Hi, I'm a 23y old girl, and last year i have been diagnosed with arrhytmia and ventricular extrasystoles. I' ve been on rytmonorm for a couple of months now, and i felt better, although sometimes i had some palpitations. Since last week smth happend, because all of the sudden my heart started beating very fast( my normal heart beat is 50-60 bpm, and now it's 75-110 bpm). And it's like this the whole day long. I can't bring myself to relaxing, and even then my heart still beats to fast. I can feel it in my neck, i am short of breath and chest pains. I also have difficulties while moving(normal stuff like walking, or talking etc...). I do have a problem with stress and anxiety, but right now i'm not in a stressful situation. Is this normal? Is it just my anxiety? Or is it smth serious going on with my heart?
Thank you in advance!!
