Long-term ECG Recordings and Signal Quality Data

This dataset contains electrocardiogram (ECG) recordings and derived signal-quality data collected during a study comparing textile-based Texatrode® electrodes with conventional pre-gelled Ag/AgCl electrodes for long-term ECG monitoring. The dataset contains recordings from 13 participants undergoing follow-up after pulmonary vein ablation for atrial fibrillation. ECG data were recorded continuously for up to 7 days using a three-lead configuration. Each participant was simultaneously monitored using one textile-based electrode lead and two conventional gel electrode leads. The dataset includes: * ECG recordings in European Data Format ('.edf')* R-peak detection and ECG quality data ('HRV.csv')* Overall ECG quality statistics ('PERF.csv')* Segment-level ECG quality data ('Q.csv') The data are provided to support reproducibility and further methodological research on long-term ECG monitoring, ECG signal quality assessment, and textile-based electrodes.
