Sequential Inappropriate Subcutaneous Implantable Cardioverter-Defibrillator Shocks

Inappropriate Implantable Cardioverter-Defibrillator Shocks

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...

Subcutaneous implantable cardioverter-defibrillator.

or nearly 3 decades, the implantable cardioverter-defibrillator (ICD) has been available to patients who survived life-threatening rapid heart rhythms or are at risk of experiencing them. The ICD comprises a device generator coupled with a defibrillation lead. Traditional ICDs are implanted under the skin with the generator positioned beneath the collar bone. The defibrilla-tion lead is inserte...

Subcutaneous implantable cardioverter defibrillator.

Tactics for the reduction of inappropriate implantable cardioverter defibrillator shocks.

he implantable cardioverter-defibrillator (ICD) reduces mortality when used for primary or secondary prevention of sudden cardiac death in patients at high risk for life-threatening arrhythmias. In the era of singlechamber ICD, atrial fibrillation (AF) was the most common cause of inappropriate shocks, responsible for up to 62% of these.1 The issue still constitutes a major challenge, even afte...

Minimizing inappropriate or "unnecessary" implantable cardioverter-defibrillator shocks: appropriate programming.

Life-saving shocks are the raisons d’être of implantable cardioverter-defibrillators (ICDs). Paradoxically, shocks also cause much of the morbidity associated with ICDs. Consistently, shocks reduce quality of life,1,2 and rarely, they may cause proarrhythmia.3,4 Additionally, shocks have been reported to be associated with excess mortality.5 Experts disagree about whether shocks are responsible...
