I wish I could help more, but, here is what I think. I feel you are having a reaction to the Zoloft, it takes awhile for it to get out of your system, and, from the very beginning, you could have been having a reaction as you posted that you started the PVC's and other uncomfortable feelings when you started it.
Having good tests results are a good sign. One question, have you been tested for a hiatal hernia. From reading your symptoms, I would swear you have one. The pain one can cause is just like a heart attack in some folks, especially if it is a more severe one. It can also cause all kinds of irregular heart beats. Also, it causes acid reflux, and when you lie down, they really act up. I have one, so, I am speaking from experience, they are horrid. Being overweight can contribute to having one as well, so can anxiety.
I think lots of the symptoms you have described are anxiety related, and if you have a hiatal hernia, it is causing them to be worse. I would almost bet money on the fact that you have one.
If the doctor you are seeing is not concerned enough to check out other things like the hernia or other gastric problems, then, please see one that will, I bet they will find the culprit to be a nasty hiatal hernia.
Oh yes, I also get the same symptoms you are talking about when I need an adjustment from my chiropractor, besides having a hiatal hernia, when certain vertebrae in my back are out or even in my neck, I will get these horrid feelings, so, there is another route for you to try also. Most of the time, drugs are NOT the answer. Having vertebrae in the neck out of alignment can certainly cause all kinds of anxiety and nervousness.
Hope this helps you. Try not to worry, see another doc, and in the mean time, if you can, drink two ounces of Pure Aloe Vera juice twice a day and before bed time, if this helps, then you will know you are on the right track regarding the hernia or other gastric problems.
Oh yes, there are some folks in this forum, probably archives that have posted about their experiences with hiatal hernias and PVC's etc. Do a search, it might help also.
I now how you feel.. it is sooo scary...I have been having the skipped beats , pause outs, and flip flops and then racing heart on and off for years and it all scares the heck out of me I feel like I am gonna just drop at anytime and die! it is horrible. Over the past two weeks I have had a echo ekg and holter monitor and I get all the results on monday and I am so scared. My anxiety level is through the rough just waiting. Please know you will be ok .. I know it is soooo hard to believe but we are all still here from these horrible things. I too have 4 children 2 grown , though I have a 9 yr old and a 6 mo baby! I too dont want to leave my kids.. my husband does not understand the crippling fear that these bring on, but know we are all here going through the same things! hang in there, I am trying to still cope with them too.
