Dizziness, Shortness Of Breath, Fainting Spells, Heart Racing. EKGs Showing Branch Block, Infarct. On Sleeping Normally EKG Becomes Normal. Causes ?
It sounds to me like you have a stress induced cardiac arrhythmia. This is not uncommon and is due to the fact that when you get stressed out it makes the central nervous system more irritable predisposing to irregularity in heart rate.
As far as what I would recommend I think it would benefit you to have a 24 hour cardiac monitor which would help your doctor identify any changes in the rate or rhythm of your heart. That way he will have an idea of what he might be able to do to help you. Sometimes a low dose hemoglobin because derangements in these can lead to abnormal heart rates.
I thank you again for the query and hope my response has been helpful and informative. If you have any additional concerns i would be happy to address them.
Sincerely,
Dr. Galamaga
