Hi kenna0077

I doubt that any doctor would proffer an opinion regarding your situation on this forum. You don't say whether the doctor (or doctors?) whom you saw was a specialist. If s/he wasn't, I think that the only way of getting an opinion of value one way or another, and of hopefully having your mind put at rest, is by persuading your mom to take you to a recommended cardiologist for a series of standard tests. These are not invasive, so you have no cause to worry about them. On occasion, asthma is misdiagnosed and the real problem is a quite different breathing disorder - a type of pulmonary hypertension related to heart disease; but such misdiagnoses are unlikely to be frequent these days, I would guess, and a good cardiologist would soon tell you whether a non-specialist was right or wrong in this regard. Irregularities in heart rate can be benign or, especially if they are frequent and episodes are sustained, can point to cardiac disease. Here are some examples to illustrate the above points: One of my sons has asthma but has been cleared by a paediatrician of having any heart defect. In childhood I received diagnoses of "growing pains" and "bronchial asthma" and was found, after some years, to have a malformed heart requiring surgery. My granddad had diagnoses of "exercise-induced asthma" and then "persistent asthma" but the true problem was the pulmonary hypertension that I have referred to above. All three examples are of people who are or were physically very active. So, like the asthma and the isolated case of a racing heart rate, your level of physical activity will not indicate whether or not you have a cardiac issue. Your age would suggest that you are still at school and at the point where learning unavoidably brings stress. You will have enough to worry about without additional anxieties concerning the health of your heart. Have a good, calm talk to your mom about the advantages of getting cardiac testing done. I wish you the very best outcome.

You should see a electrophysiologist for a work up. At age 16 I do not know if you are still considered a "pediatric" person but none the less the description you detailed indicates that you have experienced some sort of arrhythmia. That you have experienced issues the past since your were 11-12 suggests that there might be an underlying issue. I would gander to guess what it is but move on to see a good EP for a work up.

I am not a doctor, but had same problem for 7 years starting age 14. Discovered it was from caffeine which some people like me can be extremely sensitive to it.

If you are drinking or eating anything containing caffeine, stop all and let us know what happens.
