I have been feeling these bursting sensations followed by rapid heart beats and tingling in my throat for several months now. Although the EKG, monitor and xray all turned out normal my doctor suspects PVCs. This week he started me on Toprol-XL for 30 days to see if the episodes subside. I'm on my fourth day taking 50mg. My stomach is starting to bother me.
Gastric pain is a side effect.
I plan to call the doctor tomorrow if the pain intensifies. I have had one PVC attack since being on Toprol, however, the symptoms were lessened and I believe the anxiety of having it was more troublesome than the occurance.
