  • Wolff-Parkinson-White(WPW) syndrome is characterized by electrographic evidence of ventricular preexcitation, which predisposes to supraventicular arrhythmias. Familial occurrence of WPW syndrome is uncommon. We observed two affected siblings in a family. Five members of the family underwent 12-lead electrocardiography and echocardiography. Although known genetic abnormality of the 7q34-q36(PRKAG2) for the familial WPW syndrome was evaluated, the mutation was not detected in this family. Other unknown mutations responsible for this familial WPW syndrome were suggested.

  • From October 1993 to February 1996, 9 patients with Wolfr-Parkinson-White syndrome underwent surgical ablation of the accessory atrioventricular conduction pathways. The indications for surgical ablation we e radiofrequency ablation failure in 6 cases, multiple accessory pathways in 1 case, catheter tip fracture ducting catheter ablation in 1 case and additional procedure(redo mitral valve replacement due to valve thrombosis) in 1 case. There was no operative mortality. The postoperative complications were noted In 2 cases pericardial effusion and wound Infection. All patients had accessory atrioventricular connections ablated which were proven by surface ECG and follow-up electrophysiologic study and have remained free of symptomatic tachycardia. The indications for surgical treatment of Wolff-Parkinson-White syndrome are radiofrequency ablation failure, multiple pathways, or when additional procedures are required The present results were satisfactory.

  • Wolff Parkinson White Syndrome(WPW)은 일반인과는 다르게 선천적으로 심방과 심실 사이에 부전도로(Accessory Pathway)가 존재하여 정상 전도와 비교하였을 때, 빠른 속도로 심실을 자극하여 부정맥을 일으키는 것을 의미한다. WPW는 부정맥이 주된 증상이기는 하나, 평소에는 무증상인 경우가 많고, 성인이 되어 갑작스럽게 발생하는 경우가 존재하기 때문에 인지하지 못하고 살아가는 환자들이 많다는 것이 특징이다. 이러한 특징은 갑작스러운 건강 악화가 타인의 생명에 악영향을 줄 수 있는 트럭 운전기사나 의사와 같은 직업군 등의 경우 WPW를 조기에 발견하고 치료해 위험을 사전에 방지하는 것이 매우 중요하다. 따라서, 본 논문에서는 Electrocardiogram(ECG) 데이터를 기반으로 WPW를 자동으로 분류하기 위한 Feature Ensemble 기반 심층 학습 프레임워크를 제안한다. 제안된 기법의 경우 단일 1D-CNN과 GRU를 이용한 기법 대비 F1-Score, Accuracy 기준의 성능 향상을 달성하였기에 본 Task에 적합함을 보여준다.

  • We present the case of a healthy 28-day-old female full-term neonate who was admitted to the neonatal intensive care unit for severe metabolic acidosis, hypoglycemia, and an initial sinus rhythm. The first diagnostic hypothesis was hypovolemic shock, and fluid resuscitation was started immediately. During fluid therapy, cardiovascular collapse occurred with supraventricular tachycardia. The latter was successfully treated with adenosine and beta-blockers. After 8 days, electrocardiography showed ventricular pre-excitation, and Wolff-Parkinson-White syndrome was diagnosed. A novel variant of the MYL2 gene that is related to hypertrophic cardiomyopathy and conduction defect was found after discharge. Cardiogenic shock should be considered, despite being a rare cause of shock in neonates.

  • Purpose: The aim of the present study was to evaluate the characteristics of electrophysiologic studies (EPS) and radiofrequency ablation (RFA) performed in subjects aged less than 30 years with Wolff-Parkinson-White (WPW) syndrome, particularly pediatric patients under 18 years of age, based on our experience. Methods: Two hundred and one consecutive patients with WPW syndrome were recruited and divided to 3 groups according to age: group 1, 6 to 17 years; group 2, 18 to 29 years; and group 3, 30 to 60 years. The clinical, electrophysiological, and therapeutic data for these patients were evaluated by a retrospective medical record review. Results: A total of 73 (36%) of these patients were <30 years of age. Although there were more males than females in group 2 (male:female, 31:11), there was no sex difference in group 1 (male:female, 16:15). Left accessory pathway was detected less frequently in group 1 (32%, 10/31) than in group 2 (57%, 24/42) and group 3 (63%, 81/128) (P=0.023 and P=0.002, respectively). Conclusion: The present study describes several different electrophysiological characteristics in children and adolescents with WPW syndrome. Therefore, when EPS and RFA are performed in children and adolescence with WPW syndrome, we recommend that these characteristics be considered.

