiology Electrocardiography Left Bundle Branch Block ECG Leads Dataset doi:10.17632/62pgxgx4sb.1 oai:data.mendeley.com/62pgxgx4sb.1 Attribution-NonCommercial 3.0 Unported https://creativecommons.org/licenses/by-nc/3.0 https://data.mendeley.com/datasets/62pgxgx4sb 2026-01-22T10:32:53Z
