When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...

Not all atrial flutters demonstrate the typical "sawtooth" pattern. During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of ...

Atrial flutter and atrial fibrillation (AFib) both occur when the electrical signals that make your heart chambers contract occur faster than typical. However, they differ in the organization of ...

With this clearance, vMap’s clinical use now includes non-invasive localization of potential arrhythmia sources associated with atrial flutter mechanisms. This new capability broadens the range of ...

At times it is difficult to distinguish atrial fibrillation from atrial flutter on the ECG. This example shows coarse "fibrillatory waves" in the setting of atrial fibrillation. This are of varying ...

Dr. Hugh Calkins answers the question: 'Atrial Fibrillation vs. Atrial Flutter?' — -- Question: My doctor told me I sometimes have atrial fibrillation and at other times have atrial flutter. What ...
