Dual-Sensor Pulse Arrival Time (PAT / PTT) Skill

Zero-dependency sovereign personal agent skill for non-invasive evaluation of dual-sensor Pulse Arrival Time (PAT), Pulse Transit Time (PTT), pulse wave velocity (PWV), and arterial elasticity.

Features

• Deterministic Math: Pure Python standard library implementation with zero external dependencies.
• Hemodynamic Moens-Korteweg Principles: Implements validated equations linking pulse wave transit to arterial wall stiffness.
• Continuous Cuffless Cardiovascular Monitoring: Enables continuous beat-to-beat vascular tone assessment.
• Model Context Protocol (MCP): Native JSON-RPC tool integration for LLMs and autonomous agents.

Quickstart

from client import PulseArrivalTimeClient

client = PulseArrivalTimeClient()
result = client.evaluate_pulse_transit(
    pat_ms=215.0,
    pre_ejection_period_ms=85.0,
    arterial_path_length_m=0.82
)
print("Pulse Wave Velocity:", result["pulse_wave_velocity_pwv_m_s"], "m/s")
print("Classification:", result["classification"])
