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 کاملElectrophysiological studies in patients with chronic recurrent ventricular tachycardia.
Seventeen consecutive patients with chronic recurrent ventricular tachycardia (VT) were studied in an attempt to delineate the reproducibility and mechanism of this arrhythmia. Six patients had nonsustained and 11 had sustained VT. The following electrophysiological techniques were utilized in an attempt to reproduce VT: 1) rapid atrial and ventricular pacing (17 pts); 2) atrial extrastimulus t...
متن کاملClinical and electrophysiological characteristics in patients with atrioventricular reentrant and atrioventricular nodal reentrant tachycardia.
AIM To compare clinical, electrophysiological characteristics and transcatheter ablation results between two groups of patients, one with atrioventricular reentrant tachycardia (AVRT) and the other with atrioventricular nodal reentrant tachycardia (AVNRT). METHODS The study population consisted of 94 consecutive patients who underwent endocavitary electrophysiological study and radiofrequency...
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...
متن کاملDoppler predictors of inducibility of atrial fibrillation in patients with WPW syndrome and atrioventricular re-entrant tachycardia.
BACKGROUND Atrial fibrillation (AF) in patients with Wolff-Parkinson-White syndrome (WPW) may induce complex ventricular arrhythmias resulting in sudden cardiac death. It is essential to find an effective non-invasive diagnostic method allowing to select patients at risk of life-threatening arrhythmias. Our objective was to examine Doppler predictors of AF in patients with WPW and atrioventricu...
