I called for an ambulance, and when they arrived, I was given nitro. It brought the
pain level down somewhat, but also made my
chest feel hot. A second nitro was given, and the pain reduced to a tolerable level.
Shortly after arriving at the hospital, the pain came back. I was given another nitro, which brought it back down to a dull roar, so to speak. While I was in the ER, I noticed an odd pattern on the heart monitor.
