Study on medical records of 2.632 exacerbated fast arrhythmia patients, treated in Hai Ba Trung Hospital from January 1996 to August 1999. The results: exacerbated fast arrhythmia and Wolff - Parkinson syndrome (W.P.W) were rarely forms among general cardiovascular diseases (17.96%). The disease occurred mainly in 40-69 year-old patients, the rate of female were higher than male. For W.P.W syndrome, the disease common occurred in 30-49 year-old patients, the rate of male were higher than female. Pressing eyeball was still an effective method though it was not absolute. Cordarone drug had a good effect. Electrical shock was the most effective and the last treatment method after failure in other methods

From June 2001 to Sept 2002, at Thong Nhat Hospital – Ho Chi Minh City the physioelectric method was applied, using energy of radiofrequency to treat tachycardia in 50 subjects (26 male, 24 female) with WPW syndrome, aged 14-64. This is a high efficacy method of definitive treatment dysrythsmia with low rate no severity complication, and with low rate of recurrence (2%). This method can be applied in any well equiped medical facilities in Vietnam with a well qualified medical staff, needing and expense of 1/17 verssus in other South East Asia countries and of 1/27 versus in USA

To localize bypass pathways, left and right ventricular regions were analyzed at rest by phase image analysis in 6 patients with Wolff-Parkinoson-White syndrome and 5 patients with concealed bypass pathway. These were compared with image findings in 12 normal subjects. In normal subjects, the earliest emptying occured in ventricular septal, apical and left basal segments. Mean difference between the earlist left and right ventricular phase angle was 2.3+/-5.6degrees in patients with normal conduction, -14.0+/-15.1degrees in patients with left bypass pathways, 15.0+/-0degrees in patients with right bypass pathways and -6.6+/-12.3degrees in patients with concealed bypass pathways. In patients with bypass pathways, there was complete agreement between phase and electrophysiologic maps, but incomplete agreement(4 of 6) between surface ECGs and electrophysiologic map in a patient with left posterior and left bypass pathways. The phase image represents a new, noninvasive method of evaluating ventricular pre-excitation. The method may provide useful information complementary to that of electrocardiographic and electriphysiologic analysis.

Wolff-Parkinson-White (WPW) syndrome is a relatively common electrical disorder showing paroxysmal supraventricular tachycardia. However, the familial form of WPW syndrome is rare, and is usually inherited as a Mendelian autosomal dominant trait. Here, we describe a family where a father and son both showed WPW syndrome. Their conditions were treated with radiofrequency ablation.

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.

BACKGROUND: The purpose of this study was to investigate the clinical and electro physiologic characteristics of patients with multiple accessory pathways. Recently as endocardial mapping has become more and more accurate, multiple accessory pathways which were considered to be rare in the past, have become more commonly reported in patients with Wolff-Parkinson-White syndrome. METHODS: From February 1993 to June 2000, there were a total of 452 patients, who were confirmed to have accessary pathway mediated-tachyarrhythmias diagnosed by electrophysiologic study. Among those, 19 patients had multiple accessory pathways, and were enrolled in this study. RESULTS: Among the 19 patients, thirteen patients were male and six were female, and their mean age was 36.5+/-16.17 years. All patients had 2 accessory pathways. The distribution of the location of the accessory pathways was at the left free wall (71.1%), right free wall (18.4%) and posteroseptal wall (10.5%). The most common combination pattern was the left free wall and left free wall (57.9%) and the most common anatomical areas were the left lateral wall and left posterior wall (36.8%). The success rate of the catheter ablation was 84.2% (16/19). The recurrence rate after the radiofrequency catheter ablation was 31.3% (5/16) and the most common recurrence site was left free wall (60.0%, 3/5). CONCLUSION: These results indicated that the clinical and electrophysiologic characteristics of the multiple accessory pathway patients with WPW syndrome in our study were similar to those of western countries.

The Wolff-Parkinson-White (W-P-W) syndrome and variants are called the pre-excitation sydrome. The prevalence has been estimated 0.15 pereent. Advances in electrophysiological mapping and increasing sophistication of surgical techniques have been resulted in an increasing role for definitive surgical treatment. The anesthetic management of patients with this syndrome is aimed at avoiding tachyarrhythmias. Anesthesia for surgical ablation of accessory conducting pathways was successfully performed under general balanced technique with fentantyl, vecuronium, isoflurane which were avoid of sympathetic stimulation.
