Cryoablation of Accessory Pathways in Children

Pacing and Clinical Electrophysiology, 2007
Background: Cryoablation is utilized for septal tachycardia substrates due its safety. Considering the recent studies which reveal coronary artery stenosis related to radiofrequency ablation (RFA) in children, cryoablation may offer advantages for nonseptal accessory pathways (APs) as well.

Is this an anteroseptal accessory pathway?

Journal of Electrocardiology
The ECG of a patient during sinus rhythm shows preexcited QRS pattern, with rS pattern in lead V1, transition in lead V2, and positive inferior leads. Following the stepwise algorithms, the location of accessory pathway (AP) was identified at anteroseptal region.

Catecholamine Dependent Accessory Pathway Automaticity

Pacing and Clinical Electrophysiology, 2004
Automaticity 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 ...

Sensory pathways in the spinal accessory nerve

The Journal of Bone and Joint Surgery. British volume, 1999
We obtained samples of spinal accessory nerve from patients undergoing radical surgery for tumours or nerve grafting in the neck. These were analysed by light and electron microscopy for the type of fibre. All contained fibres consistent with non-proprioceptive sensory function including pain.

Anteroseptal Accessory Pathway

2021
Antroseptal 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.

Recurrent tachycardias due to an accessory pathway

Journal of Electrocardiology, 1976
A 48 year old female presented with a long history of palpitations and syncopal episodes. His bundle electrogram studies were performed in order to evaluate the conduction system. The electrocardiogram (ECG) revealed normal PR and QRS intervals, while the unpaced His electrogram was normal.

Diagnosis and Treatment of Patients with Accessory Pathways

Cardiology Clinics, 1990
Of the accessory pathways, partially or totally bypassing the atrio-ventricular conduction system, the bundle of Kent is the most common type. The electrocardiographic (ECG) expression of preexcitation depends upon the contribution of the activation fronts over the AV node and the accessory pathway.
