palpitations that you have could be just due to anxiety
and be normal.
but at your age it is better to get an ECG and physician check up to rule out arrhythmia
(abnormal heart rhythms) which if missed and present, can be dangerous..one exam may be normal.. may need ECG when you actually have it (fluttering )
just get evaluated and be reassured if all is well.
pl. keep me posted.
thanks for your query and I hope to have answered you well
