Echocardiographic Myocardial Performance Index (MPI / Tei Index) Skill

A zero-dependency, mathematically rigorous personal agent skill that computes the Doppler Tei Index (Myocardial Performance Index) to evaluate combined ventricular systolic and diastolic function.

Quick Start

from client import MyocardialPerformanceTeiIndexClient

client = MyocardialPerformanceTeiIndexClient()
result = client.evaluate_tei_index(
    interval_a_ms=385.0,
    ejection_time_et_ms=295.0,
    isovolumetric_relaxation_time_ivrt_ms=50.0
)
print("Tei Index (MPI):", result["tei_metrics"]["myocardial_performance_index_mpi"])
print("Status:", result["cardiac_assessment"]["clinical_status"])
