There's a check engine light to show you if something is wrong with your vehicle. But what about when there's a problem with your heart?

"In cardiology what we're starting to see are devices that can just start looking at your heart rate," Dr. Sam Jones, with Chattanooga Heart Institute, said.

Heart disease is the leading cause of death for both men and women across the country.

Dr. Jones said it's important for patients to take an active role in their health and that means not smoking, watching your weight and knowing your numbers for things like blood pressure and cholesterol.

"Genetics may play a part of it, but a lot of it is the things we're doing to ourselves," Jones said.

Steve Pearson has constantly struggled with his weight so he turned to running. Pearson was training for a marathon about 3 years ago when he found himself in the ER suffering from extreme pain and exhaustion.

"They discovered I was having a gall bladder attack, but at the same time they figured I was in Afib," Pearson, who is a heart disease survivor, said. 

Pearson went on medication, but he also turned to wearable technology to help him monitor his heart.

"The thing about this smartwatch and technology, if I feel funny or tired or in Afib I don't have to check in with the doctor and get an EKG, I can just hold my watch for a few seconds and it will tell me whether I'm in rhythm or Afib," Pearson added. 

"There's been an explosion in technology, wearable technology in healthcare, it turns out we can probably monitor just about everything," Jones said.

Pearson said he constantly monitors his device. It gives him peace of mind.

"So you can track those things and it brings comfort to know that I'm okay this is okay," Pearson said.

Doctors say there is no doubt that mobile cardiology and smart devices are gaining momentum, but they stress this technology doesn't replace a visit to see your physician.
