Heart Rate Fragmentation is a powerful, research-grade application designed for cardiovascular researchers, clinicians, and healthcare professionals who need to analyze heart rate variability using advanced Heart Rate Fragmentation (HRF) metrics. Simply format your RR intervals input file(s) according to the instructions and then choose where to save the results.
Key Features:
-Advanced HRF Analysis
Calculate standard HRF metrics: PIP (Percentage of Inflection Points), IALS (Inverse Average Length of Segments), PSS (Percentage of Short Segments), and PAS (Percentage of Alternating Segments)
Generate symbolic HRF metrics using configurable thresholds
Compute symbolic word metrics (W0, W1H, W1S, W2H, W2S, W2M, W3H, W3S, W3M) for comprehensive analysis
-Batch Processing
Process multiple CSV files simultaneously
Support for multiple participants or time windows in a single file
Automatic file organization and result compilation
-User-Friendly Interface
Intuitive onboarding tutorial for first-time users
Step-by-step guidance through the analysis process
