Abstract
|
|
|
|
Implantable cardioverter-defibrillator (ICD) provides a significant reduction in mortality in survivors of sudden cardiac arrest and among patients at high risk for life-threatening arrhythmia. Despite proven survival benefits, ICD therapy still has drawbacks, one of the most important of which is shock delivered for causes other than ventricular tachycardia or fibrillation. Inappropriate use of shocks has multiple adverse effects, including impaired quality of life, psychiatric disturbances, and even provocation of ventricular arrhythmia. Systematic avoidance of inappropriate shocks is essential for maintaining the risk-benefit ratio in patients with ICD.
