Could red bull cause irregular heartbeat?

My 30 year old son had a physical yesterday and was diagnosed with an irregular heart beat. He had been on a business trip all week and was exhausted from jet lag. He did say he had a Redbull just before the visit. He does have an appt tomorrow morning with a cardiologist. He is in excellent health - and is pretty much a health food junkie and works outs regularly Could it be fom the Redbul?

Cardiologist 's  Response
Hello!

Welcome and thank you for asking on HCM!

Regarding your concern, I would explain that Red Bull can trigger this situation, because it contains caffeine, which can activate the sympathetic nervous system, thus leading to release of adrenaline and noradrenaline, which can cause an increased heart rate and even ectopic heart beats.

Anyway, I recommend consulting with his attending physician for a careful physical exam and some tests to exclude other possible causes:

- a cardiac ultrasound to examine your heart function and structure
- an ambulatory 24-48 hours ECG monitoring to examine your heart rhythm trends during a prolonged time
- complete blood count for anemia
- thyroid hormone levels for thyroid dysfunction
- blood electrolyte for possible electrolyte imbalance.

Hope you will find this answer helpful!

Wishing all the best,

Dr. Iliri
