ECG Beat-Level Feature Descriptives by Patient Survival Outcome

Median and interquartile range values for 16 ECG morphology and interval features, derived from 383 beats across 27 patients. The dataset includes Mann-Whitney U p-values for survival outcome comparisons and is corrected for tachycardia (v4.0). It was authored by Alejandro Hernández-Arango and last updated on April 30, 2026.

Use Cases

• Comparing ECG feature distributions between patient survival groups based on reported p-values.
• Developing feature-based models for survival prediction using the 16 morphology and interval features.
• Benchmarking new ECG analysis methods against the provided descriptive statistics for 383 beats.
• Investigating the relationship between tachycardia-corrected ECG intervals and patient outcomes.

Strengths

• Includes statistical test results (Mann-Whitney U p-values) for survival outcome comparisons.
• Contains data from 27 patients, providing a multi-subject basis for analysis.
• Features are derived from 383 individual ECG beats, offering beat-level granularity.
• Dataset is versioned (v4.0) and includes a specific correction for tachycardia.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes beats are not independent, which complicates statistical modeling.
