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 normal. However, they differ in how this electrical ...

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 ...

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 ...

If you are a nurse, doctor or other medical professional that deals with cardiac issues or ECG readings, you owe it to yourself and your patients to take an EKG interpretation course. An EKG ...
