Objectives: To determine the effect of physiologic catecholamine concentrations on the defibrillation threshold (DFT) in patients with implanted cardioverter defibrillators. Background: DFT is the ...

Stockholm, Sweden - Early testing of an implantable cardioverter-defibrillator (ICD) featuring a totally subcutaneous lead system suggests the device can terminate ventricular tachyarrhythmias using ...

Defibrillation testing during implantation of cardioverter–defibrillators is controversial because of potential safety concerns and a lack of evidence for the effectiveness of the procedure. New data ...

A small-diameter, defibrillation lead that can be delivered through existing commercially available catheters for targeted placement is durable and safe, with no incidence of fractures at 1 year, the ...

BOSTON -- A novel small-diameter lead wire had a high level of success for delivery of implantable cardioverter-defibrillator (ICD) shocks and low complications, the LEADR pivotal trial showed. The ...
