Atrial fibrillation was induced during an electrophysiology study in 10 patients with the Wolff-Parkinson-White (WPW) syndrome, after determination of baseline properties of the accessory atrioventricular (AV) connection; intravenous propranolol (0.2 mg/kg) was then administered. Atrial fibrillation terminated during the drug infusion in three patients, allowing determination of propranolol's e...
Clinical and electrocardiographic findings for 30 patients with the pre-excitation syndrome are described together with details of treatment. Nineteen (63%) were younger than 2 years, 14 of whom were under 2 months. Sixteen infants and 7 children (77%) presented with paroxysmal supraventricular tachycardia, 14 (61%) of whom had the electrocardiographic pattern of type A Wolff-Parkinson-White (W...
Clinical electrophysiologic studies in patients with Wolff-Parkinson-White syndrome (WPW) suffering from ventricular fibrillation have shown a high prevalence of short anterograde refractory period of the accessory pathway (less than or equal to 250 ms), short preexcited RR intervals during atrial fibrillation (less than or equal to 250 ms), and multiple accessory pathways. Unfortunately the sp...
BACKGROUND Some patients with hypertrophic cardiomyopathy (HCM) or left ventricular hypertrophy also present with skeletal myopathy and Wolff-Parkinson-White (WPW) syndrome; mutations in the gene encoding the lysosome-associated protein-2 (LAMP-2) have been identified in these patients, suggesting that some of these patients have Danon disease. In this study we investigated the frequency of LAM...
What then are the criteria to select patients of Asymptomatic WPW who may be predisposed to SCD? The markers identified for SCD include: 1. Anterograde effective refractory period of accessory pathway (APERP) 240250ms; (on isoproternol APERP <200ms?) 2. Shortest Preexcited RR interval (SPERRI) less than 250ms during or induced AF. 3. Multiple accessory pathways 4. Ebsteins anomaly 5. Familial W...
Isoarea maps during the PQRST sequence were computed in 22 healthy subjects and 48 patients with Wolff-Parkinson-White (WPW) syndrome. Thirty-eight patients with WPW were on no medication and 10 were treated with class I, II, or III antiarrhythmic drugs. Seventeen isoarea maps were recorded before and 17 were recorded after accessory pathway ablation. One patient had intermittent preexcitation....
Patient with Wolff-Parkinson-White Syndrome undergoing Non-Cardiac Surgery. Perioperative Management
Background: Perioperative management of patients with preexcitation may become quite challenging, especially if there is no time for adequate preoperative investigation and clinical optimization, as in emergencies, or even worse, undiagnosed cases. It possible that the poorly controlled unknown underlying electrophysiological abnormality will unmasked during anesthesia surgery, giving rise to p...
Abstract In Europe, 350,000 people die suddenly and unexpectedly every year. The majority of sudden deaths are caused by cardiac alterations known as death (SCD). interpretation medicolegal findings is especially difficult in those SCDs where there no morphological correlate antemortem electrocardiograms or relevant medical history available. Wolff-Parkinson-White (WPW) syndrome, which an acces...
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.
