Muscle twitch/spasm: It is likely that you are experiencing some muscle (pec muscle or intercostal--muscle in-between ribs) spasm. It is not likely to be heart or lung problem because of its brief duration, and seemingly occuring rather randomly? I would do some good stretching/deep breathing/breath-holding exercise. If symptoms don't improve or worsen, consult doc for an evaluation. Good luck.
