Atrial Flutter | Reference Guide
EKG Features
Rate: Fast (250-350 bpm) for Atrial, but ventricular rate is often slowerRhythm: Regular or irregular
P Wave: Not observable, but saw-toothed flutter waves are present
PR Interval: Not measurable
QRS: Normal (0.06-0.10 sec)
A series of rapid depolarizations occurring two, three, four or more times per QRS complex.
Atrial flutter is an abnormally fast heart rate where the atria contract rapidly do not adequately pump blood to the ventricles. These fluttering atrial contractions are out of sync with the ventricles. As a result, the heart does not pump blood effectively. Atrial flutter is a common arrhythmia. It is a type of supra-ventricular tachycardia (SVT) and is similar to atrial fibrillation.
