Can you switch to another medication? Clearly this one isn't working. I suffer from PALPS all the time, skips, flutters, pounding heart, etc... They always scare me. But, after reading the hundreds of posts on here, it seems that many of us suffer from them. I usually take Xanax when they get bad and then they go away. DO you have Xanax or clonazepam that you can take to prove to yourself that it's just anxiety?
