BACKGROUND: In the chronic atrioventricular block (CAVB) dog model, beat-to-beat variation of repolarization in the left ventricle (LV) quantified as short-term variability of the left monophasic action potential duration (STVLVMAPD) increases abruptly upon challenge with a pro arrhythmic drug. This increase occurs before the first ectopic beat (EB), specifically in subjects that demonstrate subsequent repetitive Torsade de Pointes arrhythmias (TdP). OBJECTIVE: Demonstrate that STV is feasible to monitor arrhythmic risk through the use of the intracardiac electrogram (EGM) derived from the right ventricle (RV) lead from pacemakers or implantable cardioverter defibrillators (ICD)...

RATIONALE: Brugada syndrome (BrS) is characterized by ST segment elevation at the J point ≥2 mm in the right precordial electrocardiogram (ECG) leads, in the absence of structural heart disease, electrolyte disturbances, or ischemia. It is a well-described cause of sudden death in young patients, especially in the age of between 30 and 40 years old. Here, we reported an unusual case of electrical storm (ES) of ventricular fibrillation (VF) caused by BrS with complete right bundle-branch block (CRBBB) in a 75-year-old male patient...

In spite of its effectiveness, implantable cardioverter defibrillator (ICD) patients face psychological problems such as shock-related anxiety due to device shocks. The aim of this study was to evaluate whether a web-based intervention program for ICD patients would reduce shock-related anxiety and improve quality of life compared with usual care. This was a randomized controlled trial study including a total of 76 patients. Data were collected using Turkish versions of the Florida Shock Anxiety Scale and Short Form Health Survey (SF-36) at 0 (baseline), 3, and 6 months...

OBJECTIVE: The implantable cardioverter defibrillator (ICD) is the treatment of choice for prevention of sudden cardiac death. However, a subgroup of ICD patients experiences psychological adjustment problems post implant. To date, positive psychological constructs (e.g. optimism) have been understudied in this population. Hence, we examined the association between optimism and anxiety, depression, and health status at 12-months post implant. METHODS: Patients (N=171) enrolled in the WEB-based distress management study for ICD patients were included in the analyses...

BACKGROUND: In US clinical practice, many patients who undergo placement of an implantable cardioverter-defibrillator (ICD) for primary prevention of sudden cardiac death receive dual-chamber devices. The superiority of dual-chamber over single-chamber devices in reducing the risk of inappropriate ICD shocks in clinical practice has not been established. The objective of this study was to compare risk of adverse outcomes, including inappropriate shocks, between single- and dual-chamber ICDs for primary prevention...

Defibrillation threshold (DFT) testing during implantable cardioverter defibrillator (ICD) implantations is considered necessary for appropriate shock therapy and to measure the safety margin. However, the relationship between the DFT with modern era devices and the clinical outcome, including the total mortality is limited, which may lead to DFT testing itself being questioned. This study aimed to evaluate the relationship between the DFT and clinical outcome in ICD recipients.We enrolled 81 consecutive patients (66 males, aged 64...

BACKGROUND: Current algorithms and device morphology templates have been proposed in current Implantable Cardioverter-Defibrillators (ICDs) to minimize inappropriate therapies (ITS), but this has not been completely successful. AIM: Assess the impact of a deliberate strategy of using an atrial lead implant with standardized parameters; based on all current ICD discriminators and technologies, on the burden of ITS. METHOD: A retrospective single-centre analysis of 250 patients with either dual chamber (DR) ICDs or biventricular ICDs (CRTDs) over a (41...

BACKGROUND: Left ventricular (LV) ejection fraction (EF) has poor predictive value for ventricular tachyarrhythmia (VT). Other parameters such as LV dyssynchrony (LVD), and LV scar burden have also been individually associated with VT, but the interplay of these factors in the genesis of VT has not been explored. This retrospective study sought to evaluate the relationship between LVD and imaging characteristics of the myocardial substrate in predicting VT. METHODS: We identified 183 patients (150 men; mean age: 64 ± 14 years and mean LVEF: 23% ± 7%), who received an implantable cardioverter defibrillator (ICD) for primary prevention and who underwent a gated single-photon emission computed tomography (GSPECT) myocardial perfusion scan prior to ICD implantation...

In hypertrophic cardiomyopathy (HCM) patients with symptoms caused by left ventricular outflow tract obstruction (LVOTO), treatment options include negative inotropic drugs, myectomy, septal alcohol ablation and AV sequential pacing with or without an implantable cardioverter defibrillator (ICD). Pacing is rarely used in spite of its relative simplicity and promising results. In this review the current evidence of AV sequential pacing from observational, randomised studies and long and very long-term follow-up studies is given and put in the context of present guidelines recommendations...

Pietro Delise
Brugada syndrome is a possible cause of sudden cardiac death in subjects with characteristic ECG pattern (type 1 Brugada ECG pattern). Brugada ECG pattern is not infrequent in the general population and the challenge is to identify within a large population those patients who are really at risk. Unfortunately, this is a partially unresolved problem and this uncertainty determines an inhomogeneous behavior among doctors. Some of them overestimate the risk extensively indicating cardioverter-defibrillator implantation, others apply restrictive indications of guidelines, many are not able to decide without doubts...

Coronary venous dissection is a known complication of left ventricular lead placement during implantation of a cardiac resynchronization with defibrillator (CRT-D) system. A large-scale evaluation of the prevalence of coronary venous dissection and associated in-hospital clinical outcomes has not been performed. We sought to identify predictors of coronary venous dissection and evaluate subsequent in-hospital adverse events in those with the complication. We studied 140,991 first-time CRT-D recipients in the implantable cardioverter-defibrillator (ICD) Registry implanted between 2006 and 2011...

Anemia was shown to be associated with increased risk for adverse events in patients with heart failure (HF). However, there are limited data on the association between anemia and the risk for ventricular arrhythmias (VAs) in patients with an implantable cardioverter defibrillator (ICD). The present study population comprised 2,352 patients who were enrolled and prospectively followed up in the Israeli ICD Registry. The risk for a first appropriate ICD shock for VA was assessed by the presence of anemia, categorized at the lower tertile of hemoglobin distribution (≤12 g/dL [n = 753])...
