Summary

This study tested a new type of wire (lead) for implantable heart devices that deliver shocks to stop dangerous fast heart rhythms. Researchers checked how safe and effective the lead was in 998 people who needed a defibrillator or heart failure device. The lead was placed in a specific spot in the heart to see if it could reliably stop abnormal rhythms.
