A needle in the neck to shock the heart back to life?
Disease control CompletedThis trial tests whether injecting a local anesthetic into a nerve cluster in the neck—called a stellate ganglion block—can help stop dangerous heart rhythms in people who suffer a cardiac arrest outside a hospital. The study includes adults whose heart stops with a shockable rhy…

Wearable patch shocks heart back to rhythm in lab study
Disease control CompletedThis study tested a wearable defibrillator patch (the Jewel) in 18 adults who were already scheduled for a heart procedure. The patch was used to deliver a shock to stop dangerous heart rhythms that could lead to sudden cardiac arrest. The goal was to see how often the patch coul…

New catheter maps Heart's electrical chaos in real time
Knowledge-focused CompletedThis study tested a new catheter designed to measure the heart's electrical signals in people with irregular heartbeats (atrial fibrillation, ventricular fibrillation, or junctional tachycardia). Researchers enrolled 42 adults to see if the device could better identify abnormal e…

Double shock strategy for cardiac arrest put to the test in pilot trial
Knowledge-focused CompletedThis pilot study tested whether using two defibrillators early, instead of one, is feasible and safe for people whose hearts stop outside a hospital and don't respond to the first shock. Researchers enrolled 40 adults with a shockable heart rhythm. The goal was to see if emergenc…
