I went to the doctor for a completely unrelated matter and now I've been getting every test in the book because of a slow heart rate and a very infrequent fainting spells. No one ever seems to give me an answer. The only thing that I’ve found out after an ECHO, holter monitor, and two EEG’s is that I have a slow heart rate (which they found out on my indicial visit for an unrelated matter) and that my right-sided chamber is slightly larger than normal (is this good/bad/indifferent). My heart rate goes from 37 to 144 beats. My reports say that there is no ventricular ectopy, very rare supraventricular ectopy, and no arrhythmis. I have no clue what any of this means. Can someone please decipher this information and tell me what is wrong with me?
