Hi, I am 23 years old, female. I have been noticing that my heart suddenly beats very fast for a few seconds, and then it comes back to normal…this process ends very quickly. It used to be once or twice every week since a few weeks prior but now its happening for atleast 5-6 times every day. I checked my pulse during that time and it was 74 first, jumped to 112 for 10 seconds and then came back down to 84. As of my now, my pulse recording is 119. Is this something to be very concerned about?
