Wolf–Parkinson–White Syndrome

WPW syndrome is a disorder characterized by all of the following EXCEPT

[A] Preexcitation on the baseline electrocardiogram
[B] At least three accessory pathway that predispose to tachyarrhythmias
[C] Symptomatic tachyarrhythmias
[D] Can cause sudden cardiac death

ANSWER

[B] At least three accessory pathway that predispose to tachyarrhythmias

Feedback
WPW syndrome is a disorder characterized by the presence of at least one accessory pathway (AP) that can predispose people to atrial/ventricular tachyarrhythmias and even sudden cardiac death.

This diagnosis is reserved only for patients who have
preexcitation on the baseline electrocardiogram
symptomatic tachyarrhythmias.

In the absence of symptoms- it is preferred the term Wolff–Parkinson–White pattern.

Classic triad of electrocardiographic findings in Wolff-Parkinson-White syndrome are all EXCEPT

[A] Short PR interval
[B] Wide QRS complex
[C] Delta wave
[D] PSVT

ANSWER

[D] PSVT

The classic triad of electrocardiographic findings in Wolff-Parkinson-White syndrome: short PR interval, broad QRS complex and delta wave.

ALL are TRUE about type A pre-excitation EXCEPT

[A] Right atrioventricular connections
[B] Positive R wave is seen in V1
[C] Positive delta
[D] RR intervals of less than 250 ms suggest a higher risk pathway

ANSWER

[A] Right atrioventricular connections

Type A pre-excitation (left atrioventricular connections) – positive R wave is seen in V1 (“positive delta”) on the precordial leads of the electrocardiogram

Type B pre-excitation (right atrioventricular connections) – a predominantly negative delta wave is seen in lead V1 (“negative delta”)

Left atrioventricular connections – Left-sided accessory pathway :
– Produces a positive delta wave in all precordial leads
– R/S > 1 in V1
– Known as a Type A WPW pattern

What is the name of accessory pathway in WPW Syndrome?

[A] Bundle of Kent
[B] Bachmann bundle
[C] Purkinje fibers
[D] Mahaim accessory pathways

ANSWER

[A] Bundle of Kent

Most common congenital heart defect associated with Wolff-Parkinson-White syndrome

[A] ASD
[B] VSD
[C] Tetralogy Of Fallot
[D] Ebstein anomaly

ANSWER

[D] Ebstein anomaly
