reentrant rhythm

Reentrant rhythm is a pathological heart rhythm disturbance that can lead to serious cardiac events. This occurs when an electrical impulse reenters an area of the heart, creating a circuit that can cause abnormal heartbeats. This mechanism is a significant factor in ventricular arrhythmias, which are a primary cause of sudden cardiac death.1

While premature ventricular contractions can occur in healthy individuals, more dangerous arrhythmias like ventricular tachycardia can compromise circulation and may even lead to ventricular fibrillation, a rhythm incapable of sustaining life. Conditions like Wolff-Parkinson-White syndrome can also cause rapid and life-threatening tachycardias due to alternative conduction pathways. Prompt therapeutic intervention is crucial when ventricular tachycardia or fibrillation is suspected.12
