I am not very knowledgable when it comes to understanding EKG strips but I hope someone can help. I was listening to my scanner at home today and I heard one of the EMS squads en route to the hospital with a man that had been at a MD's office and said apparently he was having an MI. It said on the monitor he was showing tombstones. What does that mean? I just knew it didn't sound good. Anyone have a clue?
