Heart Rate change with new meds

[RSTING69]

This is going to sound weird, but I have been suffering from SEVERE anxiety issues since last summer, severe abdominal pain, shakes, etc.  I have had echocardiogram, nuclear stress test, tons of ekg's and ecg's, cat scan of chest and stomach, tons of blood and enzyme tests, everthing other than slight right side heart enlargement, is fine.  I was diagnosed with benign PVC's last summer by my cardiologist after wearing a king of hearts monitor.  My PVC's were controlled with 75MG of toprol XL to start, then my physician increased it to 100MG until my ECHO last year.  I stayed at 100 for a while as it really helped with my PVC's, but about 2 months ago, my doc knocked me down to 50 MG a day due to low heart rate which ran around 51-60 normally.  After going down to 50 MG, PVC's and Anxiety picked up again.  Doc put me on 50 MG of zoloft and 4MG of lorzepam to sart, worked ok for a while, then started to fade.  Went back in Last week and doc raised zoloft to 200MG per day and my Toprol to 75MG a day to help with PVC's.  Well PVC's are virtually gone now, however, had an episode the other night that I am wondering if it is linked to this medication change.

I ate some bad food the other night and began having flu like symptoms that night and started with diahrea, aching feeling in body.  Around 2AM awoke with water diahrea and extremely rapid pulse, but only while on the stool, was racing at 120-130 beats per minute and almost felt chaotic like I was getting PVC's in there sometimes.  Once I laid back in bed, rate dropped to low 90's but was still high for me.  Called doc and nurse said I was dehydrated and that is what caused the rapid heart rate.  Now two days later, my heart rate is still running around 70-75 when it used to run 58-60 normally before this episode.  Is this due to the medication and can zolof and toprol in combo increase the heart rate, my doc seemed more worried it would lower it.  I am just worried and confused, any help would be great

Thanks Jerry, yes the condition has improved greatly, my PVC's seem much more subsided and the heart rate seems to have settled down to around 68-75 depending on what I am doing.  I appreciate your input, what do you take Toprol for?

No easy answer here, but it sounds like all the problems related to something you ate stimulated the heart kick-back.

Toprol seems to have a strong affect on your heart rate, it is much less so on my too fast rate.  So it seems very possible that the changing medication dose level could be stimulating some of the variable HR.  

Another day has passed, has the condition improved?
