Hi. I am a 27 year old female, fairly athletic, bulimic (normal weight), and I have had a low pulse for the last month or so, ranging from 42-33 bpm. I have chest discomfort, fatigue and palpitations. Around Christmas time I was advised to visit the emergency room because my pulse was 37 bpm. They did an EKG and gave me some potassium, said my heart was structurally sound... I'm wondering if I should be concerned about the persistence of bradycardia and the other sysmptoms?
