hi,
for the past six months i have been having these strong, irregular heartbeats, and i was recently diagnosed with sinus tachycardia. they could not find an explanation for the other irregularities (they did not show up on the holter). i was put on atenolol 25mg morning and night, and it's been working more or less, but i still have the irregular beats. sometimes, when i take a deep breath, my heart pounds really hard once before i exhale, or sometimes when i'm walking. i am on the skinny side, but not physically fit. and i still have these instances when my heart rate goes up to 120-130 and i get really panicky about it. i feel like sometimes the atenolol is working, but then i have these little bouts of anxiety. i'm really afraid that somethings wrong, even though i'm too young (19) and the echo and ecg was normal. i was just wondering if anyone has any idea what these irregular beats can be. right now i'm worried that while the atenolol is working (my heart rate was in the 100s before, and now it's around 80) it's causing something else. i know that i'm probably over sensitive to my heart, but i feel that the only way that i could become this sensitive is because i felt something weird and not right. i'm just really nervous about it.
also, has anyone experienced birth control causing palpitations? i had my blood tested and my potassium was normal, but i have been on the pill for as long as i've had the palpitations, and i'm convinced that it's correlated.
please someone give me some information if they have any idea. thank you!
