Hey man, i am a 17 year old who is slightly concerned about my heart palpitations. I have a very similar story, except mine started in march of 2022 and it was basically high bloos pressure and breathlessness. Since then ive visited my doctors, spend a few days in a hospital to do tests, everything was in the end good. However, what never went away were my heart palpitations. I basically every so often maybe like a few a day and sometimes i wont even feel them every day if im lucky but yes i do feelheart fluttering every day or every othe day. I would say it has to be anxiety and stress. Ever since the event that took place that night in march, i was basically in my bed about to go to sleep until i felt shortness of breath and heart fluttering, i was for the first time ever in my life, scared for my life. I told my dad and since he has Brugada Syndrome and i did tests on it back in 2018 which one test was positive none negative so there were chances i had it so that night my dad thought that that was it. Well, it wasnt. We meassured my blood pressure which came out to be 175/87. We rushed to the hospital and when i got there it all stopped, i basically went back to my normal self, and a few days later it all happend again. My constant BP every day til the end of march and a bit of april was always in about 140/70. And now in may it has all returned to normal with an average bp of 120/60ish. So basically at this point it has been 4 months since that scary event took place, i eat healthy, i consume less salt and stopped basically taking caffeine products. To this day we still dont know the exact cause of why my bp was high, but thank god its normal now. But as ive seen with many people, after a big scary event, your body will remember it for a little while and might give you stress and anxiety like to you and me. So here i am with heart palpitations most days. I try to not think of it but it is really hard not to. Its one of those things that you will remember for the rest of your life, and just having these heart palpitations, just thinking about "oh my heart is fluttering, oh ****" just really makes you anxious and stressful about it. I find it the best way to cope with it is to always remind myself that its all in the mind, just need to calm down and try to forget about it. Thank you for reading this message and i wish you a very healthy and long life.
