Sorry I can't help much with your concerns. Is your cardiologist an Electrophysiologist (heart rhythm specialist)? If not, it might be a good idea to try and see one. They are much better at diagnosing and treating heart rhythm problems.
Good luck and hopefully someone here will have some advice for you.
I am so sorry that you are experiencing the rapid highs and lows. I agree with stevie_wonder in going to see an electrophysiologist for your rhythm problem. I have had a pacer for three years and two weeks ago I had it replaced because the algorithm was not detecting my P waves when I was in AFib and could not pace me out of it. My new pacer is working beyond my expectations. I have had considerable work done on my heart and at times was on a boatload of meds. In a month, I will be med free and skipping down the street. So if your pacer is not doing the trick, an EP can analyize your situation. Good luck to you. I know what it is like to have a pacer that does not function to meet my needs.
Thanks for the comments. He is an electrophysiologist. He seemed to think my high rates were not likely anything serious and that it is normal for a heart to go up and down like that. But on the other hand he ordered a 2 week loop monitor and told me the possibility of surgery or medicaition. Who knows, but the pacemaker lab seemed more concerned than him. Better that way then to have the specialist concerned!
Ksig is right. He has those experience.
My cardio told me my pacemaker has a build in holter monitor. This pacer is not implanted recently, it's implanted in 2002. At that time, most pacemaker already have a build in holter monitor. You're sure your EP knows a lot of your pacemaker? Have you try on internet to check what functions that your pacemaker have? Are you on 2 leads or 1 lead? Get your pacemaker interrogation report has a look. Make sure the one that you have is turned "on". Although my pacer has many many functions but most of them he turned "off". Why I said that because the doctor has too many patients. He can be mixed up and forgot who has what. Especially if your doctor is near pension!
hi dante, i totally understand bcuz im having very similar experiences ..i have a duel chamber pacemaker which is controlling my slow/brady heartrates but my fast/tachy 1s r getting worse (a-fib & some v-tach) causing me 2 faint alot again & get short of breath & exhausted easily with my heart thumping out of my chest. my cardiologist & ep drs have both said yes its dangerous but nothings wrong (what??? u cant have it both ways!!!) & the ep dr is refusing 2 c me further stating she doesnt know what 2 do. ive seen multiple ep drs in ny with no help, but i recommend u at least try 2 c some urself. i know its tough but try 2 hang in there!
