Low was 46, high was 128. Right after I got my holter results, I was sitting at dinner and had a horrible crushing chest pain
while laughing. It was so bad, and so sudden that I went to the ER. They did blood testing and EKG's, all of which were normal. They diagnosed a pulled chest muscle. Ever since this incident 3 weeks ago, I have had terrible intermittent chest pain. Sometimes while sitting, sometimes, while talking, sometimes when standing/walking. There is no rhyme or reason to it.
