Additional Info

• Includes
  • QT Prolongation Syndrome -- note that this IS included here as an arrythmia, and not as a Cardiac conduction system disorder, NOS
  • Brugada Syndrome
  • POTS postural orthostatic tachycardia syndrome

• Junctional Rhythm
• AV dissociation-the ventricular rate is faster than the atrial rate while in CHB, the ventricular rate is slower than the atrial rate.

Excludes

• Pulseless Electrical Activity (PEA)
• Atrioventricular block, 3rd degree (complete heart block)

Repeated events

If this happens repeatedly during the same ward or unit stay, only code it the first time it happens, regardless of whether it is an Admit Diagnosis or Acquired Diagnosis, rather than each time it happens. See ICD10 codes only coded the first time for other diagnoses coded this way.

Example:

A person has a self-limited episode of A-fib. It goes away and then recurs. Only code the first one. A person has a self-limited episode of A-fib. It goes away but then he has an episode of V-tach. As this is a different diagnosis, both of these should be listed, but only code once each. Patient comes in with hypokalemia. It’s treated and remits, but the next day it recurs. Only code the first time.
