  "description" : "Local codes for cardiac monitoring metrics that have no equivalent in LOINC\nor SNOMED CT. The set is deliberately small: each Tiro code documents a\ngenuine terminology gap (AFib burden / episode statistics, sinus pause\ncounts and longest pause, ventricular- and supraventricular-tachycardia\nrun counts and longest runs, and per-panel Holter grouper codes that\nLOINC does not currently provide).\n\nCodes covered by LOINC or SNOMED CT are NOT duplicated here — see the\nexample instances for the chosen LOINC/SCT codes (PVC count `LOINC#76126-2`,\npremature atrial contractions `LOINC#8615-7`, atrial fibrillation\n`SCT#49436004`, …).\n\nThese codes are a stopgap. Each entry should be replaced with a LOINC or\nSNOMED CT code as soon as a suitable concept becomes available.",
