Radiofrequency catheter ablation is the treatment of choice in atrioventricular nodal
reentrant tachycardia. Electrophysiologic investigations in 623 patients revealed eight …

One hundred patients received selective radiofrequency ablation of retrograde fast pathway
(32 patients, group I) or slow pathway (68 patients, group II) to teat drug-refractory …

BACKGROUND The safety and efficacy of selective fast versus slow pathway ablation using
radiofrequency energy and a transcatheter technique in patients with atrioventricular nodal …

BACKGROUND Residual slow pathway conduction in the form of persistent jump in the
atrioventricular (AV) conduction time or atrial echo beats is a common finding after …

Previous studies have reported only short-term (6 to 10 months) follow-up after ablation of
atrioventricular (AV) nodal reentrant tachycardia by using the anterior approach. The …

Background: Radiofrequency (RF) catheter ablation is highly effective with a low
complication rate. However, lesions created by RF energy are irreversible, inhomogeneous …

AV block can be elicited by different mechanisms5-15: a) inadvertent damage to the AV
node or His bundle; b) a lesion of both the fast and slow pathways during serial attempts at …

Objectives. We compared the electrophysiologic effects on atrioventricular (AV) node
physiology of selective “fast” versus selective “stow” pathway radiofrequency ablation in 42 …

Radiofrequency catheter ablation was performed in 302 consecutive patients with drug
refractory atrioventricular (AV) node reentrant tachycardia. Fast pathway ablation was …

Atrioventricular (AV) node reentrant tachycardia (AVNRT) is the most common cause of
paroxysmal supraventricular tachycardia (1). Many electrophysiologic data suggest that the …
