I am 26 years old, and I have been having weird palpitations for a couple of years now. I have even been to a cardiologist (about 1.5 years ago), and had a sonogram of my heart, as well as wearing a 24 hour holt monitor. The sonogram show that my heart was structually fine. And the holt monitor of course didn t pick up anything during that 24 hours. I am so worried that there is something seriously wrong with me. It happens so sporadically, and there is really no rhyme or reason other than when it happens it scares the crap out of me, and I always check my pulse immediately, and everytime my pulse is fine. Any comments or suggestions? I don t know what to do. I m so worried that there may be something wrong with me and I am not getting treated. All comments are so very helpful. Thank you all! And yes, unfortunately, I have been diagnosed with anxiety and panic attacks, but the weird thing about it is I havn t had a panic attack in almost 2 years! Anxiety...sure, but I am usually just standing still, or sitting and it just goes bananas on me.
