Treating tachyarrhythmias with radiofrequency catheter ablation

Dimensions of Critical Care Nursing, 2000
Fast, safe, and effective, radiofrequency catheter ablation is becoming more common as a treatment for tachyarrhythmias. This article describes the procedure, which patients are eligible for it, and nursing considerations before, during, and after the procedure.

Soft Thrombus Formation in Radiofrequency Catheter Ablation

Pacing and Clinical Electrophysiology, 2002
DEMOLIN, J.M., et al.: Soft Thrombus Formation in Radiofrequency Catheter Ablation. During RF catheter ablation, local temperature elevation can result in coagulum formation on the ablation electrode, resulting in impedance rise. A recent study has also demonstrated the formation of a so‐called soft thrombus during experimental ablations. This deposit

Advanced radiofrequency catheter ablation in canine myocardium

American Heart Journal, 1994
Current radiofrequency (RF) ablation technology is limited by small lesion size. To enhance the size of RF-induced left ventricular (LV) endocardial lesions, we evaluated the effects of an enlarged distal electrode tip and increased RF power on lesion volume.

Neonatal Radiofrequency Catheter Ablation of Junctional Tachycardias

Journal of Interventional Cardiac Electrophysiology, 1997
Junctional tachycardias comprise several arrhythmia types with differing mechanisms, principally involving the region of the atrioventricular (A-V) junction. Neonatal radiofrequency catheter ablation has typically been reserved for life-threatening, drug-refractory cases due to the unique concerns regarding patient size and development.

Acute radiodermatitis after radiofrequency catheter ablation

Journal of the American Academy of Dermatology, 1997
Radiofrequency (RF) catheter ablation is used in the treatment of a variety of arrhythmias. This report describes the development of acute radiodermatitis after two prolonged RF catheter ablation procedures for supraventricular tachycardia. It also reviews the characteristics and treatment of radiation-induced skin reactions.

Radiofrequency Catheter Ablation of Refractory Ventricular Tachycardia

Pacing and Clinical Electrophysiology, 1988
Transcatheter radiofrequency ablation of the arrhythmia focus was attempted in a 68‐year‐old patient with recurrent ventricular tachycardia, both spontaneous and inducible by programmed ventricular stimulation despite treatment with multiple antiarrhythmic drugs. The procedure was performed under local anesthetic without complication.

Radiofrequency catheter ablation in symptomatic ventricular arrhythmia

Australian and New Zealand Journal of Medicine, 1997
Abstract Background: Radiofrequency catheter ablation (RFCA) is an effective method to cure both supraventricular and ventricular arrhythmia (VA) in certain centres. Aim: To assess the results of RFCA in VA at Siriraj Hospital. Method: Electrophysiologic study, mapping, using both earliest endocardial activation and pace mapping, and ablation were ...

Myocardial Temperature Response During Radiofrequency Catheter Ablation

Pacing and Clinical Electrophysiology, 1995
During radiofrequency catheter ablation, steady‐state electrode‐tissue interface temperatures are reached within 5 seconds. Within the myocardium, however, a much slower temperature rise has been observed in vitro with stabilization after approximately 2 minutes.

Radiofrequency catheter ablation in recurrent ventricular tachycardia

European Heart Journal, 1991
Catheter ablation by radiofrequency energy was carried out in 10 patients with one type of recurrent monomorphic sustained ventricular tachycardia resistant to medical antiarrhythmic management. Electrophysiological studies before ablation included activation and pace-mapping.

Radiofrequency catheter ablation for postinfarct ventricular tachycardia

Current Opinion in Cardiology, 1999
Catheter mapping and radiofrequency ablation of postinfarct sustained ventricular tachycardia (VT) remain one of the greatest challenges for the electrophysiologist. Although there were no major breakthroughs during the past year, several refinements and clarifications of existing mapping criteria were published.
