Wrestling icon Hulk Hogan had a big medical scare this week after doctors thought they found an abnormality with his heart.

Hogan is set to undergo another back surgery in the coming weeks and has been going through the usual battery of pre-op medical tests to insure he's healthy enough to go under the knife. According to TMZ.com, doctors discovered a problem with his Electrocardiography (EKG), which monitors a patient's heart function.

Sources close to Hulk tell TMZ.com that Hogan was sent to a cardiovascular specialist in Florida for further testing. After another extensive round of medical tests, doctors were able to medically clear Hulk who was understandably "very worried" during the whole process.

Hogan's heart has been deemed healthy and he's scheduled to undergo back surgery soon.
