So I'm new here and I want to find out if anyone ever had an episode of afib/svt on lexapro? I was on it for 8 years of my life and it was great! Last two years were horrible. I was depressed and never was before I gained 20lbs didn't want to go to work had issues sleeping. I was in the treadmill first episode had like two hard beats then racing heart then it was gone. I didn't go to er I just thought it was really scary but by passed it. I ended up getting off lexapro 2 years later and the withdrawals were hell. I couldn't take it. So I went back on lexapro 18 days into it ant almost two years to the date I had that same episode again I called 911 my guns and said it was just my anxiety I said I know the difference and this isn't regular racing heart it was Chaotic it started with a thump then double thump took off racing like I was running but was sitting still. It lasted maybe 10-15min and just poof just stopped and sent back to normal. Sorry long post.
