Slow ventricular tachycardia (VT) in patients with devices such as an implantable cardioverter - defibrillator (ICD) is more common than in the rest of the population. The incidence in elderly patients with an ICD remains largely unknown. In younger patients, slow VT is generally asymptomatic or associated with limited clinical relevance. It may be efficiently and safely terminated by anti-tachycardia pacing. We present a case of slow VT in a 91-year-old man with ICD with type 1 acute respiratory failure and drowsiness...

AIM: An increasing number of failing automated external defibrillators (AEDs) is reported: AEDs not giving a shock or other malfunction. We assessed to what extent AEDs are 'failing' and whether this had a device-related or operator-related cause. METHODS: We studied analysis periods from AEDs used between January 2012 and December 2014. For each analysis period we assessed the correctness of the (no)-shock advice (sensitivity/specificity) and reasons for an incorrect (no)-shock advice...

Screening tests conducted at rest may be inadequate for the prediction of the T-wave oversensing (TWOS) in subcutaneous implantable cardioverter defibrillator (S-ICD) candidates with Brugada syndrome (BrS) because of the dynamic nature of electrocardiogram (ECG) morphology. We evaluated the utility of ECG screening during drug challenge (DC) for prediction of TWOS in BrS patients implanted with an S-ICD. The study enrolled 6 consecutive BrS patients implanted with an S-ICD. In addition to baseline ECG screening, pre-implant screening during DC using a sodium channel blocker was performed in all patients...

INTRODUCTION AND OBJECTIVES: In recent years, public access defibrillation programs have exponentially increased the availability of automatic external defibrillators (AED) in public spaces but there are no data on their performance in our setting. We conducted a descriptive analysis of the performance of AED since the launch of a public defibrillation program in our region. METHODS: A retrospective analysis was conducted of electrocardiographic tracings and the performance of AED in a public defibrillation program from June 2011 to June 2015 in the province of Girona, Spain...

Use of cardiac implantable devices and catheter ablation is steadily increasing in Western countries following the positive results of clinical trials. Despite the advances in scientific knowledge, tools development, and techniques improvement we still have some grey area in the field of electrical therapies for the heart. In particular, several reports highlighted differences both in medical behaviour and procedural outcomes between female and male candidates. Women are referred later for catheter ablation of supraventricular arrhythmias, especially atrial fibrillation, leading to suboptimal results...

Implantable cardioverter-defibrillator (ICD) is the gold standard therapy for the prevention of sudden cardiac death. Nevertheless, ICD placement in the paediatric population is still limited because of several technical difficulties. Several implantation techniques have been proposed but experience in infants with very low weight and less than 6 months is very limited. We herein describe a case of a minimally invasive ICD epicardial implantation in a 4-month-old infant weighing 5 kg. A diagnosis of arrhythmic cardiomyopathy with left ventricular non-compaction disease with ventricular tachycardia storms, QT prolongation and Wolff-Parkinson-White pattern was made...

BACKGROUND: Information regarding suitability for subcutaneous defibrillator (sICD) implantation in tetralogy of Fallot (ToF) and systemic right ventricle is scarce and needs to be further explored. The main objective of our study was to determine the proportion of patients with ToF and systemic right ventricle eligible for sICD with both, standard and right-sided screening methods. Secondary objectives were: (i) to study sICD eligibility specifically in patients at high risk of sudden cardiac death, (ii) to identify independent predictors for sICD eligibility, and (iii) to compare the proportion of eligible patients in a nonselected ICD population...

Mark Josephson dedicated his career to the prevention of premature sudden cardiac death (SCD). Toward that goal, he was an early adopter of the implantable cardioverter defibrillator (ICD) and indefatigable advocate for better ICD technology,[1] both as a clinical tool and as living laboratory to study SCD in ambulatory patients. With characteristic intellectual integrity and analytical rigour, he sought an honest and balanced appraisal of the life-saving benefits and serious complications of this unique therapy...

BACKGROUND: Among patients with implantable defibrillators (ICD), use of remote patient monitoring (RPM) is associated with lower risk of death and rehospitalization. Standard ICD RPM can be supplemented with weight and blood pressure data. It is not known whether standard RPM plus routine weight and blood pressure transmission (RPM+) is associated with better outcomes. METHODS AND RESULTS: RPM+ patients (n=4106) were compared with patients who only transmitted standard ICD RPM data (n=14 183)...

Optogenetics provides a tool for controlling the electrical activity of excitable cells by means of the interaction of light with light-gated ion channels. Despite the fact that optogenetics has been intensively utilized in the neurosciences, it has been more rarely employed as an instrument for studying cardiac pathophysiology. However, the advantages of optical approaches to perturb cardiac electrical activity are numerous, especially when the spatio-temporal qualities of light are utterly exploited. Here, we review the main breakthroughs employing optogenetics to perturb cardiac pathophysiology and attempt a comparison of methods and procedures that have employed optogenetics in the heart...

BACKGROUND: Low-energy anti-fibrillation pacing (LEAP) has been suggested as an alternative treatment to symptomatic fibrillation patients. It significantly lowers the energy required compared with standard one-shock defibrillation. OBJECTIVE: In this study, we investigated the mechanism of arrhythmia termination by LEAP and systematically analyzed the influence of shock period and timing on the success rate of LEAP. METHODS: We induced atrial and ventricular fibrillation in isolated canine hearts and applied LEAP and standard one-shock defibrillation to terminate the arrhythmia...

AbstractChagas disease (CD), with associated conduction abnormalities, is a common indication for pacemaker implantation in Latin America. The prevalence of CD in Latin American immigrants with pacemakers residing in the United States has never been studied. This single-center cross-sectional study included pacemaker patients who were aged 18 years or more with a previous residence in Latin America for at least 6 months. Patients with an implantable cardioverter-defibrillator, cardiac resynchronization therapy, or iatrogenic and/or congenital heart block were excluded...
