I was experiencing some palpitations during fast walk and during usage of stairs. My heartbeat is also irregular due to anxiety. I got my echocardiography done and doctor said it's all right but heart rate was 109 during the test. Later pft was also performed which was also good. Later on tmt was to be performed but the doctor said my heart rate is 134 so he didn't do the tmt test. Though I coughed high and got up fast and at that time his computer recorded the ecg. I got my ecg done very next day and it was alright then. My lipid levels are total cholesterol is below 200, ldl is 133, hdl is 48, triglycerides are normal. Doctor gave me novastat gold in afternoon and nebifid 5 at night. After using these medicine just for 2 days my palpitations are gone and I feel good sometimes I also feel pain in different areas of chest (both sides, mostly left), as if someone has pinched a pin on that area for just a second. The doctor has advised coronary angiography but has said that heart is ok. My sleep and meals are irregular. Question is what could be the reason behind ok echocardiogram and advice of doctor to do coronary angiography? Medicines are for 15. Days only.
