Interested to know if anyone has a combination of mild COPD (no trouble breathing), AFIB and PVC’s. Heard that COPD can cause some heart irregularities. Have read that metoprolol succinate (which I am taking) may create more problems with the lungs which may lead to more heart events. Been taking it about three years. Last couple of months getting more fluttering palps after mild exertion. Haven’t had an AFIB episode in 45 days, whereas they had been happening about every 10-14 days at its worst. Can’t figure that one out. Is anyone being treated with a certain combination of medications so as to accommodate both heart and lungs without one affecting the other in an adverse way.
