What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Atrial stimulation threshold. It is commonly used with the system or sample type Pacemaker.permanent.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Observation

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

Permanent pacemaker Atrial stimulation threshold
Atrial stimulation threshold
This term represents the atrial stimulation threshold for permanent (implanted) pacemakers. Temporary pacemaker atrial stimulation threshold is measured in mA rather than mV and should be recorded using [LOINC99680-1].
