  • Shortness of breath and dizziness

    Hello All,

    I had a mild set back last night. I woke up in the middle of the night and felt short of breath and dizzy. To my knowledge, I don't think I've been in A-fib before, but am not ruling it out. I was reading some old posts about what A-fib feels like, and I still can't determine if that is what was going on. My pulse did not seem to be beating rapidly at all. I’m feeling a lot better today physically, but am still a bit worried.

    This is all concerning to me because I was feeling pretty much normal prior to switching medicines a little over a week ago. I was taking 50mg of atenelol in the morning and 180mg of cardia in the evening. I am now taking 100mg of toprol XL in the morning and the same in the evening. I seem to be waking up in the middle of the night suddenly now. (Don’t know why???) Is there an adjustment period when it comes to medicine? If so, when will I know if this current drug is the right fit? Was I possibly in A-fib because of the drug change?

    Just when I thought I had this thing under control, I've started feeling uncertain again. Does anyone think this is due to the medicine change? I must add (wince), that I played some VERY LIGHT 2 on 2 basketball yesterday evening. I know it is a bad idea, and that I will probably catch some grief for it, but I only did it for a short time during halftime of last night's game. I didn't even play defense, (Never did anyway) and my heart rate never even got above 120 BPM.

    Any advice, input, or recommendations would greatly be appreciated. I do have an appointment to see my EP a week from today, and will certainly be discussing this with him as well.

    Thanks in advance,

    In my opinion (for what it's worth) it could easily be the change in meds that is causing your new symptoms. Assuming that this is the only thing that has recently changed for you, it kind of adds up. I'm not a doctor of course, but I can speak from my own experience after trying out many different brands and types of drugs. There is an adjustment period for any new drug so it might just take some time.

    You should always inform your doctor of changes in symptoms though. I wouldn't just shrug it off and hope it goes away. He may want to adjust the dosage or try something else. So do please give him/her a call.

      I just realized your question is in the 'Ask The HCMA' section which is supposed to be for moderators and staff to answer. Sorry about that. When I look at the list of new posts daily, I usually only look at the topic and not where it is actually posted. Hopefully someone will come along to help you shortly.

          From Dorothy:


          Hope this is the right place to put this.

          I, too, have had the "waking during the night with sob and dizziness." In my case, I do not believe it to be afib, as I have been in different afib situations. I found, upon taking increased doses of Toprol XL, vivid dreams happen more often. Also, when I overdue on any one day, I can expect to wake during the night. I attributed those times to "over-doing" and in a deeper sleep during the night. Could be in such a deep sleep that breathing is too shallow. I really appreciate the "wake-up" call versus not breathing at all.

          I find that if I'm overtired and go to bed in a raised position, I do not experience such sob. May work for you, too.

          By all means, check with your cardiologist about drug change side-effects.

          Hope this has been of some help. Others are sure to add,
