The clinical efficacy of ICD-CRT therapy depends on accurate sensing of intracardiac signals and sensing algorithms. We report the occurrence of sensing abnormality in a patient with ICD-CRT. In this patient, oversensing of myopotentials during strenuous muscular activity resulted in an inappropriate ICD-CRT discharge. Although modern ICDs are highly effective in detecting and terminating malig...

A 58 year-old male was referred to our institute for recurrent palpitations followed by ICD shocks. The patient had a history of ischemic cardiomyopathy (EF 25%) and had received a dual-chamber ICD two years earlier for primary prevention of sudden cardiac death. The device interrogation showed multiple episodes of tachycardia and anti-tachycardia pacing (ATP), which frequently terminated the t...

Background. This report describes the value of stored ventricular electrogram analysis in the diagnosis and management of patients experiencing minimal or no symptoms before implantable cardioverterdefibrillator (ICD) therapy. Methods and Results. The study population included 48 patients who received the Cadence Tiered Therapy Defibrillator System, an investigational third-generation ICD with ...

INTRODUCTION Information about implantable cardioverter-defibrillator (ICD) longevity is mostly calculated from measurements under ideal laboratory conditions. However, little information about longevity under clinical circumstances is available. This survey gives an overview on ICD service times and generator replacements in a cohort of consecutive ICD patients. METHODS Indications for repla...

BACKGROUND Life stresses and negative emotions, such as anxiety and depression, are associated with adverse cardiac events, including arrhythmia. Patients undergoing implantation of an automatic internal cardioverter defibrillator provide a unique opportunity to characterize these relationships since all tachyarrhythmia episodes are recorded by the device. OBJECTIVES The purpose of this study...

OBJECTIVES We describe the management and outcome of permanent pacemaker (PPM) and implantable cardioverter-defibrillator (ICD) infections in a large cohort of patients seen at a tertiary care facility with expertise in device lead extraction. BACKGROUND Infection is a serious complication of PPM and ICD implantation. Optimal care of patients with these cardiac device infections (CDI) is not ...

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...

811 The first cardiac implantable electronic device (CIED), the electronic pacemaker, maintains cardiac contraction during bradycardia. The implantable cardioverter-defibrillator (ICD) manages ventricular tachycardia (VT) or fibrillation (VF) and saves lives primarily through the use of high-energy shocks. The cardiac resynchronization therapy (CRT) device restores interventricular and intraven...

BACKGROUND The implanted cardioverter defibrillator (ICD) improves survival in high-risk cardiac patients. This analysis from the MADIT-II trial database examines the long-term clinical course and subsequent mortality risk of patients after termination of life-threatening ventricular tachyarrhythmias by an ICD. METHODS AND RESULTS Life-table survival analysis was performed, and proportional h...

Abstract Background Device-related infection is the most common serious complication in patients with cardiac implantable electronic devices (CIED). Staphylococcus aureus accounts for up to 30% of CIED-related infections. There a lack scientific literature investigating risk bacteremia (SAB) CIED-patients. Purpose We aimed describe SAB Danish CIED through years 2000–2018 compared background pop...
