<prompt> Which of the following statements is true about the bundle of kentIt is slower than the AV nodal pathwayIt is muscular or nodal pathway between the atria and ventricle in WPW syndromeAbnormal pathway between two atriadirect conduction to av node  <response>: In the normal hea, atrioventricular conduction occurs across the specialized axis comprising the atrioventricular node with its zones of transitional cells, the bundle of His, and the ventricular conduction pathways. This axis, for conduction to be normal, must be the solitary muscular connection between the atria and the ventricles. Accessory pathways APs occur in 1 in 1500- 2000 people and are associated with a variety of arrhythmias including narrow-complex PSVT, wide- complex tachycardias, and, rarely, sudden death. Most patients have structurally normal heas, but APs are associated with Ebsteins anomaly of the tricuspid valve and forms of hyperophic cardiomyopathy including PRKAG2 mutations, Danons disease, and Fabrys disease. WPW syndrome - accessory connections between aium and ventricle. This bypass tract may be atriofascicular, fascicular, intranodal, or nodoventricular mc is the atrioventricular pathway or Bundle of Kent. Conduction through this bundle can be either anterograde, retrograde, or both. Accessory pathways capable of only retrograde conduction - called as concealed Accessory pathways capable of anterograde conduction - called as manifest If the impulse from the sinus node conducts through the AP to the ventricle antegrade before the impulse conducts through the AV node and His bundle, then the ventricles are preexcited during sinus rhythm, and the ECG shows:- A sho P-R interval 0.12 s, Slurred initial poion of the QRS delta wave, and Prolonged QRS duration produced by slow conduction through direct activation of ventricular myocardium over the AP Ref:- Harrisons Principles of Internal Medicine 20th edition; Pg num:- 1731
