Anderson-Barker Supplementary Data: Guinea Pig Cardiac Physiology

Anderson-Barker Supplementary Data Files contain original digitized LabChart8 recordings underlying a 2026 Experimental Physiology paper. The dataset includes raw time-series data from guinea pig isolated heart preparations, alongside derived numerical, graphical, and statistical files in GraphPad Prism format. It supports research on cardiac functional assessment, contractility, and QT interval correction methods.

Use Cases

• Validating QT interval correction algorithms using raw ECG time-series data.
• Analyzing cardiac contractility parameters from isolated guinea pig heart recordings.
• Reproducing statistical analyses from the associated paper using the provided GraphPad Prism files.
• Developing methods for processing physiological recordings from LabChart software.

Strengths

• Includes original, unprocessed digitized recordings, providing a foundation for reproducibility.
• Dataset is substantial in size, approximately 540 MB, suggesting detailed raw data.
• Released under a permissive CC-BY-4.0 license, facilitating open reuse.

Limitations

• Column names and row counts are not specified, limiting understanding of data structure.
• Relies on proprietary software (LabChart or LabChart Reader) to access the primary raw data files.
• Metadata is sparse, lacking information on the number of subjects, experimental conditions, or the associated institution.
