Can excess tuna fish consumption cause tightness in chest?
Patient: my son eats alot of fish...tuna, exercises hard each day, does alot of cardio...once had tighten of chest at gym...his ekg was adnormal...doc said maybe sinus bradycardia..now has to go trough 24 hour heart monitor and echo...never took a mercury poison test...should he do so. never had a problem with heart..only one time short breath pulse is 38-46... Doctor: Hello!Welcome and thank you for asking on HCM!Regarding your concern, I would explain that bradycardia is quite normal in healthy and active persons. It can be related to chronic physical activity in sport persons. I agree with your doctor that a Holter monitoring is necessary to investigate his heart rhythm for a prolonged time. A cardiac ultrasound is also necessary to investigate for the presences of cardiomyopathy. Regarding the fact that he eats a lot of tuna, I agree with you that he may be at risk for mercury intoxication. For this reason, it is necessary performing mercury plasma levels. Hope you will find this answer helpful!Kind regards, Dr. Iliri
