Hi @jimcullen and welcome to Mayo Clinic Connect. Connect is not made up of Mayo physicians, but rather community members and patients just like you and your wife. I would definitely call the physician's office that ordered the ECG so that you can talk with the medical team and determine if they think she needs to see a specialist.

@truus1106, @danab, @predictable and @oldkarl have also participated in this conversation and have had experiences of their own.

After you received the results did anyone call you to talk about the report? Is she currently having any symptoms.

@jimcullen Hi and Welcome to connect. I've had many 12 lead ECGs and the results are usually handed to the Doctor immediately. But based on the information given I can't say if it's a urgent situation but I can let you know that most technicians giving the test are a little knowledgeable about what is urgent and or can wait to be evaluated by a specialist . I thru my experience when I would ask how it looks would get the response "well I'm not allowed to say as I'm not a doctor but if I run out of here urgently might give you a clue. Even EMTs are trained enough to recognize life threatening verses is not an issue or can wait for a follow-up at a later time. I would have some confidence that if the Doctor hasn't either said anything yet or has not called for a follow-up it's probally not urgent.
Now as for the passing out I would tho follow-up and maybe seek an appointment with a cardiologist. Never hurts to know for sure. I hope that sets your mind at ease. Please let's us know how things turn n out and I went thru years of Heart issues so if I can help with any questions please let me know.
Have a Blessed Day
