Hello! Welcome and thank you for asking on Chat Doctor! Your symptoms could be related to a panic attack. But, cardiac arrhythmia can not be excluded either. For this reason, if this situation repeats, I would recommend consulting with your attending physician for a careful physical exam and some tests
