Hi I want to ask if heart palpitations can be felt like irregular heart beat? I have been on several cardiologists and everything is fine according to the three doctors I have visited. They have done ekg and echocardiogram. They think that I have anxiety problems. It is ture that the problem started during a very stressful period for me but I am worried that sometimes for a very short period of time I feel like my heart is beating not regular. Maybe it s ectopic beats because they happen during a panic attacks and sometimes after consumption of coffee or sweet things. Noting is seen on the ekg but I have this sensations rarely and for a very short period of time. Also during a panic attack my heart rate is about 113 beats it is high but really not that much for a panic attack. The cardiologists that I have seen are positive that my heart is healthy and I don t have arrythmia. They told me that ectopic heartbeats even though they can be scary are harmless. I am not sure if what I feel sometimes are ectopic heartbeats and it is difficult to check with holter because I can go weeks without having such sensations. I am also with hypothyroidism but I am on medication and my test results are fine. And I have been checked for anemia. My results are at the lower end of the reference range but still in range so it shouldn t be due to this. Since I have hypothyroidism my ferritin and hemoglobin levels are a bit low still in the range but in the low end and my GP prescribed me iron but said that it can t be due to this because the imbalance is small.
