i. Oxygen, monitor and IV
ii. Ventricular rate > 100 bpm, p waves may appear to be absent, PR interval cannot be measured, rhythm is usually regular, QRS complexes is wide
1. When QRS is wide impulses originate in the ventricles
2. When QRS is narrow impulses originates in the atria
iii. Abnormal EKG, BP is normal or low normal (SBP over 90 mm/Hg), awake, alert, no distress,
iv. Treatment: usually treated medically with Lidocaine or amiodarone
Based on duration, V rate, pt symptoms
If duration <48 hours: Cardioversion: Chemical or mechanical.
If duration >48 hours:
Non-emergent: Anticoagulation for 4-6 weeks, then cardioversion.
In emergencies: IV anticoagulation, transesophageal echocardiogram (TEE) to rule out atrial clots, then cardioversion.
Chronic: Amiodarone, Ca+ Chan Blockers, Beta Blockers
Afib w/ RVR: symptoms- palpitations, SOB, dyspnea, light-headedness, CP, decreased CO
