A new technique for cardioversion of chronic atrial fibrillation was used in 17 patients whose
arrhythmia had resisted all attempts at electrical and pharmacologycal cardioversion. Atrial …

Ventricular tachycardia in patients with remote myocardial infarction is thought to be due to
reentry. To improve the efficacy of catheter ablation, we sought to identify electrograms …

A power source modified to increase voltage delivery and minimise arcing (for a given
energy) was used for transvenous ablation of atrioventricular conduction to control refractory …

Ablative techniques are based on the use of the energy of a physical agent to modify the
conduction in a localized area of myocardium in order to prevent the recurrence of badly …

Abstract 35 patients with refractory supraventricular arrhythmias were treated in three
centres by high-energy shocks delivered to the atrioventricular conduction system from a …

Endocardial catheter fulguration is a new method for the treatment of cardiac arrhythmias
which has been used to interrupt the AV conduction system, to prevent rapid ventricular …

DC shocks within the coronary sinus have been abandoned because of the risk of cardiac
rupture and tamponade. Catheter ablation using DC energy to electrodes straddling the …

The introduction of radiofrequency energy for catheter ablation of accessory pathways has
offered certain advantages over high-energy direct-current shocks. With this approach …

RESULTS The arrhythmias treated were atrial fibrillation, atrial flutter, atrial tachycardia,
ventricular tachy-cardia, and ventricular fibrillation. The immediate results are summarized in …

A combination suction catheter-bipolar lead system permits precise ablation of AV
conduction with low energy. The electrode is positioned to maximize the bipolar His …
