This is commonly described as varying RR intervals. This means an ECG showing atrial fibrillation will have no visible P waves and an irregularly irregular QRS complex. The ventricular rate is ...

With atrial fibrillation, no descrete P waves can be seen, however sometimes coarse "fibrillitory waves" are present. In atrial flutter a "sawtooth" pattern is seen. In MAT there are at least 3 ...

Yang et al. propose a new approach to identify features associated with the risk of atrial fibrillation (AF) using standard 12-lead raw electrocardiogram (ECG) tracing. The features identified in ...

Background: Several clinical factors have been studied to predict atrial fibrillation (AF ... is extracted from surface electrocardiographic (ECG) recordings. The AA will be characterized through ...
