Abstract: Background and Aims: Wolff-Parkinson-White Syndrome is a congenital anomaly with delta wave in electrocardiogram representing an accessory conducting pathway. The aim of the present study was to evaluate the characteristic features of patients who underwent electrophysiological study and radiofrequency ablation at Shahid Gangalal National Heart Centre. Methods: One hundred ninety eight patients with Wolff-Parkinson-White syndrome were divided in to three age groups; 1) 8 to 17, 2) 18 to 29 and 3) 30 to 70 years. The clinical, electrophysiological and therapeutic data of these patients were taken retrospectively from the hospital records. Result: A total of 10 (5%) of these patients were less than 18 years of age. There was no sex difference in group 1 and 2. There were significantly more male patients in group 3. There were fewer patients with left sided accessory pathway in group 1 compared to group 2 and 3 (p=0.024 and p=0.002, respectively). Conclusion: This study describes several different electrophysiological characteristics in patients with Wolff-Parkinson-White syndrome. The study showed that the detection of left side accessory pathway was less frequent in children and adolescents with Wolff-Parkinson- White syndrome as well as no gender preponderance in this age group.

Arquivos Brasileiros de Cardiologia , 2005, DOI: 10.1590/S0066-782X2005000200015
Abstract: the wolff-parkinson-white syndrome (wpw) and sinus venosus atrial septal defect (asd) association is very rare and not yet reported in the literature. it is the main basis for this case report.
Electrophysiological evaluation of Wolff-Parkinson-White Syndrome  [cached]

Abstract: Sudden death might complicate the follow-up of symptomatic patients with the Wolff-Parkinson-White syndrome (WPW) and might be the first event in patients with asymptomatic WPW. The risk of sudden death is increased in some clinical situations. Generally, the noninvasive studies are unable to predict the risk of sudden death correctly . The electrophysiological study is the best means to detect the risk of sudden death and to evaluate the nature of symptoms. Methods used to define the prognosis of WPW are well-defined. At first the maximal rate of conduction through the accessory pathway is evaluated; programmed atrial stimulation using 1 and 2 extrastimuli delivered at different cycle lengths is then used to determine the accessory pathway refractory period and to induce a supraventricular tachycardia. These methods should be performed in the control state and repeated in adrenergic situations either during exercise test or more simply during a perfusion of small doses of isoproterenol. The induction of an atrial fibrillation with rapid conduction through the accessory pathway (> 240/min in control state, > 300/min after isoproterenol) is the sign of a form of WPW at risk of sudden death.
Wolff-Parkinson-White Syndrome and Rheumatic Mitral Stenosis: an Uncommon Coincidence that can Cause Severe Hemodynamic Disturbance  [cached]

Abstract: The combination of rheumatic mitral stenosis and Wolff-Parkinson-White syndrome is a rare situation. In this case, we are reporting an 72-year-old man presenting with multi-organ failure due to the this combination and successfully treated with radiofrequency ablation during preexcitated atrial fibrillation.
Safety of amiodarone usage in patients with Wolff-Parkinson-White syndrome and atrial fibrillation  [cached]

Abstract: Amiodarone is one of the basic antiarrhytmic drugs for atrial fibrillation treatment. However application of amiodarone in patients with atrial fibrillation and Wolff-Parkinson-White syndrome can induce ventricular fibrillation. Amiodarone usage in these patients should be accompanied by readiness for performance of resuscitation. This is confirmed by clinical case presentation.

Abstract: wolff parkinson white syndrome is a cardiac abnormality that affects 0.1-3 ? of the general population. diagnosis is based on the finding of preexcitation in the electrocardiogram and a history of palpitations. usual clinical presentation are paroxystic episodes of palpitations, which are benign; but sudden cardiac death risk is higher among wolff parkinson white syndrome patients than in the general population. the treatment for these patients has changed during the last few years after the development of curative radiofrecuency ablation techniques, with a high probability of success but with some potential risk. primary health care physicians should make the diagnosis and send to the cardiologist those special cases that might need complex diagnostic tests or that may need a curative ablation procedure because of their risk or their symptoms.
Left ventricular noncompaction associated with hypertrophic cardiomyopathy and Wolff-Parkinson-White syndrome  [PDF]

Health (Health) , 2010, DOI: 10.4236/health.2010.23029
Abstract: We report a 35-year-old female patient with hypertrophic cardiomyopathy, left ventricular noncompaction, and Wolff-Parkinson-White EKG pattern. Several other family members present the same clinical condition. We speculate that this phenotype is related to the genotypes PRKAG2 and LAMP2 represented by mutations of the genes encoding AMP-activated protein kinase (PRKAG2) and lysosome associated membrane protein 2 (LAMP2).

Abstract: Wolff-Parkinson-White (WPW) syndrome is one of the pre-excitation syndromes in which activation of an accessory atrioventricular (AV) conduction pathway leads to bypass the AV node and cause earlier ventricular activation than the normal pathway. We report a patient with intermittent WPW syndrome who repeatedly manifested pre-excitation after subarachnoid block.

Abstract: since the first description of the disease now known as wolff-parkinson-white syndrome, much knowledge has been gained through several experimental and clinical studies all over the world. the instituto nacional de cardiología ignacio chávez in mexco city has not been the exception. in this report, we describe the clinical, electrocardiographic and electrophysiologic contributions of past and present researchers at the institute, as well as the experience in the diagnosis and treatment of the w-p-w syndrome at this instituto nacional de cardiología ignacio chávez.
The Use of Trans-Esophageal Electrophysiology Study to Identify a High Risk Asymptomatic Wolff Parkinson White Syndrome Patient  [PDF]

Abstract: Patients with a Wolff-Parkinson-White (WPW) pattern on their ECG can experience symptoms such as syncope, palpitations, supraventricular tachycardia, and atrial fibrillation, or they can be asymptomatic (aWPW). All patients with WPW, regardless of the presence or absence of symptoms, are at risk of sudden death. Therefore, it is recommended that younger patients with WPW undergo studies to determine their risk. We report a previously asymptomatic WPW patient identified as high risk for sudden death due to rapid conduction down her accessory pathway during atrial fibrillation induced during a trans-esophageal electrophysiology study.
