Bradycardia. 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.
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.

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.

Several issues. This need not be just a cardiology problem. Have patient's own doctor check him for neck (spinal)problems, blood sugar problems, cortisol problems and peripheral neuropathy. Much more information is needed to reach a differential diagnosis.
Vasovagal. Could be vasovagal disease or neurocardiogenic dysfunction. It is diagnosed by tilt table testing. Go see an electro physiologist.

Look again - You may have an arrhythmia called inappropriate sinus tachycardia or another one called pots -- please find a good cardiologist locally to sort this out -- there is a treatment for this condition.
Revved Up. If there is no physical cause (such as heart or thyroid problems), these symptoms may be a sign of an anxiety disorder. In anxiety disorders the brain tells the body to stay in "panic" mode. Think of it like this - too much adrenaline when it is not needed, so the heart rate goes up, blood pressure goes up, etc. Being in that state takes a lot of energy, which is why you feel tired and out-of-it.
Panic Attack. It sounds u r having panic attacks, see your PCP for evaluation and treatment.
