Short answer

How do I calculate HRV metrics with my AI?

Paste your R-R interval data into the chat. Your agent uses specialized tools to calculate SDNN and RMSSD values immediately. You'll get the specific physiological metrics you need.

The outcomes of your data processing.

Where your metrics land.

Your AI transforms raw timestamps into specific physiological values.

METRICS

SDNN values

The AI calculates the standard deviation of NN intervals. You get a clear view of your overall autonomic activity.

METRICS

RMSSD values

The agent finds the root mean square of successive differences. This shows your parasympathetic nervous system activity.

ANALYSIS

Trend data

Your agent can compare these calculated values over time. You'll see how your recovery shifts between sessions.

HUMAN

Your interpretation

The AI provides the math, but you decide what the numbers mean for your health. It doesn't provide medical advice.

The workflow

What your AI does when the data arrives.

The AI handles the heavy lifting of the math once you provide the data.

  1. Data ingestion

    Your agent reads the raw R-R interval list you provide in the chat.

  2. SDNN calculation

    The AI runs the standard deviation math on your interval sequence.

    calculate_sdnn

  3. RMSSD calculation

    The agent calculates the successive differences to find the RMSSD value.

  4. Result delivery

    The AI presents the final SDNN and RMSSD numbers in your chat window.

FAQ

How the calculator behaves

  • 01

    Can the AI calculate HRV from heart rate (BPM) alone?

    No. The tools require R-R interval data to perform the math.

  • 02

    Will the AI pull data from my wearable automatically?

    No. You must provide the R-R interval data to the AI client yourself.

  • 03

    Can the AI tell me if my HRV is healthy?

    No. The AI only calculates the numbers. You must interpret them yourself.

  • 04

    Does the AI store my physiological data?

    No. The AI processes the data you provide in the session, but it doesn't save it.

  • 05

    What specific metrics can I get?

    You can get SDNN and RMSSD values.
