User :   Hi. I'm 30y and a few days ago couple of hours after excersising i felt a sharp pain in my chest. The next evening i went to work and i asked a collegue of mine to do me an ECG(i'm a nurse). When i showed it to a cardiologist he asked whos ECG it was and he wouldn't beleive it was mine. I said it was mine but he said its impossible, this shows a heart attack, It can't be yours. It had T waves turned upside down and i also had a sinus arrythimia. i repeaded the ECG and it was normal. Only the sinus arrythmia. He said you must have copied it from the machines menory by accident but when he checked there was nothing in the memory and he aslo said that the wires were correctly placed when i asked if that might have done the trick. Anyway he gave me an echo and said there was nothing wrong with me. The thing is i'm afraid. I have a history with bradycardia and when i had a 24 h ambulatory it showed that my pulse droped down to 38 when asllep. It's not that i don't trust my doctor but 1. i have ms and been on Tysabri for a year now so i don't know if there is any relevance and 2. if the wires were placed correctly and the memory of the cardiografer was empty how was that ECG printed with an MI all over it? Now my question is " Do you think that there is a possibility that i did have the heart attack and after so many hours it wasn't visible on my ECG? " I still occasionally feel my chest a bit heavy but i don't know if its my mind playing tricks on me. " Is the echo a good way to clarify if there was an MI or not?" Thanks for your attention.
Doctor :   Hi,
User :   Hello
User :   Theodora. n2mu
Doctor :   Let me read your query for few minutes to be able to have a good discussion here
Doctor :   there is no relation of Tysabri with your problem
Doctor :   Well machine mistakes ,may i know which lead showed the t wave inversion ? can be expected
Doctor :   **
Well machine mistakes can be expected ,may i know which lead showed the t wave inversion ? can be expected
User :   if i'm not mistaken it was v4, v5, v6
Doctor :   ok, if seen in three leads then machine mistake is least expected
User :   how come it wasn't visible when i had another ECG 12-14 hours later
Doctor :   as time elapses the finding too disappear
User :   and the echo wouldn't that show something?
Doctor :   i would recommend a treadmill test better than a n echo in this case
User :   i work out. I go an the treadmill for 25 min and walk over 2km. Is the test harder or different?
Doctor :   it is different it does pick up if there is any impending caronory risk involved
Doctor :   in 2 d echo you can get to know the mechanics of the heart rather than vascularization
User :   ok i'll ask my doctor if i can have a treadmill test. Whats the difference with stress test?
Doctor :   its the same
User :   oh. I'm sorry i'm a scrub nurse and i'm not familiar with all this.
User :   so perhaps i should take it seriously and get checked? You beleive it was an MI with all the facts stated?
Doctor :   30 year old , its less likely
Doctor :   hence second line investigations are advised
User :   ok. Thank you very much for your advice and for your time. Have a good night and greedings from Cyprus.
Doctor :   you are welcome
Doctor :   Thanks for consulting me
Doctor :   kindly provide your feedback
Doctor :   bye for now
Doctor :   Take care
