ZeqHeart — Cardiac Modeling

Biosignals, pharmacokinetics, diagnostics, genomics — all 1.287 Hz pulse-coherent.

• Protocol ID — zeq-heartmodel
• Category — Healthcare
• Endpoint — POST /api/health/heart/model
• Auth — api-key
• Rate limit — 10/min
• Version — 1.0
• Precision — ≤0.1% (KO42-enforced)

What it does

Cardiac electrophysiology modeling using coupled oscillator equations synced to HulyaPulse. Simulates action potential propagation and arrhythmia detection.

Signature

Request

POST /api/health/heart/model

Param	Type	Required	Default	Description
heartRateBpm	number		72	Resting heart rate. Default: 72.
ecgData	array		—	ECG sample data for analysis.
modelType	string		"fhn"	'fhn' (FitzHugh-Nagumo), 'hodgkin-huxley', 'simple'. Default: 'fhn'.

Response

{ actionPotential, rhythmClassification, anomalies, qrsIntervals, pulseSync }

Runnable example

curl -sS -X POST \
  -H "Authorization: Bearer $ZEQ_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "heartRateBpm": 72,
  "ecgData": [],

Integrate

1. Domain solver — compose with KO42 + two additional operators from the matching family for pulse-coherent results.
2. Digital twin — pipe sensor data into this protocol every Zeqond to keep the model phase-locked with the system.
3. Alert threshold — flag results whose error_pct exceeds 0.1% as out-of-spec events for the operations layer.

Seeds

• Near — wrap /api/health/heart/model in a language SDK so builders can call it in three lines.
• Medium — publish a reference integration demonstrating ZeqHeart — Cardiac Modeling alongside a real workload, with pulse-aligned metrics.
• Far — propose ZeqHeart — Cardiac Modeling as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.
