What is the bundle of Kent and what does it cause?
Bundle of Kent Problems arise when this pathway creates an electrical circuit that bypasses the AV node. The AV node is capable of slowing the rate of conduction of electrical impulses to the ventricles, whereas the bundle of Kent lacks this capability.
What medications should not be taken with WPW?
In particular, avoid adenosine, diltiazem, verapamil, and other calcium-channel blockers and beta-blockers. They can exacerbate the syndrome by blocking the heart’s normal electrical pathway and facilitating antegrade conduction via the accessory pathway [2, 5].
What is Wolff Parkinson White Syndrome explain its pathophysiology?
In Wolff-Parkinson-White (WPW) syndrome, an extra electrical pathway between your heart’s upper chambers and lower chambers causes a rapid heartbeat. In Wolff-Parkinson-White (WPW) syndrome, an extra electrical pathway between your heart’s upper and lower chambers causes a rapid heartbeat.
What is a Kent bundle?
Bundle of Kent is an abnormal pathway present in a small percentage of the general population that results in a condition known as Wolff-Parkinson-White syndrome (WPW). The anatomic substrate is a band of myocytes that bridges the fibrous junction between the atrium and the ventricle.
Can you use amiodarone in WPW?
Conclusions. Intravenous amiodarone might be an alternative for acute treatment of AF and WPW syndrome in patients characterized by stable hemodynamics, relatively low admission heart rate, few comorbidities, elder age, and no prior syncope.
How is tachycardia treated in WPW?
It should be treated in the same way as AV nodal reentrant tachycardia (AVNRT), by blocking AV node conduction with (1) vagal maneuvers (eg, Valsalva maneuver, carotid sinus massage, splashing cold water or ice water on the face), (2) IV adenosine 6-12 mg via a large-bore line (the drug has a very short half-life) in …
What is the difference between SVT and Wolff-Parkinson-White?
What is SVT? Supraventricular tachycardia (SVT) refers to a group of abnormal fast heart rhythms that arise because of a problem involving the upper chambers of the heart. WPW is short for Wolf-Parkinson White syndrome which is a special form of SVT.
What are the subtypes of left bundle branch tachycardia?
One distinct subcategory of WCTs are those that present with a “typical” or “classic” left bundle branch block pattern. These tachycardias may be supraventricular or ventricular in origin and arise from functional or fixed aberrancy, bystander or participating atriofascicular pre-excitation, and bundle branch reentry.
What is tachycardia induction?
Tachycardia induction occurs when a paced ventricular beat finds the retrograde right bundle branch refractory. If slow (delayed) retrograde conduction through the left bundle branch occurs, the right bundle branch will recover and be capable of antegrade reactivation resulting in macroreentry (Figure (Figure8).8).
What is the bundle of Kent?
The bundle of Kent is an abnormal extra or accessory conduction pathway between the atria and ventricles that is present in a small percentage (between 0.1 and 0.3%) of the general population.
What is the bundle of Kent pathway in WPW?
In WPW the accessory pathway is often referred to as the Bundle of Kent, or atrioventricular bypass tract. Tachyarrhythmias can be facilitated by: Formation of a reentry circuit involving the accessory pathway, termed atrioventricular reentry tachycardias (AVRT)
