I came to a realization today. Every time a I drive my car my heart rate spikes significantly. It is exciting to drive, but not that much. I have a pacemaker, so it is pretty obvious something is affecting it. After doing a lot of reading it is apparently not too uncommon. The rough ride makes the pacemaker think I'm exercising, so it speeds up my heart. It feels really weird, but apparently is not a dangerous situation. I'm going to see if they can maybe adjust the sensitivity at my next checkup. It's certainly not easy getting old!
