Should I be playing tuba with heart palpatations?

This one takes a little bit of a backstory. I'm a girl, I'm a junior in HS, and I play tuba. And I have heart palpitations, a few times a day (but not every day, only a few days a week). They really just started-which is to say I started noticing them-about Christmas time this year. I'm not exactly petite, but I'm average weight and short-ish. The other 4 tubas are guys, so not exactly understanding enough for me to ask them. The question is, should I be playing tuba although I have these heart palpitations (that get worse when I play, but tolerable)?

I want answers from people that actually have a good opinion-not a 'I don't know, hmm...' kind of answer. If you're in band, have the same problem, or know heart stuff, that would help a lot.

I think if they are worrying you you should take a step down to barritone, and that might help you a lot. good luck

 
Heart Palpitations

Definition

A sensation in which a person is aware of an irregular, hard, or rapid heartbeat.

Description

Palpitations mean that the heart is not behaving normally. It can appear to skip beats, beat rapidly, beat irregularly, or thump in the chest. Although palpitations are very common and often harmless, they can be frightening to the person, who is usually unaware of his or her heartbeat.

Palpitations can also be a sign of serious heart trouble. Palpitations that are caused by certain types of abnormal heart rhythms (arrhythmias) can be serious, and even fatal if left untreated. Recognizable arrhythmias are present in a small number of patients who have palpitations. Immediate medical attention should be sought for palpitations that feel like a very fast series of heartbeats, last more than two or three minutes, and are unrelated to strenuous physical activity, obvious fright, or anger. Medical attention should also be sought if palpitations are accompanied by chest pain, dizziness, shortness of breath, or an overall feeling of weakness.

Most people have experienced a skipped or missed heartbeat, which is really an early beat and not a skipped beat at all. After a premature heartbeat, the heart rests for an instant then beats with extra force, making the person feel as if the heart has skipped a beat. This type of palpitation is nothing to worry about unless it occurs frequently. Severe palpitations feel like a thudding or fluttering sensation in the chest. After chest pain, palpitations are the most common reason that people are referred for cardiology evaluation.
