AFib Origin and Prevalence
- Atrial fibrillation (AFib) is a common arrhythmia, increasing with aging populations.\n- It results from rapid, disorganized electrical firing near pulmonary veins in the left atrium.
Emergency AFib Cardioversion
- If a patient with AFib is hemodynamically unstable, perform synchronized urgent cardioversion promptly.\n- Provide sedation or analgesics before shock to reduce patient discomfort.
AFib Rate vs Rhythm Control
- For stable AFib, decide on rate control versus rhythm control based on symptoms and side effects.\n- Avoid over-aggressive rate control; target heart rate under 110 bpm usually suffices.
