R-DECO

R-DECO detects and corrects R-peaks in electrocardiogram (ECG) signals to enable accurate derivation of RR-intervals and heart rate variability metrics.

Key Features:

• Envelope-Based Detection Algorithm: An envelope-based detection procedure flattens the ECG signal and enhances QRS-complexes for R-peak identification.
• Detection Performance: Validated on the MIT/BIH arrhythmia database with reported sensitivity of 99.60% and positive predictive value of 99.69%.
• Matlab Implementation: Implemented in Matlab as stated in the original description.
• Support for Multiple Data Formats: Accepts various input data formats for ECG signals.
• Integrated Filtering Options: Includes three basic filters for ECG signal preprocessing.
• Correction of Anomalies: Provides routines to correct ectopic, wrong, or missed heartbeats in RR-interval series.
• Export Functionality: Exports analysis results in Matlab and Excel formats.

Scientific Applications:

• Heart Rate Variability Analysis: Produces accurate RR-interval series required for deriving heart rate variability metrics.
• Arrhythmia Detection and Classification: Enhances visibility and correct identification of QRS-complexes to support arrhythmic event analysis.
• Clinical Research: Improves data integrity for studies involving ECG analysis and cardiovascular investigations.
