The electrocardiogram is notoriously unreliable for the diagnosis of ischaemic heart disease in patients with Wolff-Parkinson-White syndrome. Abnormalities in the resting tracing may lead to false positive diagnoses of inferior or anterior myocardial infarction. Although ST segment depression with exercise has been reported in patients with Wolff-Parkinson-White syndrome, the depth of depressio...

Catheter ablation is an experimental procedure that may prove useful for patients with drug-refractory supraventricular tachycardia. Current techniques involve the use of high-energy direct-current shocks, delivered via electrode catheters. These techniques have been used most commonly for ablating the atrioventricular (AV) junction in patients with supraventricular tachycardia. Such ablation m...

Transcatheter radiofrequency ablation of supraventricular tachycardia was first introduced in 1987. The procedure is now well-accepted as primary treatment for supraventricular tachycardia in paediatric patients. In this report we describe our experience of radiofrequency ablation of accessory pathway mediated supraventricular tachycardia in the past 10 years. From 1994 to 2005, 121 procedures ...

BACKGROUND Cardiac memory is a phenomenon characterized by transient T-wave abnormalities occurring during normal sinus rhythm, after a period of altered ventricular depolarization, where the T-wave vector has the same direction as the vector of the previously altered QRS complex (T-wave inversion). It is a form of electrical remodelling of the ventricular, where the T-wave follows ("remembers"...

Radiofrequency (RF) catheter ablation became first-line therapy for supraventricular tachycardia in patients with Wolff-Parkinson-White syndrome1–5 and atrioventricular (AV) nodal reentrant tachycardia (AVNRT)6–11 in the early 1990s. High ablation success ( 90%) and low complication rates ( 5%) were found by numerous investigators.1–11 This article describes these ablation techniques with a foc...

objective: in this study, the possibility of prenatal diagnosis of down syndrome with real-time pcr method was evaluated. in this context, optimization of a suitable method for purification of high quality dna from amniotic fluid samples was also considered. materials and methods: pregnant women who had the high risk of having babies with down syndrome were selected according to the biochemica...

In this retrospective study of 22 patients with the Wolff-Parkinson-White (WPW) syndrome, the cost of catheter ablation in 11 patients was compared with that of surgical ablation in another 11 patients. All patients in the catheter ablation group had a posteroseptal accessory pathway; in the surgical group, 5 patients had a left lateral accessory pathway, 3 had a left lateral and posteroseptal ...
