Diagnosis Overview

What is Atrial Fibrillation With Rapid Ventricular Rate?
Essential facts and insights about Atrial Fibrillation with Rapid Ventricular Rate

Key Clinical Considerations:

  • Palpitations, shortness of breath, fatigue
  • Electrocardiogram (ECG) showing irregularly irregular rhythm, rapid ventricular response
  • Tachycardia on physical examination, possible signs of heart failure

Clinical Information

Clinical Criteria & Documentation Requirements

  • Patient history including onset and duration of symptoms, previous episodes
  • Use of terms like 'Atrial Fibrillation with Rapid Ventricular Rate' or 'AF with RVR'
  • Examples: 'Patient presents with AF and a ventricular rate of 150 bpm on ECG.'

Coding Guidelines

Usage Guidelines & Examples

  • Follow guidelines for distinguishing between paroxysmal, persistent, and chronic AF.
  • Common errors include misclassifying the type of AF or omitting ventricular rate.

Code Exclusions

Important Exclusions

  • Atrial flutter (I48.3), other specified atrial fibrillation (I48.8)
  • Codes for non-rapid ventricular rate AF
