About 10 minutes ago while typing on my laptop, I felt this gulp feeling right in the middle of my chest and it made me jump a little bit. This feeling lasts for a quick second. Was this feeling a skipped heart beat? During the past year I have had 3 EKGs, 1 Echocardiogram and I holter which I did not get the results for. All came back normal. These feelings come around once or twice a week all lasting for a quick second, rest of the day I feel normal with a normal pulse. Should I have more heart exams done even though my other tests came back normal?
