In this situation, the ventricular (QRS ... with atrial flutter helps to distinguish it from atrial fibrillation, though atrial flutter with variable conduction of the P waves can also occur.

Medtronic ICDs provide no atrial blanking after sensed ventricular events to ensure reliable sensing of atrial electrograms during atrial fibrillation and flutter. Instead, they reject far-field R ...

Ventricular fibrillation is a cardiac arrhythmia in which the muscle in the lower chambers of the heart (the ventricles) contracts irregularly and rapidly. The ventricles quiver and are unable to ...
