![]() ![]() Afib has less organized activity in the atria and thus provides less uniform “f” waves.Atypical Aflutter may have varying AV conduction, which can cause an irregular heart rhythm. ‘Coarse Afib’ has an “f” wave amplitude> 0.5 mm, which can mimic Aflutter “f” waves morphology. Both of these heart-rhythm disorders arise from electrical misfires in the hearts upper chambers, or atria. ![]() It may be difficult to distinguish atypical Aflutter from coarse Afib. Whats the difference between atrial flutter and atrial fibrillation A. Heart rate ” Irregularly irregular” and variable (slow Afib 100 bpm)įig.2 Atrial fibrillation ECG (with Ashmann phenomenon)ĭistinguish atypical Aflutter from coarse Afib:.Atypical (type II) atrial flutter: doesn’t fulfill the criteria for typical atrial flutter.Clockwise: positive flutter waves in II, III, aVF and negative in V1.Counterclockwise: negative flutter waves in II, III, aVF and positive in V1.You and your doctor will decide which one is right for you. Typical (type I) atrial flutter: saw-tooth-like waves Treatment Heart & Vascular Atrial Flutter Treatments Depending on the type and severity of your arrhythmia, and the results of various tests including the electrophysiology study, there are several treatment options.300 bpm (200-400 bpm) with a heart rate typically ca. Afib and atypical Aflutter requires more expertise and radiofrequency ablation has lower success rate.Ītrial rate ca. The difference between atrial fibrillation (Afib) and atrial flutter (Aflutter), is clinically relevant because typical flutter can easily be treated by radiofrequency ablation. ![]()
