Catecholamine Dependent Accessory Pathway Automaticity
Pacing and Clinical Electrophysiology, 2004Automaticity from extra nodal accessory pathways appears to be rare. We report the case of a man with the WPW syndrome who presented for repeat electrophysiological study and catheter ablation. After successful ablation of a para‐Hisian accessory pathway, an isoproterenol challenge produced an accelerated wide complex rhythm that was dissociated from ...

Fatigue Phenomenon in Accessory Pathways
Journal of Cardiovascular Electrophysiology, 1994Fatigue Phenomenon in APs. Fatigue phenomenon is transient failure of conduction following a period of repetitive excitation. Fatigue in iiccessory pathways is uncommon, and its electrophysiologic characteristics and clinical implications are unknown. Among the 215 patients who underwent electrophysiology studies from July 1992 to December 1993, 4 (2%)

Anteroseptal Accessory Pathway
2021Antroseptal accessory pathways are sometimes challenging because of proximity to normal conduction system and risk of AV block. Sometimes they could be ablated via noncoronary cusp of aorta.

CATHETER ABLATION OF ACCESSORY PATHWAYS
Cardiology Clinics, 1997Radiofrequency catheter ablation is a highly effective, curative treatment for arrhythmias related to accessory atrioventricular connections. Compared with medical therapy, ablation is more definitive, is more cost-effective, and is associated with a lower risk of proarrhythmia.

A suddenly lethal accessory pathway
Journal of Electrocardiology, 2012A 17-year-old girl was diagnosed with an asymptomatic Wolff-Parkinson-White pattern just before a major orthopedic operation. Three months after the surgery, she developed ventricular fibrillation-being the first manifestation of her Wolff-Parkinson-White syndrome. The patient was successfully reanimated. radiofrequency ablation permanently interrupted

Adenosine‐Dependent Concealed Accessory Pathway
Pacing and Clinical Electrophysiology, 2011Adenosine is routinely used during ventricular pacing to exclude the persistence of retrograde accessory pathways conduction after radiofrequency (RF) ablation procedures by blocking conduction over the atrioventricular node. This is the first report of an adenosine‐dependent concealed accessory pathway demonstrating transient conduction only after ...

A Mischievous Accessory Pathway
2022A 30-year-old male with electrocardiographic (ECG) evidence of manifest pre-excitation (figure 1) was referred for an electrophysiology study (EPS). Quadripolar catheters were placed in the His position (His) and right ventricular apex (RVA) and a decapolar catheter was placed in the coronary sinus (CS).

Atriofascicular Accessory Pathways
2017Uncommon accessory pathways presenting decremental properties and inserting into the right ventricle have been described as Mahaim pathways, and these fibers are distinct form of preexcitation. Those anomalous pathways are subdivided into three types, and it is recently said that most of them in fact originate from the right atrial free wall near the ...
