SVT: Supraventricular tachycardia is a possibility. You can try vagal maneuvers such as holding your breath, or bearing down like you are having a bowel movement until you can seek out medical help. This could also be a very serious malignant arrhythmia so get checked out asap.

Heart Palpitation: Experiencing heart palpitation and shorteness of breath could be caused by many things including a serious heart condition. Having more than one episode and especially if it happened at rest, it warrants an urgent evaluation. A complete history and physical by your doctor would the first step to take.
