reentrant arrhythmia

reentrant arrhythmia

Cardiac pacing An arrhythmia caused by a depolarization that spreads through one part of the heart, and then circles back to depolarize the part of the heart from which it began. See Arrhythmia.

Reddy, "Regional variation of gap junction conductance on reentrant arrhythmia," Biomedical sciences instrumentation, vol.
The AV node conducts the ventricular-paced beat or a premature ventricular contraction (PVC) back (ie, retrograde) to the atrium and depolarizes the atrium before the next atrial-paced beat, the impulse can then trigger the pacemaker to repeatedly pace the ventricle, thereby generating a reentrant arrhythmia circuit known as PMT or endless-loop tachycardia.
Altered conduction and repolarization is the basis of the reentrant arrhythmias thus indicating association of prolonged QT interval with arrhythmogenesis78.
Our results are significant because altered electrical conduction is a mechanism of reentrant arrhythmias (Roden 1996), which can cause tachycardia and fibrillation in both the atria and ventricles.
