Heart palpitations are sensations where you become aware of your heart beating. This can feel like a rapid beat, a flutter, a thump, or a skipped beat. Doctors will often ask about when these feelings occur, how long they last, and if they are accompanied by other symptoms like dizziness or chest discomfort. Keeping a diary of when palpitations happen, what you were doing, and how you felt can be very helpful. Seek urgent care if palpitations are new, very frequent, accompanied by chest pain, severe shortness of breath, fainting, or severe dizziness. We'd love to hear your experiences with heart palpitations.
