Several weeks ago i was working and had 3 episodes in a short period of time that felt like electrical shock in my chest. The last on got my heart to racing so they took me to tje ER. Once i was there, ekg blood work and xray checked out fine. I have been experiencing chect discomfort(no particular point) as well as left arm and shoulder pain. About a week ago I was in Walmart and had another episode. I ended up in ER yet again and everything checked out normal. Since I have had a stress test and echocardiogram that came back normal. I have been wearing an event monitor that goes of many times a day. I continue to have moderate chest discomfort and arm pain. My doc recieved one reading that showed ventrical tachecardia. He suggest having a catheter ablasion. I was amazed that he suggested a procedure before meds..(this was the first time he saw me) ...should i seek a second opinion? Do i need this procedure?
