Healthcare After Implantable Cardioverter-Defibrillator Shocks

Improper Implantable Cardioverter Defibrillator Shocks

The second ECG recorded supraventricular tachycardia at the time his hemodynamic status deteriorated and decision was made to perform electrical cardioversion with 120 Joules of biphasic synchronized direct current with follow up ECG that showed atrial paced rhythm (Figure 1B). His condition improved and started on amiodarone 200 mg, anticoagulation, and subsequent follow up for ICD reprogrammi...

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...

Prognostic Significance of Implantable Cardioverter-Defibrillator Shocks

Multiple 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...

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...
