Students’ Heart-Shocking ‘Shirt’ May Save Lives When Paramedics Are Not Nearby

Johns Hopkins biomedical engineering students have designed a lightweight, easy-to-conceal shirt-like garment to deliver life-saving shocks to patients experiencing serious heart problems. The students say their design improves upon a wearable defibrillator system that is already in use. Their design changes, the students say, should help persuade patients at risk for sudden cardiac arrest to wear the system around the clock.

Researchers Aim to Use Light—Not Electric Jolts—to Restore Healthy Heartbeats

When a beating heart slips into an irregular, life-threatening rhythm, the treatment is well known: deliver a burst of electric current from a pacemaker or defibrillator. But because the electricity itself can cause pain, tissue damage and other serious side-effects, a Johns Hopkins-led research team wants to replace these jolts with a kinder, gentler remedy: light. In a paper published Aug. 28 in the online journal Nature Communications, five biomedical engineers from Johns Hopkins and Stony Brook universities described their plan to use biological lab data and an intricate computer model to devise a better way to heal ailing hearts.
