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.
How to Record
1. Open the ECG app on Apple Watch and rest for 30 s.
• Need extra precision? High‑Precision Mode lets you record back‑to‑back sessions.
2. Tap Extract Latest ECG Data in Heart Rate Fragmentation app to see results.
3. Short‑term (7‑30 days), persistent (31‑60 days) and chronic (61-90 days) trends are tracked automatically.
