Background Cavotricuspid isthmus-dependent counterclockwise atrial flutter (typical AFL) is characterized by negative saw-tooth morphology flutter wave (F-wave) in the inferior leads, which is classified as type 1 with purely negative F-wave without positive terminal deflection (PTD), type 2 with ...
The purpose of this study was to characterize variations in flutter-wave (F-wave) morphology among patients with clockwise isthmus-dependent (CWID) and counterclockwise isthmus-dependent (CCWID) right atrial flutter (AFL) and to attempt to correlate F-wave morphology with echocardiographic data and ...
In case of atrial flutter, the subsequent F wave intervals will “map out” perfectly. In AF, the shape and polarity of f waves often vary over the length of the tracing. Even if the shape of f waves appears similar, their timing will be “off” (Fig. 15.12). • The propagation ...
Separating atrial flutter from atrial fibrillation with apparent electrocardiographic organization using dominant and narrow F-wave spectra. The purpose of this study was to separate atrial flutter (AFL) with atypical F waves from fibrillation (AF) with "apparent organization." We hypothesized t... BL...

Key difference: Flutter is a regular rhythm whereas fibrillation is irregular. Paroxysmal supraventricular tachycardia : a type of supraventricular tachycardia characterized by narrow QRS complexes and a fast heart rhythm, typically between 150 and 240 beats per minute Multifocal atrial tachycardia : a ...

Entrainment pace mapping from this area produced an exact P wave match to atrial flutter on 12-lead ECG with a long (greater than 40 msec) stimulus-to-P interval indicating slow conduction, whereas pacing just inferior or posterior to the coronary sinus ostium produced an exact P wave match ...
