Heart + ECG: Create a Sleep or Workout Report

Purpose

Use APOPT Heart Analysis with a Polar H10 or another supported single-lead ECG source. Record an authorized sleep/rest or workout session, evaluate signal quality, and create a careful coaching report.

What the tool does

The browser-based platform conditions the signal, detects R peaks, verifies candidate rhythm events against the recording’s typical beat shape, and reports coverage before interpretation. Depending on session type, outputs may include heart-rate trends, time- and frequency-domain HRV, estimated breathing rate, Poincaré measures, sleep/rest proxies, interval detection, heart-rate zones, TRIMP, post-peak recovery, recovery time constant, and prioritized rhythm-screening candidates.

Two anonymized example reports demonstrate the coaching value of quality checks. A high-quality overnight/rest recording showed a low stable heart-rate profile, strong beat-to-beat variability, hourly change, and an HR/HRV-based sleep-stage proxy. The report clearly stated that ECG alone cannot confirm sleep stages. A high-quality interval workout showed five repeatable effort blocks, a peak near 180 bpm, and a 24-bpm drop in the first minute after the detected peak. Artifact screening rejected a distorted candidate so it did not contaminate the rhythm summary.

These are descriptive signals, not diagnoses. A single recording does not establish an athlete baseline.

Deriving actionable insight

Follow this order:

1. Recording context: sleep/rest or workout, duration, symptoms, protocol, and device fit.

2. Usability: HR, HRV, morphology coverage, gaps, contact shifts, and detector agreement.

3. Session pattern: stable overnight trend or repeatable workout peaks and recoveries.

4. Within-athlete comparison: compare only with similar sessions collected under similar conditions.

5. Coaching action: adjust routine, repeat the recording, or ask a qualified professional—not diagnose.

90–120 minute assignment

0–15 minutes — Plan and consent. Choose your own data or obtain athlete authorization. Select sleep/rest or a workout. Record the question, protocol, symptoms if volunteered, and expected duration.

15–55 minutes — Record. Fit the Polar H10 correctly and collect the session. For a workout, use a repeatable protocol such as warm-up, 4–6 controlled efforts, recoveries, and cool-down. Stop for concerning symptoms and follow normal safety procedures.

55–75 minutes — Run the analysis. Review coverage before interpreting HR or HRV. Inspect any low-quality period and at least one waveform window.

75–100 minutes — Write the report. Include context, quality, three descriptive findings, one limitation, one coaching question, and a recommended reassessment. If the output flags a rhythm candidate, describe it only as a screening item requiring appropriate review.

100–120 minutes — Compare and explain. Compare the report with the athlete’s experience. Write a 100-word athlete-facing explanation.

Questions to answer

1. What can this recording validly support?

2. Which output is most sensitive to artifact or context?

3. What pattern is descriptive rather than diagnostic?

4. What should be repeated under similar conditions?

5. What finding, symptom, or uncertainty belongs outside coaching scope?

Generative AI knowledge check

Prompt 1: “Review this de-identified Heart Diagnostics report as a coaching-data quality auditor. Separate recording-quality facts, descriptive physiology, screening candidates, limitations, and appropriate next steps. Do not diagnose.”

Prompt 2: “Explain the difference among resting heart rate, RMSSD, SDNN, pNN50, estimated breathing rate, post-exercise HR recovery, TRIMP, and rhythm screening. For each, give one coaching use and one reason it can mislead.”

Prompt 3: “Create five scenario questions that test whether I can distinguish sensor artifact, a repeatable training/recovery pattern, and a situation that requires qualified medical review. Grade my answers conservatively.”

Submit a de-identified PDF or summary, the quality-first interpretation, the athlete-facing explanation, and the reassessment plan. Never use the tool for diagnosis, clearance, or treatment decisions.
