Make your HRV assessments
mean something.
A practitioner tool that turns emWave® Pro Plus assessment data into plain-language interpretation — for you and your clients.
This walkthrough shows the HRV Interpreter as a standalone app. The tool is now part of the combined HeartMath Practitioner Workspace at coherence-tools.heartmathsouthafrica.co.za — the functionality shown is identical.
The emWave® Pro Plus gives you numbers.
This gives you the conversation.
- My client’s SDNN is 28ms. What do I tell them?
- The coherence score looks low. Is that from stress, or from poor practice quality?
- Their LF/HF ratio is elevated. Should I mention that — and if so, how?
- How do I present a 5-minute assessment to a corporate client in plain language?
- We’ve been working together for eight weeks. How do I show progress?
Everything the raw numbers
don’t say out loud.
Import directly from emWave® Pro Plus PDF assessments. No data entry. No guesswork. A complete interpretive report — client-ready in under a minute.
Drag and drop your assessment PDF
Drop a 1-minute or 5-minute emWave® Pro Plus assessment PDF and all fields populate automatically — values, reference ranges, and assessment date.
Plain-language interpretation, ready to share
Each metric generates a contextualised explanation that a client can read and understand — no clinical vocabulary, no alarm. Awareness and action, not diagnosis.
Practitioner notes and clinical context
A parallel professional view gives you the full picture — including burnout indicators, capacity-not-expressed patterns, and elevated RMSSD context.
SDNN, RMSSD, MHRR, Coherence, Heart Rate, IBI
Age-adjusted reference ranges for all 1-minute metrics. Interpretation accounts for the interaction between metrics, not just individual values.
Full spectral breakdown — VLF, LF, HF, LF/HF, Total Power
All five-minute frequency domain metrics interpreted in context. Coherence formula cited to McCraty et al. 2006 The Coherent Heart.
Baseline vs current — side by side
Drop a baseline and a current assessment, generate a directional progress narrative. Show clients what eight weeks of practice actually looks like in their data.
HRV Interpreter and CSI — one workspace
Both tools live at a single URL. Switch between HRV assessment reports and coherence session interpretations without logging in twice — and print combined reports that bring both data streams together in one document.
The HRV Interpreter works alongside the Coherence Session Interpreter (CSI) → — a longitudinal companion that tracks progress across every coherence training session.
What the report
actually looks like.
Below is a representative view of the practitioner screen — showing metric cards, status classification, and generated interpretation text.
1-Minute HRV Assessment
Assessed: 18 June 2026 · Practitioner: [Your name]Your overall heart rhythm variability is within the expected range for your age group, which tells us your nervous system has capacity available. The lower coherence reading suggests that capacity isn’t currently being expressed as a rhythmic, ordered pattern — something that responds directly to focused heart-rhythm practice. This is a common starting point, and it’s a useful baseline to return to after six to eight weeks of regular practice.
Illustrative only. Actual output generates from imported PDF data.
“The reading is a starting point for a conversation — not a verdict. The interpreter gives you the language to open that conversation with every client, every time.”
