When it comes to treating a heart attack, every second counts. Now, a device is being tested here in the United States, that would alert people before they get a heart attack.

It's called the Guardian. Developers said it lets patients know when there are changes in how their heart is functioning. The device comes in two parts; one is similar to a pacemaker. It's implanted in the chest and connected to the heart; it transmits data to a small, pager-like machine that patients can wear on their belt.

"It can detect any decrease in oxygen or suggestions of changes in the blood flow to the heart, which usually the cause of that is a heart attack,” said Dr. Hamid Taheri, an Interventional Cardiologist.

If and when something happens, the device vibrates and the pager beeps. If the yellow light comes on, it means there is a non-emergency event, but patients should see a doctor; if the light is red, it means the patient might be having a heart attack.

The device is available in Brazil, but could soon make it to the U.S.
