Wrong age for heart: Hear attacks do not occur in 22 year old. Tachycardia can occur, it can be sinus tachycardia versus supraventricular tachycardia(svt). That is what you need to find out as svt is the only diagnosis which best fits your description. It usually recurs...So watch out for persistent palpitation attacks like this one again.

Not related: Troponin is more related to cardiac damage, such as heart attack. Your heart rate high may not result troponin increase. It is the cardiac electricity problem. Long lasting heart rate can result cardiac muscle death and then i crease troponin.
