Atrial fibrillation can be interpreted by noting.
When you have atrial fibrillation, the electrical system that powers your heart and keeps its rhythm regular doesn't work correctly. Instead of steady, regular impulses triggering each heartbeat, numerous impulses are generated in a rapid and disorganized manner, causing the upper chambers of the heart (atria) to beat erratically and out of sync with the lower chambers (ventricles).
Atrial fibrillation: Can electrograms be interpreted without repolarization information?“The use of adenosine can improve mapping where atrial fibrillation drivers are not easily identifiable and allow us to more accurately find the exact source of these drivers and ablate.” Dr. Hummel, who led the clinical portion of the research, notes that 80% of the patients who had persistent atrial fibrillation were helped by this safer ... In atrial fibrillation or atrial flutter, the atria do not empty completely into the ventricles with each beat. Over time, some blood inside the atria may stagnate, and blood clots may form. Pieces of the clot may break off, often shortly after atrial fibrillation converts back to normal rhythm—whether spontaneously or because of treatment. In atrial fibrillation or atrial flutter, the atria do not empty completely into the ventricles with each beat. Over time, some blood inside the atria may stagnate, and blood clots may form. Pieces of the clot may break off, often shortly after atrial fibrillation converts back to normal rhythm—whether spontaneously or because of treatment.

Atrial rhythms originate in the atria rather than in the SA node. The P wave is positive, but its shape can be different from a normal sinus rhythm because the electrical impulse follows a different path to the AV (atrioventricular) node. Common atrial arrhythmias include premature atrial contractions, atrial fibrillation, and atrial flutter.
Diagnosis. Treatment. Complications. Atrial fibrillation is a heart condition that causes an irregular and often abnormally fast heart rate. A normal heart rate should be regular and between 60 and 100 beats a minute when you're resting. You can measure your heart rate by checking your pulse in your wrist or neck.
