TL;DR: A case of coexisting atrial fibrillation and ventricular tachycardia in a patient with an implantable cardioverter defibrillator and radiofrequency ablation of the atrioventricular node is described.

Abstract: A case of coexisting atrial fibrillation and ventricular tachycardia in a patient with an implantable cardioverter defibrillator is described. Despite careful reprogramming, the device was not always able to distinguish between the two arrhythmias and continued to deliver inappropriate antitachycardia therapy including DC shocks. Attempts to pharmacologically control the atrial fibrillation were unsuccessful so radiofrequency ablation of the atrioventricular node was performed. Following successful ablation, there have been no further false detections nor episodes of further ventricular tachycardia.

The Proarrhythmic Potential of Implantable Cardioverter-Defibrillators
Sergio L. Pinski,Gerard J. Fahy +1 more
TL;DR: The proarrhythmic potential of ICD therapy can be minimized by tailoring the "electrical prescription" according to characteristics of the clinical arrhythmia and individual ICD idiosyncrasies.

Implantable Cardioverter-Defibrillators: Implications for the Nonelectrophysiologist
TL;DR: Several clinical scenarios in which the nonelectrophysiologist may be required to interact with patients who have implanted defibrillators are described, and management guidelines to facilitate delivery of optimal care when specialized staff and material resources are not available are provided.

Hospital Readmission in Patients Treated With Tiered-Therapy Implantable Defibrillators
TL;DR: Rehospitalization for cardiac reasons is common in patients receiving implantable defibrillators and is responsible for substantial resource consumption and the need for readmission for arrhythmia-related reasons cannot be predicted by clinical parameters at the time of device implantation.

Management of the patient with frequent discharges from implantable cardioverter defibrillator devices.
John M. Miller,Henry H. Hsia +1 more
TL;DR: As the number of device implants continues to grow, an increasing number of patients are experiencing frequent device discharges, and the management of these patients is the subject of this review.

TL;DR: The non‐thoracotomy lead system for this ICD displayed infrequent implant complications and proved to be reliable ai terminating arrhythmias and maintaining a low rate of sudden cardiac death in this high risk popuiation.

TL;DR: The automatic implantable cardioverter-defibrillator nearly eliminates sudden death over a long-term follow-up period in a high risk group of patients, it has an acceptable rate of complications or problems, or both, and most late deaths in these patients are nonsudden and of cardiovascular origin.

Observations on electrode-tissue interface temperature and effect on electrical impedance during radiofrequency ablation of ventricular myocardium.
David E. Haines,Anthony F. Verow +1 more
TL;DR: Maintaining electrode-tissue interface temperature at less than 100 degrees C during radiofrequency catheter ablation in the heart may avoid the complications associated with the sudden rise in electrical impedance.

TL;DR: Compared with a group of historic control subjects treated with direct-current shock ablation, the 10 patients successfully treated with radiofrequency current had significantly less creatine kinase-MB isoenzyme release and a junctional escape rhythm was present in all patients after radiofrequency-induced atrioventricular block.

High success rate of atrioventricular node ablation with radiofrequency energy

TL;DR: The use of a larger 4-mm tip electrode for delivery of radiofrequency current and a method to better localize the AV node were prospectively studied in 32 patients undergoing catheter ablation of the atrioventricular (AV) node.

Survival in patients with depressed left ventricular function treated by implantable cardioverter defibrillator.
TL;DR: It is concluded that ICD has a major impact on survival in patients with poor LV function suggesting that many of these patients die prematurely from arrhythmia causes.
