Pathology - Wolff-Parkinson-White Syndrome
Pathophysiology Pre-excitation supraventricular tachycardia, as this disorder is known, is brought on by an aberrant auxiliary conduction route that connects the ventricles and atria. This channel (Kent accessory bundle) is where electrical signals can flow and produce PVC. The most typical signs and symptoms of this illness include syncope or near-syncope, dizziness, lightheadedness, and paroxysmal episodes of palpitations. A "delta" wave on the ECG, which manifests as an upward "slurring" of the QRS complex, is used to make the diagnosis. A brief PR interval is also visible on the ECG. These two results actually show that the ventricle is excited prematurely by an abnormal atrial impulse that lacks normal AV nodal regulation. Under this circumstance, sudden death is uncommon. The ailment is frequently observed in youth, and its definitive treatment is ablation of the auxiliary route.
