AS for SSRIs, I take only 5mg of escitalopram(lexapro, cipralex are the brand names) it works wonders for a pounding racing heart, also
PVCs , at least it did foe me, if one don't work another might for example citalopram caused some unwanted side effects for & escitalopram , no side effects at all, they are very close to being the same drug, except escitalopram is a purified version. Good luck tachygirl , I know exactly how you feel.
