Tonight, after dinner, I experienced a racing heart, sweating, shortness of breath and some chest pain when sitting down. I took my BP and it was 132/86 but my pulse was 145. After an hour of sitting, the sweating stopped, and my pulse lowered to 122 with BP of 119/82. I take metaprolol - 3 tabs per day, and am on blood pressure meds also and have been stable and managed for quite a few years now. When I checked my med dispenser, I wondered if I might have missed my morning metaprolol, because there was none for the morning compartment for the next day. So I decided to take my usual night dose of 2 early to see if that helped. Now my pulse is down to 109 but is not moving lower even though a few hours have passed now.
