Every 40 seconds, someone in the U.S. dies from a heart attack. The most common cause of death in the US is heart disease, which is a group of underlying conditions that can result in a heart attack.
To address this, Khalil and his team developed a chip that uses artificial intelligence and advanced mathematical models to analyze electrocardiograms (ECGs) - graphs of the heart’s electrical activity - and detect heart attacks in real time.
The resulting technology is 92.4 % accurate, outperforming many existing methods. It is also small and energy-efficient enough to be built into wearable devices.
We wanted to be able to implement this in a way that is real. This is portable hardware that can be in wearable or monitoring devices. This method will save lives because we can monitor the heart in real time.

Mohaidat, from Irbid, Jordan, focused on developing the artificial neural network, while Md. Rahat Kader Khan handled the device’s software. Khan, a second-year graduate student in computer engineering from Dhaka, Bangladesh, said what makes the Khalil lab unique is its comprehensive approach, covering every aspect of the technologies they aim to create.
Some labs only focus on the software part, and they do not think about the hardware that is needed, but in our lab, we focus on the whole product. Each of us has a responsibility, but we work together. That is how we optimize the whole system, by focusing on the overall architecture.

Current methods for detecting heart attacks often require a hospital visit. Patients typically need an ECG or blood test to confirm the diagnosis, which takes time they may not have.
The researchers believe that wearable devices, such as phones or smartwatches, could speed up diagnosis and help patients receive treatment sooner.
Khalil said, “When a patient is having a heart attack, the sooner you can treat them, the less likely they are to have permanent damage. There is a huge time-sensitive element to heart attacks.”
Khalil and his team are continuing to refine the technology and believe it could have broader applications in healthcare.
Khalil said, “We want to be able to predict or identify many problems using technology like this. Whether that is heart attacks or seizures or dementia. The detection of a disease or condition depends on the disease itself, but we are working to find faster, more efficient ways of doing that.”
