Hi @predictable. I take Losartan for hypertension, Chlorthalidone which I think is a diuretic, and Diltiazem to help my rapid heart rate and Xarelto. I was hospitalized for three days, during which time my cardiologist tested for heart blockages and found none. While I was in the hospital, every few minutes a nurse was in my room to check to to see If I was still breathing because of my extremely low heart rate. I know that because of my athletic background and low resting heart rate is not unusual. However, my doctor was concerned because of how quickly the rate accelerated once I started to move around so he prescribed the Diltiazem. It just may be all in my head, but I could swear that I didn't start experiencing the hard thumping in my chest or the racing heart rate until I started all these meds. I had no idea I was in afib or had hypertension until I went to see a doctor about pain in my shoulder. I was told during the initial exam that my blood pressure was high and that I was in afib and was immediately referred to a cardiologist. It wasn't until after I started treatment that I started to feel the symptoms. Fatigue, chest thumping, chest pain. I've not felt normal since. I am definitely going to seek a second opinion because I just want to feel better. I can't believe that this is what I have to deal with for the rest of my life. It's been almost a year and I don't think I'll ever get used to feeling like this. I envy you having a medical team that communicate with each other.
