What is the heart condition associated with an accessory pathway known as the bundle of Kent?

The condition associated with an accessory pathway known as the bundle of Kent is Wolff-Parkinson-White syndrome. This syndrome is characterized by an extra electrical pathway between the atria and the ventricles, which can lead to episodes of rapid heart rate (tachycardia). The bundle of Kent allows impulses to bypass the normal conduction pathway, resulting in a reentrant circuit that can cause the heart to beat more quickly than usual.

In Wolff-Parkinson-White syndrome, the electrocardiogram (ECG) typically shows a shortened PR interval and a delta wave, which is a manifestation of the early activation of the ventricles due to the accessory pathway. Understanding this condition is crucial for paramedics and healthcare providers to manage patients who present with palpitations or arrhythmias effectively.

The other conditions listed do not involve the bundle of Kent and have different pathophysiological mechanisms or causes.
