I learned that when a person works with metal, his ECG will have lots of interference and be essentially unreadable. I had an experience with that yesterday and I was sure the machine was malfunctioning until I called in a co-worker for help. One look at the printout, and she asked the guy if he was a metal worker. He was.
What would happen if he would someday have a heart attack and need an ECG to see what’s going on with his heart? What are the alternative tests that can be performed on him to assess his cardiac function?
Also, where exactly is the metal located in his body? Embedded in the skin? In his lung tissues? If he would quit his job, would the problem gradually fade away, or is the metal in there forever?
