Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
I know it seems super frustrating right now, but you are moving forward, just in smaller steps than you want. At least you've got concerned, pro-active docs on your side ... sometimes that can make all the difference!
What they concluded was that there was no strange arrhythmia going on but that my heart did occasionally skip a beat or prematurely beat and also my heart tends to overreact to any exercise. When I was at the stress test my heart was at 120 before I took a single step on the treadmill and made it up to 180 at the top level of incline. What my doctor explained was that sometimes after you have a big traumatic incident in your health, your heart can take awhile (even years) to get back to normal behavior. They aren't really sure why, but that it wasn't anything dangerous (in my case). The problem is also exacerbated by the fact that I have very low blood pressure and so just standing up will cause my heart to go into overdrive to get blood up to my head. I've been told to add more salt to my diet, stay hydrated, and also try a magnesium supplement which he said some people say really makes a difference with the palpitations.
I hope your test went well and that they help you start to feel better! It's so frustrating to feel like you're being limited and held back by your health still, but there is definitely peace of mind in getting the tests done and hopefully knowing that nothing dangerous is happening.
