I am 25 Years old. from last two years, i am suffering from fast heart beat. my echo and ECG is normal. I consult with cardiologist who told me do Electronic Cardioversion. He did not take my any test and suggest me this treatment directly. Is this safe for me in early age without confirm it. My heartbeat fasts between 90 to 110per minutes.He told me to take treatment after one ony of visiting but i searched over internet that this producere reguires some procautions before 6-7 days of surgery. But cardioversion is checked by ECG but my ECG is nomal. Can anybody suggest me what i can do.
