Type I atrial flutter, also known as common atrial flutter or typical atrial flutter, has an atrial rate of 240 to 340 beats/minute . However, this rate may be slowed by antiarrhythmic agents.
Read moreIs anticoagulation needed for atrial flutter?
Most patients with atrial flutter should be considered for chronic anticoagulation in a manner similar to those with atrial fibrillation (AF). This recommendation is based not only on the fact atrial flutter carries a risk for systemic embolization but also that these patients usually have episodes of AF.
Read moreHow long does cardioversion last for atrial flutter?
Pharmacological cardioversion mainly converts recent-onset AF of <48 h duration.26 Nis 2020
Read moreWhat medications cause atrial flutter?
New-onset AF has been associated with cardiovascular drugs such as adenosine, dobutamine, and milrinone . In addition, medications such as corticosteroids, ondansetron, and antineoplastic agents such as paclitaxel, mitoxantrone, and anthracyclines have been reported to induce AF.
Read moreWhat drugs contraindicated atrial flutter?
Beta-blockers, non-dihydropyridine calcium channel blockers, digoxin, and intravenous amiodarone are contraindicated in these patients; flecainide or amiodarone can be used instead.
Read moreWhat is a Fibrillatory wave?
Fibrillatory waves (Fw) are found of the surface 12‐lead electrocardiograms (ECGs) of patients in AF (Figure 1). They are oscillations in amplitude around the baseline and are dependent on the magnitude of the underlying voltage .
Read moreDoes atrial flutter have a QT interval?
In conclusion, a short QT interval can be readily identified based on the first percentile of the new QTc formula. A short QTc is an important marker for the development of atrial arrhythmias, including atrial flutter and atrial fibrillation, with the former predominating.
