I am a 50 year old female who had a mini stoke 3 years ago. Since then I have had skipped heart beats, in the last couple years my heart dances off beat and then gets normal. I have suffered high blood pressure but that has come to normal all of a sudden in the last few months. Latter part of Dec 2012 I was taken to the hospital with rectal bleeding and found nothing wrong. No my heart beat gets real low, I have had problems with severe stomach cramping, watery diarrhea, and then switch to constipation. I am not losing any weight and no change in eating habits. When my pulse is low like in the 30s it gets hard to breath. I just had a heart cath done a couple days ago and it came back normal, no blockages but PVCs and the skipping every 4th to 6th beat. Dr told me to take 40 mg or Propranolol three times aday if that does not work in a month I might get a pace maker, or he said something about killing off the part of the heart that is not beating right. I have no clue that is going on, could it be damage to the vagus nerve from my mini strokes?? I do have a bladder problem also. Thanks Anita
