S1–S8 Videos: 2D Calcium Dynamics in Pacemaker Cell Simulations

Eight videos visualize 2D calcium dynamics under the cell membrane during the final second of 16-second simulations. Each video corresponds to a distinct simulation scenario manipulating parameters for basal or βAR-stimulated states, RyR density, and clustering. Created by Valeria Ventura Subirachs and shared under a CC-BY-4.0 license, this 37.5 MB collection was last updated in May 2026.

Use Cases

• Visualizing calcium wave propagation based on simulated RyR cluster distributions.
• Comparing calcium release patterns between basal and βAR-stimulated cell states.
• Analyzing the functional states of calcium release units (CRUs) based on their color-coded representations.
• Teaching cardiac cell electrophysiology concepts using dynamic simulation outputs.

Strengths

• Videos are precisely defined by eight distinct simulation scenarios with specific parameter values (e.g., Normal Density: 67.65 RyR/μm²).
• Visual encoding is clearly documented, mapping calcium concentrations to red shades and CRU states to specific colors.
• License is permissive (CC-BY-4.0), allowing for broad reuse.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (37.5 MB), which may limit the scope of analysis.
