Atrioventricuiar (AV) ablation to yield chronic first degree block was attempted in six mongrel
dogs. Radio frequency energy (RFE) at 750 KHz, ranging from 3.4 to 4.5 W, was delivered …

To determine if catheter ablation of the atrioventricular (AV) junction with radiofrequency
energy can induce chronic incomplete (first-and second-degree) AV block to avoid the need …

Ten anesthetized dogs were studied in an attempt to provoke partial alterations in
atrioventricular (AV) conduction by high-frequency current (HFC) transcatheter ablation. A …

Direct‐current or laser energy has been used to induce atrioventricular (AV) block, but
certain complications associated with this type of energy have been reported. We have …

The electrophysiology of AV nodal modification induced by radiofrequency energy (n= 5) or
a sham procedure (n= 5) was studied in ten dogs. The five dogs that received …

The correlation of histologic and electrophysiologic findings in dogs undergoing
transvenous ablation of atrioventricular (AV) conduction has not been described. The …

The utility of high-frequency current applied through the distal electrode of a conventional
electrode-catheter for altering atrio-ventricular conduction was studied in 18 anaesthetized …

Radiofrequency catheter ablation of the atrioventricular (AV) node or bundle of His was
performed in 12 adult mongrel dogs. The aim was to create chronic incomplete AV block …

This paper reviews methods for producing experimental complete atrioventricular (AV) block
in dogs, with emphasis on those methods that enable chronic AV block to be obtained. The …

A single suction electrode catheter was used for His bundle electrogram recording. His
bundle pacing, and low-energy (20 or 30 J) His bundle ablation in seven dogs. The suction …
