39 yo, Active Runner with PM for sick sinus syndrome
I'm a 39 year old active person who's had a Medtronic PM for about 2.5 years. Long story short, was diagnosed with sick sinus syndrome and historically not had an issue elevating heart rate so just had the PM set to kick in at 50 bpm and had rate response turned completely off.
Lately, I've noticed on runs that my heart rate will go to about 160 and then afater about first mile (~7:30 minutes) that my rate will start to slowly decline and by 15 minutes in I could be down in the 120s. We've made some PM setting changes today that I wanted to run by this group and also see if anyone else has had any similar issues since my main issue now is just helping my HR keep up the pacing that it should be doing while particpating in significant activity. As it stands now, I get severely fatigued and have to stop exercising/running once it gets into the 120s or teens.
Setting changes are as follow:
Rate Response: On
Activity threshold: High
ADL: 70 (changed from 95)
Upper Sensor: 160
Deacceleration and Acceleration: 1
Thanks for any input!

I am not planning on letting any of this shorten my life. I am planning on living a long happy battery operated life. You never know maybe it will keep me alive longer. I sure know one thing I would have been dead before starting school without it.
