Heart beating fast: While an organic heart problem cannot be ruled out , you may be experiencing mild panic attack like symptoms. The first right thing to do is go to the campus clinic for an evaluation . Don't delay .

Maybe SVT: Supraventricular tachycardia (SVT) usually has over 150 beats per minute and may go up even faster. A person may feel she has a pounding heart (while resting, not exercising). She may also be short of breath, breathing fast, feeling dizzy, and sometimes faint. If a person is anxious or gets anxious, and then her heart rate increases, that may be anxiety. SVT turns on suddenly, without anxiousness.
