I am a 36 year old female recently diagnosed with a fib. Was hospitalized two weeks ago (only overnight) heart rate was 195 when I went to ER, took 10 hours to reduce to normal, also irregular heartbeat. Was put on Sotalol 5 days ago. Irregular beats getting more frequent and intense especially today. Checked pulse with blood pressure monitor read 144/78. Went to a drugstore to use their machine it read 148/87. Am not sure whether this is bad but not feeling altogether comfortable with frequency of irregular beating. Should I go to ER or wait til Monday to call cardiologist?