  • A 17 year old female patient with Ebstein`s anomaly received surgical treatment for WPW syndrome and AV nodal reentrant supraventricular tachycardia[SVT] Electrophysiologic study revealed that an anomalous pathway was located in the right posterolateral portion and antegrade dual AV nodal pathway responsible for AV nodal reentrant tachycardia. The patient was underwent surgery on February 18, 1987. Intraoperative mapping was used to define the location of accessory pathway. The accessory pathway was cryoablated through the epicardium. Simultaneously discrete cryoablation around the perinodal area was performed to prevent AV nodal reentrant SVT. The atrialized right ventricle of Ebstein`s anomaly was plicated with 11 pledget mattress sutures under the cardiopulmonary bypass. Two and half years after surgery, the patient has no evidence of WPW syndrome or supraventricular tachycardia.

  • Wolff Parkinson White (WPW) syndrome is a condition in which there is an aberrant conduction pathway between the atria and ventricles, resulting in tachycardia. A 42-year-old patient, who was treated for WPW syndrome previously, presented with chronic somatic pain. With her cardiac condition in mind, she was thoroughly worked up for a recurrence of disease. As part of routine screening of all patients at our pain clinic, she was found to have severe depression as per the Patient Health Questionnaire-9 (PHQ-9) criteria. After ruling out sinister causes, she was treated for depression using oral Duloxetine and counselling. This led to resolution of symptoms, and improved her mood and functional capability. This case highlights the use of psychological screening tools and diligent examination in scenarios as confusing as the one presented here. Addressing the psychological aspects of pain and adopting a holistic approach are as important as treatment of the primary pathology.

  • It is well known that multipoint and computerized intraoperative mapping systems improve the results of surgery for Wolff-Parkinson-White syndrome and show tremendous potential for opening an entirely new era of surgical intervention for the more common and lethal types of supraventricular tachyarrhythmias such as atrial flutter and atrial fibrillation. In addition, the ability to map and ablate the sometimes fleeting automatic atrial tachycardia is greatly enhanced by computerized mapping systems. In this study, we have developed 64 channel computerized data analysis system using microcomputer (Macintosh ${II}_{x}$) for basic research of electrophysiology and electrical propagation. The bipolar electrogram information is acquired from 64 cardiac sites simultaneously at a sampling rate of 1 ksampls/sec with continuous and total data storage of up to 30 seconds. When the reference electrogram is selected and reference point is picked up, delay time from the reference point is displayed on two dimensional diagram of the heart. System design permits easy expansion to almost 256 simultaneous sites. this system is expected to enable us to study pathophysiology of cardiac arrhythmia and to improve the result of diagnosis and surgical treatment for cardiac arrhythmia.

  • Purpose: Abnormal myocardial perfusion may be caused by ventricular preexcitation, but its location, extent, severity and correlation with accessory pathway (AP) are not established. We evaluated perfusion patterns on myocardial perfusion SPECT and location of AP in patients with WPW (Wolff-Parkinson-White) syndrome. Materials and Methods: Adenosine Tc-99m MIBI or Tl-201 myocardial perfusion SPECT was performed in 11 patients with WPW syndrome. Perfusion defects (PD) were compared to AP location based on ECG with Fitzpatrick's algorithm or electrophysiologic study and radiofrequency catheter ablation. Results: Patients had atypical chest discomfort or no symptom. Risk of coronary artery disease (CAD) was below 0.1 in 11 patients using the nomogram to estimate the probability of CAD. Coronary angiography was performed in 4 patients (mid-LAD 50% in one, normal in others). In 4 patients, AP localization was done by electrophysiologic study and radiofrequency catheter ablation (RFCA). Small to large extent ($11.0{\pm}8.5%$, range:$3{\sim}35%$) and mild to moderate severity ($-71{\pm}42.7%$, range:$-2l7{\sim}-39%$) of reversible (n=9) or fixed (n=1) perfusion defects were noted. One patient with right free wall (right lateral) AP showed normal. PD locations were variable following the location of AP. One patient with left lateral wall AP was followed 6 weeks after RFCA and showed significantly decreased PD on SPECT with successful ablation. Conclusion: Myocardial perfusion defect showed variable extent, severity and location in patients with WPW syndrome. Abnormal perfusion defect showed in most of all patients, but it did not seem to be correlated specifically with location of accessory pathway and coronary artery disease. Therefore myocardial perfusion SPECT should be interpreted carefully in patients with WPW syndrome.
