I am on bisprolol 2.5 mg for inappropriate sinus tachycardia, which was thought to have caused/exacerbated my shortness of breath (which was initially caused by severe anemia but persists despite normal Hb [but ferritin is low normal]) . The bisoprolol also brought down my diastolic BP which suddenly shot up a few weeks back.
A few days before I started the bisoprolol, I felt some relief in the shortness of breath. No idea why/how. I've been on the bisoprolol for 10 days now. While my heart rate (between 70 and 80) and BP are great, I am now having more shortness of breath than previously. I even have shortness of breath at rest sometimes.
For the past few days, every time I take a nap I wake up feeling suffocated and have palpitations. I am not gasping for breath, but I do wake up breathing faster and with a higher heart rate. I was concerned if this was symptom of heart failure, so I slept flat on my back last night without pillows. I didn't experience any shortness of breath or palpitations at night thankfully. My recent echo, nuclear stress test, chest x ray were all normal, and the only abnormality is the high heart rate caught on various ECGs and the holter.
I am wondering if bisoprolol has anything to do with the shortness of breath and the suffocating feeling during naps. It's working so well for my heart rate and the diastolic BP (which was said to have risen because of IST) that I don't want to go on another med asap. I also have t2 diabetes (well controlled, a1c of 4.9) that I can't use nonselective beta blockers as they raise BG. I was on HCTZ (diuretic) which did nothing to lower my heart rate, and my diastolic mostly remained high on it, plus it raised my fasting BG over which I like to keep tight control.
but yes, if you have had worsening/new shortness of breath on bisoprolol, please share your experience. thank you.
