I did my TMT on 16th of April and after that on 18th April I was detected covid positive. That time I did as I was having acid reflux issues. I got covid negative on 29th April after home isolation. After that I was having problem of rapid heartbeat specially while climbing stairs etc. So I visited a cardio who did ecg and echo and it was all fine. He told it was because of anxiety. Now the heartbeat is mostly normal ( resting heart rate 60-70 after waking in the morning). But sometimes while walking i feel slight chest pain (especially when I walk more than 20-25 minutes). Do I need to repeat TMT again? Is it possible that covid infection can cause plaque in arteries even when the first TMT came out as fine ? Kindly suggest.
