Atrial fibrillation with rapid ventricular response

Definition

Atrial fibrillation with rapid ventricular response (AFib with RVR) is a condition where the atria beat irregularly and frequently, leading to a fast heart rate in the ventricles. This can result in poor blood flow and increased risk of stroke.

5 Must Know Facts For Your Next Test

1. A common symptom of AFib with RVR is palpitations, along with dizziness and shortness of breath.
2. Rate control is crucial in managing AFib with RVR, often using beta-blockers or calcium channel blockers.
3. Anticoagulants may be prescribed to reduce the risk of stroke associated with AFib.
4. Electrical cardioversion can be used to restore normal heart rhythm if medications are ineffective.
5. AFib with RVR can lead to hemodynamic instability, requiring immediate medical intervention.
