The irregularity continued so I told Kathy about it after she got up. She, being the good nurse she is, checked my pulse and blood pressure and said it looked like I was throwing PVCs. That would be premature ventricular contractions. So off to the ER we went to get me checked out. As active and healthy as I am, I didn't think I was having a serious problem but Kathy told me that any time the heart is not working right you need to have it checked. I guess there's some sense in that.
Other than throwing a lot of PVCs, the heart monitor would also alarm when my pulse dropped down to 38. My normal resting heart rate is in the 40's and the low 50's. I did not know that until today. Kathy had to set the monitor alarm to a lower threshold, 35, so it would go off so often. However, the frequent PVCs made up for it and the alarm still sounded every minute or so. Nobody came running because my nurse knew Kathy and knew Kathy as watching me and knew Kathy would call if something was wrong.
All the test results said there was no infection or blockage or failure causing my symptoms. The doc said my fixtures and plumbing are fine and it's apparently an electrical problem so he cut me lose with a referral to a cardiologist. In the meantime, I can continue with my normal riding and running activities. He said that it's possible that my resting heart rate is too low and my heart is reacting to the slowness by creating extra, and useless, beats. Perhaps I should take up some slothful activities to balance out the physical exercise.
