Hi Soapopera123, I like to start by defining what sounds like a word that sounds serious. Tachycardia is a fancy word for increased heart rate. It's used anytime your heart rate exceeds what they call normal or about 100. I had a condition named Ventricular Tachycardia which is a abnormally high heart rate of the lower part of the heart. It would reach heart rates at times over 200.
So you mentioned what sounds like they put a loop recorder in to monitor your heart. This will be a blessing if the reason for your elevated heart rate is determined and how high it gets. So I defiantly would not worry if its like in the low hundreds. I have known people, including myself that can have normal heartrate in the 100-120 range. So my I ask how high they have told you yours get? The only time I ever needed further treatment is when mine got high enough that I was out of breath also. Kind of like when you run a 100 yard dash without taking a step. So I hope that my set your mind at ease a bit. Now if the heart rate is more like in the 150-200 range then I would definitely suggest seeing a cardiologist.
Let me know if I can help further.
