Inappropriate Implantable Cardioverter-Defibrillator Shocks

چکیده
Results A total of 1,544 ICD patients (79% male, age 61 13 years) were included in the analysis. During the follow-up period of 41 18 months, 13% experienced 1 inappropriate shocks. The cumulative incidence steadily increased to 18% at 5-year follow-up. Independent predictors of the occurrence of inappropriate shocks included a history of atrial fibrillation (hazard ratio [HR]: 2.0, p 0.01) and age younger than 70 years (HR: 1.8, p 0.01). Experiencing a single inappropriate shock resulted in an increased risk of all-cause mortality (HR: 1.6, p 0.01). Mortality risk increased with every subsequent shock, up to an HR of 3.7 after 5 inappropriate shocks.

Inappropriate Shocks in Patients with ICDs: Single Chamber versus Dual Chamber
BACKGROUND Despite the technological evolution of the implantable defibrillator, one of the questions that remains is the possible benefit of the dual chamber versus single chamber implantable cardioverter defibrillator (ICD) in reducing inappropriate shocks. OBJECTIVE To evaluate which type of device provides fewer inappropriate shocks (dual chamber versus single chamber) in patients with im...
متن کاملHealthcare Utilization and Expenditures Associated With Appropriate and Inappropriate Implantable Defibrillator Shocks.
BACKGROUND In patients with implantable cardioverter-defibrillators, healthcare utilization (HCU) and expenditures related to shocks have not been quantified. METHODS AND RESULTS We performed a retrospective cohort study of patients with implantable cardioverter-defibrillators identified from commercial and Medicare supplemental claims databases linked to adjudicated shock events from remote ...
متن کاملDownloadable algorithm to reduce inappropriate shocks caused by fractures of implantable cardioverter-defibrillator leads.
BACKGROUND The primary method for monitoring implantable cardioverter-defibrillator lead integrity is periodic measurement of impedance. Sprint Fidelis leads are prone to pace-sense lead fractures, which commonly present as inappropriate shocks caused by oversensing. METHODS AND RESULTS We developed and tested an algorithm to enhance early identification of lead fractures and to reduce inappr...
متن کاملMultiple shocks after upgrade of an implantable cardioverter-defibrillator to a cardiac resynchronization therapy-defibrillator device.
Inappropriate shocks from implantable cardioverter-defibrillators (ICDs) may occur for many reasons. Inappropriate shocks are not simply painful inconveniences for patients; they also may result in the need for further operative procedures, and sometimes even death. Herein, we report the case of a patient who after upgrade of an ICD to a cardiac resynchronization therapy-defibrillator device (C...
متن کاملArrhythmia/Electrophysiology Downloadable Software Algorithm Reduces Inappropriate Shocks Caused by Implantable Cardioverter-Defibrillator Lead Fractures A Prospective Study
Background—Downloadable software upgrades are common in consumer electronics but not in implantable medical devices. Fractures of implantable cardioverter-defibrillator (ICD) leads present commonly as inappropriate shocks. A lead-integrity alert (LIA) designed to reduce inappropriate shocks is the first software download approved to enhance nominally functioning, previously implanted ICDs. Meth...
