Comparing AFib and AFib with RVR. Though atrial fibrillation and AFib with RVR share the same irregular heartbeat, they are distinct in their manifestations. While atrial fibrillation is marked by the atria quivering or fibrillating, atrial fibrillation with rapid ventricular response is a subtype of this condition which signifies a rapid heart
Stable atrial fibrillation with rapid ventricular response (stable Afib with RVR): If persistent, give amiodarone IV bolus 150mg and start amiodarone drip 1mg/
frequently progresses to Afib. For the management of atrial fibrillation with a ventricular rate 100–110/minute, see . Afib with RVR .
The following focuses on acute management of Afib with RVR and atrial flutter with RVR. Rate control vs. rhythm control. Onset ≥ 48
Some cases of Afib involve atrial fibrillation with rapid ventricular response (RVR). amiodarone; dofetilide; dronedarone; flecainide; propafenone
AFib with RVR: Diagnosis Management ⤵️ Dx: HR is irregular Do not use digoxin, nondihydropyridine CCB, and amiodarone in those with Afib
If resolves, start PO of metoprolol or diltiazem, whichever broke the Afib RVR. Goal HR 110. If persistent, give amiodarone IV bolus 150mg and start amiodarone drip 1mg/min. Unstable atrial fibrillation with rapid ventricular response (unstable Afib with RVR): proceed directly to synched cardioversion; Chest Pain/Acute Coronary Syndrome
▫ Amiodarone. ▫ Sotalol. ▫ Flecainide/Propafenone. ▫ Dronedarone ▫ Usually AFIB with RVR reflects enhanced sympathetic tone from underlying.
Amiodarone can be used for both rate and rhythm control in AF. That is, it may slow the rate and/or convert afib to NSR. To slow afib with RVR

Keep them coming 😊
BTW. Standalone CHF taking down an otherwise healty person like that??? No afib, no obesity, no alcoholism, no bundle blockage or left side failure??
