Atrial fibrillation occurs when action potentials fire very rapidly within the pulmonary veins or atrium in a chaotic manner. The result is a very fast atrial rate — about 400 to 600 beats per ...

Just as in atrial fibrillation, not all of the P waves are able to conduct through the atrioventricular node, and thus the ventricular rate will not be as fast as the atrial rate. Typically ...

ECG plays an important role in detection of several stroke risk factors/predictors including atrial fibrillation and left ... 45–65 years on a 2-min rhythm strip 1.5- to 2.5-fold increase ...
