Bradycardia: I agree with medical student, david miller- bardycardia is defined as a heart rate below 60 beats per minute. It can have a wide variety of causes and can certainly cause the symptoms you described. He needs to follow up with is doc and possibly see a cardiologist.

Maybe a sign of....: The slow heart rate could be a sign and not the etiology. Pts with vasodepressor syndrome or nuerocardiogenic syncope can present like this. A stress echo , a holter , and a tilt table test along with labs including thyroid panel should be done . A complete h&p should be done of course and a list of all meds including natural supplements.

Low heart rate: Unless your boy friend is athletic or on certain medication, the heart rate of 44 is low and may be causing his symptoms. I would call the er physician who saw him for a plausible explanation for his symptoms and then follow up with your doctor.
