Have not been on my mountain bike since November 1

I went on a 50 mile ride on the first of the month. That evening my Dad's heart rate went up to 140 beats a minute, normal is in the range of 65 to 80, so had to rush him to Kaiser Hospital. He has been in and out of the hospital since and between taking care of my Mom and him I have had no time for a ride. I was planing to go tomorrow but looks as if that is out too.  Today he was fitted for a heart monitor which he was to wear for 24 hours. However after 5 hours it became disconnected and I was not able to restart it so I will need to take him to Kaiser sometime tomorrow. Hope we can come in the morning.  I will call Kaiser tomorrow.
