Background For patients with a high risk of sudden cardiac death, despite the benefits of an implantable cardioverter ...

Despite advances in defibrillation technology, shock-refractory ventricular fibrillation remains common during out-of-hospital cardiac arrest. Double sequential external defibrillation (DSED; rapid ...

A new observational study suggests the position in which responders initially place the two defibrillator pads on the body may make a significant difference in returning spontaneous blood circulation ...

The Resynchronization–Defibrillation for Ambulatory Heart Failure Trial (RAFT) showed a greater benefit with respect to mortality at 5 years among patients who received cardiac-resynchronization ...

Researchers used an electrophysiological computer model of the heart's electrical circuits to examine the effect of the applied voltage field in multiple fibrillation-defibrillation scenarios. They ...

Global LEADR clinical trial meets safety and effectiveness objectives; results presented at Heart Rhythm 2024 and simultaneously published in Heart Rhythm DUBLIN and BOSTON, May 17, 2024 /PRNewswire/ ...

Adding to the Medtronic portfolio of catheter-based lead solutions, the novel OmniaSecure defibrillation lead allows for precise delivery and placement in the right ventricle Heart Rhythm 2025: ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...

Joshua Lupton, M.D., has no memory of his own cardiac arrest in 2016. He only knows that first responders resuscitated his heart with a shock from a defibrillator, ultimately leading to his complete ...
