I am 22 years old. My resting heart rate as for now is 90bpm, it drops more when I go to sleep. I have an anxiety disorder about illnesses. I have had this issue for years, and over the years I’ve undergone over 30 EKG’s, over 20 ECHODIAGRAMS, 2 Stress tests, 2 holter monitors, and all the time they said that I had no issues with my heart, I’ve had over 10 full blood works, had an chest X Ray, head CT, mulitple ENT visits, I can’t even remember what else, my life has gone through worrying about what illness do I have while not being able to diagnose ANY. So as I was doing the worst thing that I could do, I was reading symptoms online AGAIN (this is how my health anxiety started at 12) and I found out that I may have hyperthyroidism, so today I immediately went and had my hormones checked, and for the procedure they had to measure my heart rate, it was a whooping 160, the man there was like oh I think the machine isn’t working, as I stay still I do not show my emotions, guess what my hormonal levels were good too, what else is there? I am tired of living this way, this has drained me beyond limits, I am 22 and living in worries of instant death all the time, my heart rate is constantly high though. I remember when I was 14 I kept wondering whether I'll be alive to be 18, now I am 22 and I am wondering whether I'll reach the 30's. The cycle never ends, this fast heart rate has made me insane, while cardiologists kept telling me that my heart had no issues after so many examinations, I've even been to ER twice. It sucks to live this way and not knowing what is wrong with you
Anyone?
sorry you are going through this. Millions of people suffer from anxiety including myself, A former nurse.
One of the most common symptoms is a racing heart rate. This happens because when you are anxious, adrenaline is released which causes the heart rate to speed up.
this has been going on since people walked the earth. that’s because when you are anxious your brain thinks you are in trouble and it prepares you by speeding up your heart rate to get oxygen to every part of your body.
you have had quite a few tests done. Sounds like you are very healthy but the anxiety and fear are taking you over.
What you need to do is learn how to manage the fear and anxiety so you can go on with your life and enjoy it!
It took me many years to finally come to the realization that I am healthy and I need to get control back. All those years were wasted with fear and anxiety for no reason. I would hate to have this happen to you.
Fast heart rate will not hurt you. you have been worrying from age 12 until now and nothing bad has happened.
that is 10 years of your life that you cannot get back. You could’ve been enjoying those days. Now it’s time to get tough with yourself like I had to do and be determined to enjoy each day. if you don’t do this, you will be 70 years old and still doing this wondering if you’ll make it to 80! Believe me, it’s not worth it!
I now have the attitude that I am not going to worry. I’m not going to worry until I absolutely have to. In the meantime I’m going to enjoy my life and do things that make me smile and happy. do things that make you happy and smile.
You are fine! Be a fighter for yourself and be determined to be positive and not let fear ruin your life!
There are some great meditations on YouTube for anxiety, fear, sleep, etc. I especially like a short one for proper breathing that truly brings down the heart rate and made me feel so much more relaxed! Search for something called stop panic attacks now and then scroll to the one called don’t panic. It’s in black letters. She guide you through the proper breathing and at the end you feel much better! Take care of yourself! You are young. You are healthy. counseling can really help you manage anxiety. please stay off of Google because it doesn’t pertain to your individual situation. It just perpetuates the negative thinking. we only get one time around so make it your best! Take care 
Thank you so much <3 . Isn’t it crazy how after all those years and after all those tests I still worry that my heart is not healthy and I can die any moment from a heart attack, my last cardiologist (which is considered the best around here) told me that I have more chances of dying from a car hitting me just as I go outside the clinic than from a heart attack. It’s really crazy isn’t it.
Hey there, I’m a 22 year old female and I’ve had this same issue for a while now and tried all sorts of anxiety medicines but my body is sensitive to medication so i wasn’t able to continue with any.
Recently I got off all medicine and realized that every single time I stand up or even move my heart rate sky rockets to 120-140 bpm easily and if i try to exercise my heart rate easily goes up to 170-190 bpm.
I went to my doctor and they did an EKG of my heart as I stood up and it was all over the place but my EKG laying down was completely fine. Therefore I was diagnosed with POTS (postural orthostatic tachycardia syndrome) where pretty much my body doesn’t understand gravity and all my blood pulls to my feet when i stand up and my heart pumps faster and harder to try to get blood back up to my brain.
i was diagnosed with anxiety as far back as i remember and POTS is usually misdiagnosed as anxiety to where my doctor actually apologized to me that we thought it was anxiety this whole time.
I hope this helps and you should look up POTS and see if you have similar symptoms if so you should see your doctor to get diagnosed.
I agree with you 100%. My anxiety started after a caffiene induced attack and it went down hill from there. I started feeling imbalanced and started having mini attacks because of the fear. It took 8 months and many tests for me to accept. I am a fighter now, and i’ll make sure to continue life as intended. Like you said, it’s not worth living in fear. Life is short already.
