Student-invented cardiac patch could reduce heart attack fatalities The ResQ device continuously monitors the strength and timing of a heart's electrical activity and sends the data to a patient's caregiver and doctor By Wick Eisenberg / Published April 20, 2021 Jeff Kim, a master's student in the Department of Electrical and Computer Engineering at Johns Hopkins University's Whiting School of Engineering, wants to improve the survival rates of people who have a cardiac arrest while alone. This started for Kim, in 2016 when his uncle had a sudden and fatal heart attack while alone in his apartment. A couple of years later, Kim's grandmother also had a sudden cardiac arrest but was in a public location where onlookers saw what was happening and alerted first responders. She made a full recovery.
