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 ...

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 ...

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 ...
