[|Human|] Hello my name is mary and im 23 yrs old,I recently went to the ER for heart palpitations and small chest tightening,They gave me a chest X-ray,EKG,urine and blood tests which all came back normal.The only problem was that my heart was beating fast.They gave me metoprolol 25 mg once a day,it seems to be working but im very tired and cant see a cardiologist until 2 1/2 weeks from now.I have felt my heart flutter before but not enough to scare me but after babysitting alot of kids and one getting hurt thats when i started noticing the flutter turned into a thump.I personaly think i may have anxiety and that might be what has to do with it.Some ppl say it may even be antacid but im not sure,I guess my question is what do you think,whats your opinion?
[|AI|]  Hi, Increased heart rate and palpitations can have a lot of causes. It can be normal sinus tachycardia due to anxiety or stress, or it could be abnormal supra ventricular tachycardia. For the diagnosis, you need to do ECG at the time of palpitation and tachycardia. If the duration of palpitations are short enough to reach a nearby hospital, we put a 24-hour ECG monitoring (Holder Monitor). You also need to do a 2D Echo and thyroid function test to see for any associated abnormality if any. It will be really helpful if you could send me your ECG and other reports. Hope I have answered your query. Let me know if I can assist you further.
