atrial electrical impulse conduction to the ventricles. This is manifested on the
ECG by disassociation of atrial and ventricular rhythms. The atrial rate must be faster
than the ventricular rate. (CDISC);
Alternative definition : NICHD: Complete disassociation of the atrial electrical impulse conduction to the
ventricles.; CTCAE: A disorder characterized by a dysrhythmia with complete failure of atrial electrical
impulse conduction through the AV node to the ventricles.;
