Overview
Atrial flutter should be differentiated from atrial fibrillation, multifocal atrial tachycardia, SVT and wide complex tachycardia. An electrocardiogram artifact from tremor also can be confused with atrial flutter.
Differentiating Atrial Flutter from other Diseases
Atrial flutter should be differentiated from the following rhythm disorders:
- Atrial fibrillation - ECG shows irregularly irregular rhythm with uncoordinated atrial activation, absent P waves, atrial rate of 400-700 beats per minute and with rapidly oscillating, fibrillatory waves that vary in amplitude, shape, and timing.
- Multifocal atrial tachycardia - organized and discrete P waves with at least 3 different morphologies is the distinguishing character with variable PP intervals, RR intervals, and PR intervals.
- Supraventricular tachycardia - is a tachycardia or rapid rhythm of the heart in which the origin of the electrical signal is either the atria or the AV node. In general, QRS complexes tend to be tall and narrow, P waves are absent, and rate is greater than 100 beats per minute.
- Wide complex tachycardia - cardiac rhythm of more than 100 beats per minute with a QRS duration of 120 milliseconds or more
- Atrial tachycardia with AV block.
