I was prescribed inderall for PVCs. I felt like it made them worse and stopped taking it. Sounds like a different situation than you.
janella49, you didn't say why u were taking the Inderal! I am 57 yrs old and took Inderal (for pvs and pacs) from 1980 until 2010. I guess my body grew immune because it now longer kept the symptoms at bay (racing heart and pvcs/pacs)! now, I take metoporol (75mg x a day) and that barely works.
Your "skipped" heart beats are likely not skipped beats but rather premature or "extra" beats, extrasystoles, PACs or PVCs. However, if this just started, and you haven't experienced it before or talked to a doctor about it, I would recommend that you do, and that you register an EKG at the doctor's office, preferrably while you are having the irregular heart beats.
If your EKG otherwise is normal, extra heart beats are not dangerous and will not kill you. They are, at least up to a reasonable number, considered a normal phenomenon which almost everyone have on occation. In rare cases they can be a symptom of disease, but they are not in themselves dangerous.
I used to take Inderal / propranolol and it helped both on extra beats and panic. However, it gave me "white coat hypertension" (exaggerated blood pressure response during stress) which made me stop taking it and switch to a cardioselective beta blocker against the extra beats. I'm also taking SSRI for the anxiety.
