I had tachycardia 2 months ago. I visited the doctor he gave me medicines and after 1 month it got normal .But doctor told that I should continue the medicines so since now I am taking medicines. But now I get pain in chest and sometimes in heart but not too bad I think it's just normal pain not so painful. But it's not going at all. I am having this every 2 days. And now I am feeling bad for this is it life threatening condition. What should I do. Sometimes I think that it's normal but sometimes I think it is not. And that pain occurs every 2 days not fixed whether it is on nights or days but it comes every 2 days. So help me what should I do. My heart rate at that Time was 129 BPM. LVEF was 66%.And had mild Mr. and mild TR. ERVSP was 20 mmHG. INTACT IAS and IVS.
