Having Chest Aches And Gettng Windy After Taking Bisoprolol For Sinus Tachycardia

I m a 35 stay-at-home mom. Last week, I was diagnosed with sinus tachycardia after pulling my son on a sled through the snow landed me a trip in the hospital. All bloodwork (including a d-dimer test since I had traveled twice in the past year) came back normal. I was unable to take a stress test because my HR went up to 162 just from standing! They did an electrocardiogram, which was completely normal. I was put on Bisoprolol 2.5mg, but two days later I was rushed to the ER again because of severe heart palpitations and symptoms similar to a heart attack. My dose was increased to 5mg. I was also diagnosed with gastritis and put on PPI s twice daily. My appointment with my cardiologist is next week, but I ve been experiencing some different symptoms. I m not tired, but I do get winded easily...even when just talking on the phone. I get minor aches in my chest upon exertion, and feel like I have to stop. Waking up in the morning is the worst! I feel discomfort in my chest and feel almost as if my heart isn t beating at all (low HR?). Are these symptoms all related to the Bisoprolol?
