Description
Is your heart rhythm getting choppy? Heart Rate Fragmentation turns a 30‑second Apple Watch ECG into an early‑warning Stress & Recovery Score—an ECG‑based stress check you can run every morning. All findings are backed by published studies (referenced inside the app).
Why Heart Rate Fragmentation > Heart Rate Variability? • Heart Rate Variability is skewed by – movement, breathing, and extra or missed heart beats. • Heart Rate Fragmentation can identify micro‑transitions to reveal true heart rhythm smoothness and information on how effective your heart rate adapts even when the trace looks normal.
Key Metrics • PIP (Percentage Inflection Points) – overall smoothness. • Heart rate patterns: Waves (Smooth, Moderate, and Choppy) and turn transitions (gentle and hard) show how your heartbeat adjusts moment‑to‑moment. • VFI (Vagal Fragmentation Index) – ‘rest and digest’ strength. Based on emerging peer‑reviewed research; not yet a clinical standard.
