This 23-year-old woman presented with palpitations when carrying heavy materials and was found to have paroxysmal supraventricular tachycardia. She received adenosine and verapamil which terminated the arrhythmia. An electrophysiology study found atrioventricular reentrant tachycardia using an accessory pathway. Radiofrequency catheter ablation was performed and successfully eliminated conduction over the left posteroseptal and left lateral accessory pathways. She was diagnosed with manifest Wolff-Parkinson-White syndrome status post successful ablation.

1. Case presentation

2. Brief history
This 23 years old woman was healthy in the past.
She experience the first episode when she was
15-year-old during exercising and occasionally
recurred every half to one year.
This time, she presented with palpitation when
she carrying heavy materials. Due to above
problems, she was brought to LMD where PSVT
was noted. Adenosine (6mg --> 12mg) and
Isoptin 1amp (?) were administrated.
NO history of smoking and drinking.

4. After adenosine and verapamil (clear consciousness, BP: 98/79mmHg)

5. cardioversion by Amiodarone

7. Baseline

8. A1A1 pacing induced orthodromic AVRT

9. RA pacing

10. RV pacing

11. V1V2 pacing induced AVRT

13. RFCA at lateral excellent location

14. RFCA at lateral Kent

15. post RFCA at lateral AP: no VA conduction by RV pacing (CL: 350ms)

16. post RFCA at lateral AP: no VA conduction by RV pacing (CL: 300ms)

17. Posteroseptal Kent (post 1st RFCA at lateral Kent)

18. post successful RFCA at posteroseptal Kent

19. recurrent lateral VA conduction after RFCA of posteroseptal Kent

20. 2nd RFCA lateral Kent at successful spot during orthodromic AVRT

21. post successful 2nd RFCA lateral Kent

22. Final

23. Diagnosis
Manifest WPW syndrome status post
successful ablation of left
posteroseptal and left lateral Kent
