Irregular heartbeats with Zoloft?

Hi all,
I'm new here, although I'm usually on the fibromyalgia and anxiety forums.
I'm 58 and was started on sertraline about 3 and 1/2 months ago. Being very sensitive to meds, it took me about a month to get up to 50mgs. That didn't work out, as it gave me 3 weeks of bad diarrhea (on top of my usual IBS stuff). I'm presently at 25 mg, and doing okay. But I've developed some pretty bad bouts of PVCs (irregular heartbeats). My body is weird, and I know I can get PVCs from a number of different things. But I'm wondering if now they are coming from the sertraline. My brother said he got alot of palpitations on it at first, but they went away. I've been on varying doses of it for 3 and 1/2 months, and these palpitations seemed to worsen about 6 weeks after I started the drug.

I've recently had a stress echo and my heart is in good shape. (Otherwise, I'd be totally freaking out with these beats!).
Anyone else find that they get palpitations on any of the SSRIs?
Thanks for your help!

Thanks Karen,
I will probably see the doctor next week and see what he thinks. I was hoping if I took enough magnesium, the weird beats would stop, but they haven't. I went down a little on the zoloft, but that just makes me freak out more with the beats!
My GI tract has always been very connected to my heart, and it seems like when I have a GI flare (IBS/fibromyalgia, GERD), I can get these funky beats. Its never lasted this long though, and constantly. I'm also thinking it might be my funky hormones. Let's face it. I have a funky body!

Hey Cathy

Are you sure your having PVCs or PACs?  Do have your physician check it out.  Everyone has both but most of us never notice the premature beats.

It is always good to be sure it is not caused by a med or a cardiac problem.  Of course anxiety is one cause of PACs and SVT.

Good Luck and take care.
