It feel like; completely randomly (sometimes when im mildly stressed) like my chest randomly kind of hurts; like someone just kind of grabbed my heart and prevented it from beating for a second, then slowly releases over 1-2 seconds. Feeling my heart beat a couple seconds later, it feels fine though. I ve had about 3 or 4 of these in the last few (3) months. If you recommend me to go see a specialist, I m defiantly not going to pick you as best answer. Thanks.
