Introduction Subcutaneous implantable cardioverter-defibrillators (S-ICD) provide an alternative to traditional transvenous implantable cardioverter-defibrillators (TV-ICD) and avoid complications associated with intravascular access and leads. They are highly effective in detecting and treating ventricular arrhythmias, with comparable inappropriate shock rates. Use of S-ICD is anticipated to i...

Association of Long vs StandardDetection Intervals for Implantable Cardioverter-Defibrillators WithHospitalizations and Costs The roleof implantable cardioverter-defibrillators (ICDs) in reducing sudden and overall mortality is established.1 Recently, an ICD programming strategy that allows delayed detection of arrhythmiaswas shown to reduceunnecessary and inappropriate therapies.2,3 In this ex...

Thrombosis of the superior vena cava is not frequent, but its appearance makes difficult the way for the implantation of pacemakers and defibrillators. There are alternatives when endovascular and epicardium vias cannot be used. However, some implantations of catheters of defibrillators via transatrial through minimal thoracotomy with good results at long-term and with an adequate threshold of ...

A lthough medical factors predisposing to atrial fibrillation (AF) are well described, whether and how psychosocial factors influence the development of AF remains a nearly unexamined area. In this respect, AF lags far behind other cardiovascular conditions, such as coronary artery disease and ventricular arrhythmia, in which relationships between psychosocial factors and cardiac disease have b...

BACKGROUND Implantable transvenous cardioverter-defibrillators offer a significant opportunity to decrease procedural morbidity and medical costs in the care of patients with life-threatening ventricular arrhythmias who otherwise would have required a sternotomy or thoracotomy for device insertion. The purpose of this study was to examine prospectively the safety, efficacy, and limitations asso...

I am concerned about the implications of the Editorial by Drs. Lown and Axelrod which appeared in the October 1972 issue of Circulation. Although the authors rightfully point out the numerous technical problems still to be overcome in the development of such defibrillators, their conclusions in the last three paragraphs indicate a heavy bias in favor of "practical research." Although Dr. Lown h...
