I take atenolol 100mg daily in divided doses and absolutely has no break through episodes of tachycardia while on it at least not tachycardia for no apparent reason like before, i would really have to be frighten or exercising vigorously for my heartrate to even go up to the 130s and 140s, yet resting it still averages around 64 on even that dose of atenolol, I use to take to propranolol(inderal) 20mg x 4times daily and used to have break through episodes of tachycardia, been on atenolol everyday for 4 years now and have no complaints.I took it before for 2 years 1999-2001) but stopped it for 2, then restarted again(2003 to present).
I've had periods of IST off and on for years, as has my mother. I've never taken beta's for it, it just resolves once I get my panic/anxiety levels down.
Not so for my mom though. She's been on Beta's for 35 years now. For some reason the new doc she started seeing thought he would change her working beta, blockadren, to something newer on the market. Atenolol made her extremely fatigued, and she actually got worse on the metoprolol, so they put her back on Blockadren. Her symptoms were breakthough tachy, SOB, and a cough on the Metoprolol. I think I would put a call into your doc and tell him about the SOB and ask/insist to try another Beta ASAP. There's no need to suffer like you are!
I just went to a different cardiologist today and he said I have slight Mitral Valve Prolapse and changed my meds to Nadolol. He said it's an older drug that works better for irregular heart rhythms. My heart rate is a lot better today. Will start my new med tomarrow. He did advise me to take a baby asprin a day for the tachycardia. Has anyone taken the Nadolol? Thanks for all your responses!!
I never took nadolol personally, the brand name is cogard if i remember correctly. It is one the older beta blocker with a good record, it is said it is often underused these days. The usual dose for palps from what I remember is usually 20-40mg twice daily. Sometimes they start you off on 20mg daily just to see how it works for ya. Hope it keeps working good luck!!
