- A cardiac rhythm characterized by independent atrial and ventricular complexes with the atrial rate exceeding ventricular rate and complete failure of atrial impulses to conduct to the ventricle.
- A disorder affecting the conduction system that sends electrical signals in the myocardium.
- A disorder characterized by a dysrhythmia with complete failure of atrial electrical impulse conduction through the av node to the ventricles.
- A disorder characterized by pathological irregularities in the cardiac conduction system.
- Abnormality in rhythm of heartbeat, including rate, regularity, and/or sequence of activation abnormalities
- Complete failure of atrial electrical impulse conduction through the av node to the ventricles.
