Not what you want to hear

Went to my heart check up and after they listened to my heart and did a EKG. The nurse doing the test had a look on her face and said I'll be right back. A few minutes late she returns with the doctor and he reviews the results.

Is everything ok

Well I'm not a big fan of what I'm seeing so we're going to do few more test. Can you stay a while longer.....

Update. They think I've had a silent heart attack recently.
