Hello everyone! I'm new to this forum. I am a relatively healthy 25 year old and I've been dealing with some health issues since February 2016. I've been having a hard time getting a diagnosis so I just wanted to run some of my symptoms to you all to see if this could actually be a mild form of POTS or just severe anxiety and stress? I know the mind can be a pretty powerful thing!
Back in Feb. I had about two really bad panic attacks where my heart rate reached up to 170-180 bpm. For quite some time I was literally too scared to move or do anything because I constantly felt my heart beating. I would say up until Aug is when the actually "panic attacks" stopped but I was still having really bad anxiety. My resting HR would sometimes be high, but I noticed that when I would try to do anything around the house or even standing up shot my HR up high. Sometimes it got up to 145. But at the same time I was really stressed out. I went to a cardiologist and had a battery of test ran.
EKGS (multiple) - NORMAL
Echocardiogram - NORMAL
Blood test - NORMAL
Stress test - NORMAL but my resting HR was 130 and then my maximum HR on the treadmill after 7 mins was 184.
Chest x-rays - NORMAL
CT of chest - NORMAL
Tilt table test - I did pass out but my doc said it was not POTS, but a cardio inhibitory form of NCS. After about 10 mins I starts having pre-syncope symptoms and my doctor said I blacked out and my HR went down to 45. He said that my BP was fine and didn't crash. He said that the tilt table test is designed to make people pass out and if I never passed out before on my own (which I haven't) not to worry.
He told me that it is just stress and anxiety and that my heart is perfectly fine. My doc prescribed me 25 mg of atenolol for the high heart rate. He also said that it would help my physical symptoms of anxiety. I didn't take it for 3 months because I was worried it would drop my BP to a dangerous level even though I had normal blood pressure. I eventually started the medicine but I only took half. I am currently still on atenolol but it only helps a little bit. But here's a little bit of my symptoms: constant chest tightness, soreness, pressure, upper back and neck pain, rapid heart rate with minimal exertion cleaning the house: 85-120 bpm, showering: 100-130 bpm, walking up the stairs 120-140 bpm, constant fatigue, headaches, weird vision changes, feeling of adrenaline and head rush while standing. My heart rate does not always increase drastically when standing but 7 times out of 10 it does. My resting heart rate is normally around 65-80 bpm. 85-95 bpm when I'm anxious or stressed by something. Is this a mild form of POTS or anxiety?
