Oct 23, 2001 · A rapid, irregular, sustained, wide-QRS-complex tachycardia strongly suggests AF with conduction over an accessory pathway or AF with underlying bundle-branch block. Extremely rapid rates (over 200 bpm) suggest the presence of an accessory pathway. B. Related Arrhythmias.
Jan 6, 2023 · Atrial fibrillation with rapid ventricular rate (A-fib with RVR) is a type of irregular heart rhythm. With A-fib with RVR, your heart doesn’t have a normal signaling process telling your heart when to beat. Instead, signaling is disorganized and the parts of your heart beat out of sync.
Apr 4, 2017 · The association of an irregular pulse and mitral stenosis was first described by Robert Adams in 1827, but it was not until the turn of the 20 th century when William Einthoven invented electrocardiography that atrial fibrillation (AF) was first recorded on the electrocardiogram. 1 Its pathogenesis and clinical importance gained enhanced appreci...

Rapid ventricular response ( RVR ): a ventricular rate > 100–110/minute occurring in response to a. supraventricular tachyarrhythmia. [2] [3] [4] RVR is often but not always associated with.
Atrial fibrillation with rapid ventricular response (RVR) is common during critical illness. In this study, we explore the comparative effectiveness of three commonly used drugs (metoprolol, diltiazem, and amiodarone) in the management of atrial fibrillation with RVR in the intensive care unit (ICU). Methods.
Antiarrhythmic medications have been available for nearly 100 years and remain a mainstay in the management of atrial fibrillation (AF). Goals of therapy with the use of these drugs include a reduction in the frequency and duration of episodes of arrhythmia as well an emerging goal of reducing mortality and hospitalizations associated with AF.
Atrial fibrillation is the most common sustained arrhythmia, increases with age, and presents with a wide spectrum of symptoms and severity. Paroxysmal, persistent, and permanent forms require very individualized approaches to management.
Clinicians should be mindful of the idiosyncrasies of vagal AF in terms of diagnosis, triggers and medical therapies. Although there is no consensus regarding the benefits of treating vagal AF, early ablation and/or early rhythm control may prevent degeneration into persistent or even permanent AF.
Dec 16, 2020 · It is defined as atrial fibrillation with a ventricular rate over 100bpm. However the RACE II trial showed that more lenient rate control of a HR under 110 was non-inferior to more strict control of HR under 80. So in general when treating afib in the ED aim for an HR of 110 or less [5].
