Seizure ECG Data: Electrocardiograms During Convulsive Seizures

ECG recordings captured during convulsive epileptic seizures, including Generalized Tonic-Clonic Seizures (GTCS) and Focal-to-Bilateral Tonic-Clonic Seizures (FTBTC). The dataset is 297.1 MB in size and was published by Philippa Karoly, with a last update in June 2026. It is associated with a 2025 study in the Journal of Neural Engineering on seizure detection using heart rate variability.

Use Cases

• Training seizure detection models based on ECG-derived heart rate variability.
• Analyzing cardiac patterns during Generalized Tonic-Clonic Seizures (GTCS).
• Comparing ECG signatures between focal-onset and generalized convulsive seizures.
• Developing pseudoprospective validation frameworks for ambulatory monitoring systems.

Strengths

• Dataset size is 297.1 MB, indicating a medium-scale collection of physiological recordings.
• Specifically focuses on ECG during convulsive seizures (GTCS and FTBTC), a clinically relevant subset.
• Associated with a peer-reviewed publication (Journal of Neural Engineering, 2025), suggesting research validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Description metadata is limited; actual data quality and recording parameters require manual inspection.
