You have gotten some great suggestions here already. I would like to add that you could be experiencing an esophageal spasm, although mine lasted longer than a few seconds. Possibly you're feeling an adrenaline rush.
Scaredy mentioned GERD. She very well could be right. GERD can mimic heart issues, just like the aforementioned esophageal spasm. When I thought I had a heart issue, I had two EKGs. All good. Then my PCP at the time sent me to a gastroenterologist whom did an endoscopy on me and discovered GERD, a hiatal hernia, and esophagitis. His words to my mother were, "No wonder he feels bad." These conditions are quite treatable and often is nothing to get riled up about.
