LGL is usually categorized in a class of preexcitation syndromes that includes the Wolff-Parkinson-White syndrome (WPW), LGL, and Mahaim-type preexcitation. (medscape.com)
Ventricular5
The clinical manifestations of WPW syndrome reflect the associated tachyarrhythmia episodes-rather than the anomalous ventricular excitation per se. (medscape.com)
A form of ventricular pre-excitation characterized by a short PR interval and a long QRS interval with a delta wave. (rush.edu)
A form of ventricular pre-excitation characterized by a short PR interval and a normal QRS complex. (sdsu.edu)
Forma de pre-excitación ventricular caracterizada por un intervalo PR corto y un intervalo QRS largo con una onda delta. (bvsalud.org)
Arrhythmogenic right ventricular cardiomyopa- thy, another hereditary arrhythmia type, also shows high genetic heterogeneity and variable expressivity. (bvsalud.org)
Syndrome1
WPW syndrome is not the only form of preexcitation, but it is the most common. (rjmatthewsmd.com)
Form1
F. The most common form of paroxysmal supraventricular tachycardia (PSVT) is AV nodal reentry due to dual pathways of excitation in the region of the AV node (see Figure 1). (rjmatthewsmd.com)
Long1
However, when such a condition occurs, it will be hard to manage since pre-excitation will be induced as long as the aneurysm persists. (bvsalud.org)
Nodoventricular2
En este síndrome, el impulso auricular viaja hasta el ventrículo por las fibras de Mahaim que conectan el NÓDULO AURICULOVENTRICULAR directamente con la pared ventricular derecha (vía nodoventricular) o con la RAMA DERECHA DEL HAZ DE HIS (vía nodofascicular). (bvsalud.org)
In this syndrome, the atrial impulse travel to the ventricle via the MAHAIM FIBERS which connect ATRIOVENTRICULAR NODE directly to the right ventricle wall ( NODOVENTRICULAR ACCESSORY PATHWAY ) or to the RIGHT BUNDLE BRANCH OF HIS (nodofascicular accessory pathway). (bvsalud.org)
Tachycardia1
See 'Electrocardiographic findings' below and "Lown-Ganong-Levine syndrome and enhanced atrioventricular nodal conduction" and "Atriofascicular ("Mahaim") pathway tachycardia" . (medilib.ir)
Conduction3
Mahaim I. Kent's fibers and the A-V paraspecific conduction through the upper connections of the bundle of His-Tawara. (medscape.com)
In 1943, the ECG features of preexcitation were correlated with anatomic evidence for the existence of anomalous bundles of conducting tissue that bypassed all or part of the normal atrioventricular (AV) conduction system. (medilib.ir)
In some patients with left free wall accessory pathways, pacing the left atrium via the coronary sinus, in an area closer to the accessory pathway, may be necessary to bring out antegrade accessory pathway conduction and overt preexcitation. (medilib.ir)
Atrial impulse1
The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute. (lookformedical.com)
