Hi my name is sergio and i suffer from afib. it started when i was working in a restaurant.  People wore working on sealing the roof with some chemical. Everyone was complaining about the smell of fumes. After my shift shower, ate, and went to sleep. In the middle of the night with heart palpitations. I went to the emergency room and they did alot of test and they did not found anything wrong. From then on my heart has been having palpitations. I was 26 yld at that time. My cuestion is if the exposure to those  chemicals that we inhale for about 4 hrs it could be the reason.
Hello, I really appreciate your concern. Inhalation of certain fumes or chemicals can cause palpitation. I would like to ask you to what chemical you were exposed at that time. Inhalation for 4 hours can cause acute rise in heart rate, but it cannot exert chronic effects like you are mentioning. Atrial fibrillation is itself a cause of palpitation. But acute exposure to fumes do not cause atrial fibrillation.  So there is nothing to worry about the incident. I advise you to avoid stress of that incident and forget it completely. Anxiety or fear can be the cause of your palpitations. Try some relaxation exercise like yoga and meditation. Hope my answer has solved your query. Take Care. Thank you.
