Yes, I worked for a heart surgeon and a cardiology group for ove 30 years---you should not do anything to stress yourself out until you have further testing--which will be a stress test
and possibly a cardiac catheterization
....depending on WHAT was abnormal on the ekg......was it the rhythm or did it show a wave abnormality? it can also show if you had a previous heart attack
....not to scare you, I don't mean to, but I do want you to call your doctor and get sedatives to stay on so you don't stress until they test you... and forget working....take some days off and chill.....and no workouts of any kind--especially sex.....and if you fool around with sex drugs, or coke or any other recreational drug- YOU MUST TELL YOUR DOCTOR. They need that info because the drugs may have caused the irregularity..........sorry to be so blunt, but I don't want you to ignore the seriousness of this........age means nothing.........there were a lot of athletes that died of heart attacks at 16 and 17 because of congenital heart problems-- which mean they were born with problems....please take it easy and get some chill pills until at least you get your tests done.......and make sure you have a really good Cardiologist---check him out on the web.......
