  <description
               value="Local codes for cardiac monitoring metrics that have no equivalent in LOINC
or SNOMED CT. The set is deliberately small: each Tiro code documents a
genuine terminology gap (AFib burden / episode statistics, sinus pause
counts and longest pause, ventricular- and supraventricular-tachycardia
run counts and longest runs, and per-panel Holter grouper codes that
LOINC does not currently provide).

Codes covered by LOINC or SNOMED CT are NOT duplicated here — see the
example instances for the chosen LOINC/SCT codes (PVC count `LOINC#76126-2`,
premature atrial contractions `LOINC#8615-7`, atrial fibrillation
`SCT#49436004`, …).

These codes are a stopgap. Each entry should be replaced with a LOINC or
SNOMED CT code as soon as a suitable concept becomes available."/>
