Lately my heart seems to be acting up making it hard to breath, feeling nauseated, getting dizzy and I get headaches at times. I recently had a 24 hr Holter monitor done. The results say that my HR ranges between 54-133 with an average of 84. However, on the interpretation says the baseline rhythm is normal; Atrial ectopy says Rare PAC's (<5/hr) and it also says the symptoms did not correlate to rhythm changes. Can anyone help in understanding the results. I'm being checked for dysautonomia but my appointment isn't until October so I would like to get an idea of what might be going on here. I really appreciate any help I can get!
