Hi, I am a 24 y/o male whom experiences an anxiety like feeling in his chest while exerting himself, such as running. I would not describe it as pain, but when I run for a while, I will have these periods where it feels as though my chest is going to explode. I will feel a little queasy/dizzy during these episodes, but it subsides quickly.
I am a firefighter/paramedic, and while at work I conducted a 12-lead on myself. The interpretation was Sinus Bradycardia w/ irregularities, however I think the irregularities was just artifact. My resting HR is about 56. I have had stress tests, but I did not have the feeling during the test and of course I passed. Please help.

Would i be wrong in assuming that you are a very atheletic type of an individual, as your resting heart rate is low?
Resting Bradycardias in atheletes are quite usual and normal.
In other individuals, bradycardias may indicate some underlying abnormality.Symptomatic (Symptoms of bradycardia include fainting, dizziness, extreme tiredness, and shortness of breath) bradycardias should always be investigated.
In your case, as the symptoms came on during exertion,it is possible that at that point of time,you had developed a new dysrhythmia or prehaps your heart rate failed to increase proportionately.Are you an any medications(such as beta blockers?)
'Sick sinus syndrome' may need to be excluded.The other likely candidate is 'exercise- induced hyperkalemia',which can precipitate an acute change in cardiac rhythm.
You may not have experienced any problem during stress testing because the level of stress might not have equalled the stress of running.I think you need to be tested further to exclude some underlying cause. Best wishes!
