Update on Zachy

So today was Zachy's appointment.
When he was originally paced, they were happy because he was able to get his heart rate up on his own. And by that I mean while active his heart would raise to the proper level. So, his heart rate was very low, but when he got active, he was able to get it up on his own.
That isn't happening now. So, he was being active, and his hr wasn't going up very much, causing him to be tired.
The dr changed the settings on his pm to now include the higher rates. So now, when he gets active, his pacemaker will kick in and raise his hr to a higher level, where it needs to be to properly oxygenate him.
We are happy about this, because it was a simple fix. We hope. We still have to wait and see if this takes care of the problem. It is a bit troubling though, because a year ago he was able to do that on his own, now he isn't.
Time will tell what the future holds for Zachy. But right now his heart looks great and strong, just a bit lazy.
