2. ➢ Wolff Parkinson White (WPW) Syndrome is a congenital
disease of the heart
➢ WPW caused by the presence of an abnormal accessory
electrical conduction pathway between the atria and ventricles.
➢ It’s preexcitation syndrome.

3. We see the cross section of the heart. In WPW syndrome, there are accessory pathways that are not normally available. These paths
cause residual impulses from the sinus node to directly reach the ventricles without reaching the AV node. This can lead to various
arrhythmias.

5. In WPW syndrome
➢ some cases it cause arrhythmias
➢ Atrial fibrillation
➢ AV-Nodal reentrant tachycardia (AVNRT).
These arrhythmias can cause
➢ Palpitation
➢ Blackout
➢ Fainting

6. Tachycardia

7. Atrial Fibrillation

8. atrioventricular reentrant tachycardia

9. In WPW syndrome, complaints sometimes go
to sleep for a long time, but may reappear in
the future. Sometimes the accessory paths
lose their ability to transmit transmission and
the problem disappears. Occasionally it can
cause ventricular fibrillation, a fatal
arrhythmia.The risk of developing ventricular
fibrillation is extremely rare.

10. Frequency
The prevalence of WPW syndrome in
the population is 1 in 100,000. It is
more common in men. It is most often
diagnosed during childhood or
adolescence. It is the most common
cause of tachycardia (rapid heartbeat)
in children and adolescents.

11. Complaints
Patients do not have any complaints until tachycardia
develops. When tachycardia occurs, complaints vary
according to the type of tachycardia and how fast:

12. ➢ Palpitations
➢ Chest pain of varying degrees
➢ Dizziness, blackout, sweating, nausea
➢ Fainting (syncope)
➢ Tiredness
➢ Shortness of breath
➢ Cardiac arrest
Complaints

13. Diagnosis
-The patient's history, family characteristics and
complaints are examined.
-The heart rests with a stethoscope. If there is
palpitations at that time, the rhythm may be
regular or irregular. Its speed is between 150-
250. Blood pressure can be normal or low.
-ECG is necessarily examined. The ECG has
typical features for WPW: The ECG has a delta
wave at the beginning of the QRS complex,
indicating the extra conduction paths.
-This wave occurs even without tachycardia. If
WPW signs are not visible on the ECG, long ECG
recordings may be necessary.

14. Treatment
No treatment is required in patients who do not have
complaints or have very mild palpitations.
Catheter Ablation
➢ Highly effective and preferred treatment method
➢ Success rate is over 90% and the risk is low.

15. Pharmacological Treatment
Pre-excited tachycardia
➢ Adenosine used with caution
➢ Verapamil
Long term therapy
➢ Propafenon
➢ Sotalol
Pill-in-the-Pocket
➢ Diltiazem 120mg + Propranolol 80mg
