Supraventricular Tachycardia in Wpw Syndrome
In four patients with WPW syndrome atrial and ventricular premature beats were induced and the changes in form of the ventricular and atrial complexes were studied. Results indicate that, depending upon the timing of the premature atrial beat and the state of refractoriness of the His and Kent bundles, excitation of the ventricles occurs predominantly through the atrioventricular nodal system, ...
متن کاملWPW syndrome complicated by another cardiac disorder.
During the past 28 months, 16 cases of WPW syndrome were operated on at Hiroshima University Hospital. Two cases were complicated by other cardiac disorders which accelerated tachycardia, making diagnosis difficult. One of these cases showed serious mitral regurgitation, due to infective endocarditis and the patient suffered cardiac failure accompanied by paroxysmal tachycardia not responsive t...
متن کاملAn unusual WPW syndrome: What is the preexcitation variant?
A 15-year-old female with WPW syndrome and normal heart underwent an electrophysiology study for paroxysmal palpitations and syncope. Intravenous adenosine produced an unexpected response of QRS changes and advanced AV block. During isoproteronol infusion, short-lasting and poorly tolerated wide QRS tachycardia was inducible, but pacing maneuvers were not feasible during tachycardia to determin...
متن کاملWPW syndrome during pregnancy: increased incidence of supraventricular arrhythmias.
cal prolonged QT syndrome is strongly promoted by excessive adrenergic influence, such as might have arisen from the patient's septic, dehydrated state.3 Intravenous adenosine possesses a significant short-lived antiadrenergic effect.6 However, in this case any potential beneficial anti adrenergic effect was overridden by adenosine-induced bradycardia. Moreover, there is ftO'indication that the...
متن کاملTermination of spontaneous tachycardia in a patient with WPW syndrome.
1 wo previous reports have demonstrated dual AV nodal pathways as the causative mechanism of spontaneous SVT termination in the WPW syndrome. Westveer et al’ reported a patient with WPW and non-sustained antidromic SVT, where SVT termination was related to retrograde dual AV nodal pathways. Retrograde conduction of the SVT occurred over the slow retrograde AV nodal pathway with concealment into...
