Prevention of inappropriate ICD shocks in patients with Brugada syndrome

Clinical Research in Cardiology, 2009
In Brugada syndrome implantable cardioverter defibrillator (ICD) therapy is associated with a high rate of inappropriate therapies, mainly due to supraventricular tachyarrhythmias (SVT) (2.7-14.1%/year). Aim of the present study was to evaluate a single ventricular fibrillation (VF) detection zone with a high cut-off rate with respect to prevention of ...

Inappropriate ICD Therapy Due to Proarrhythmic ICD Shocks and Hyperpolarization

Pacing and Clinical Electrophysiology, 2004
A 50‐year‐old man with an ischemic cardiomyopathy underwent ICD implantation for inducible ventricular fibrillation (VF). Sixteen months later he experienced inappropriate ICD therapy due to atrial fibrillation with a rapid ventricular response. The initial shock resulted in the initiation of VF (proarrhythmia) and the patient received an additional ...

Neglected lead tip erosion: An unusual case of S-ICD inappropriate shock

Journal of Cardiovascular Electrophysiology, 2020
AbstractA 52‐year‐old man experienced a subcutaneous implantable cardioverter‐defibrillator (S‐ICD) inappropriate shock due to electrode tip decubitus. The device, implanted two years before with a three‐incision technique, was extracted, and a new electrode was implanted along the contralateral parasternal line with a two‐incision technique, in a one ...

Inappropriate shocks in the subcutaneous ICD: Incidence, predictors and management

International Journal of Cardiology, 2015
The entirely subcutaneous implantable cardioverter-defibrillator (S-ICD) eliminates the need for transvenous leads, and therefore has the potential to improve lead-longevity and reduce lead-related complications. The S-ICD has a morphology-based sensing algorithm of which inappropriate shocks have been reported.We analyzed the incidence, predictors and

Inappropriate ICD Shocks Caused by External Electrical Noise

New England Journal of Medicine, 2009
To the Editor: Because of the growing number of patients worldwide who are receiving implantable cardioverter–defibrillators (ICDs)1 and the increasing number of indications for their use, physicia...

Optimal programming of ICDs for prevention of appropriate and inappropriate shocks

Current Treatment Options in Cardiovascular Medicine, 2008
Expansion of indications for implantable cardioverter-defibrillators (ICDs) has led to a significant increase in the number of patients receiving ICDs and the number of lives saved because of ICD therapy. However, appropriate or inappropriate shocks are frequent and may result in a significant decrease in quality of life in patients with ICDs.

[Inappropriate ICD shocks after collision with a pole].

Nederlands tijdschrift voor geneeskunde, 2016
A 60-year-old man experienced inappropriate ICD shocks after collision with a pole. Cine-fluoroscopy demonstrated lead fracture of the proximal lead, which was not so clearly visible on the chest radiograph. He underwent lead extraction and implantation of a new ICD system.

Prevention of Inappropriate Shocks in ICD Recipients: A Review of 10,000 Tachycardia Episodes

Pacing and Clinical Electrophysiology, 2007
Background: The efficacy of dual‐chamber ICD arrhythmia classification algorithms is crucial to prevent inappropriate shocks. We report our experience from a meta‐analysis of five prospective clinical studies with inclusion phases ranging between 1997 and 2003. Methods: Dual‐chamber ICD using standard dual‐chamber arrhythmia

Performance of an ICD algorithm to detect lead noise and reduce inappropriate shocks

Journal of Interventional Cardiac Electrophysiology, 2016
Implantable cardioverter-defibrillators (ICD) provide treatment for life-threatening ventricular tachyarrhythmias. Failure of the pace/sense conductor of an ICD lead can cause noise on the sensing electrogram (EGM) that may be misinterpreted as ventricular activity, triggering inappropriate therapy.

Inappropriate Shock: A Failure of SVT Discriminators in a Dual Chamber ICD?

Pacing and Clinical Electrophysiology, 2006
Inappropriate shock remains a major issue in patients with implantable cardioverter defibrillators. We examine an inappropriate shock delivered in a patient with atrial tachycardia that conducted 1:1. We reconstruct the device algorithms that led to therapy delivery and discuss programming changes that could be considered.
