I felt faint and went to Hospital. On the monitor my heart rate was 45. I have chest pains. On having an endoscopy found to have fungal infection (old complaint of Barretts Oesphagus) but this chest pain was different and feeling faint was different. Had monitor on heart for 24 hours. Not got results yet. Told had Brady cardia, never heard of it until now. What do you think?

Summarized question: Is bradycardia dangerous?
