Medtronic advisa a3dro1

Hey all

Just had my sorin pacer changed the dr decided to go with a medtronic advisa a3dro1. My leads were fine so werent changed they are medteonic leads. My question is this. I am 38 and active. Its been 3 weeks since my change and i have been cleared to do more than just walking today was day 1 on the treadmill i got up to 2.5mph not fast at all and my heart rate automatically jumpped to 180 which is my upper setting. So i walked for a bit and stayed there for the entire time. I stopped and went back down to 60 started again and rigjt back up too 180. I decided to monotor more than i ahve been and with any extended walking i go up to max with very little effort.

Now if o remember correctly rate resonse pacers adjust to movement and breathing so will this "learn" as i become more active or do i have an abnormally sensitive pacer.

This is my first change and i feel like i had a similar phase when i got my origional in but 9 years ago and very ill bavk then.

Would love feedback

Keep fighting all!!!!

Rate Response

by IAN MC - 2019-01-03 06:15:11

Hi Chris    It certainly sounds as though you have Rate Response switched on to get your heart-rate up when you exercise. It also sounds as though you need an alteration to the RR settings which is an easy fix.

You have changed from Sorin to Medtronic . Some Sorin PMs have Rate Response dual sensors i.e. they detect movement/vibration AND changes in breathing whereas the Medtronic Advisa ONLY detects movement /vibration.

Assuming that 180 is your maximum sensor-rate setting  it will put in extra heart-beats up to 180 and then no higher.   The level of exercise needed to trigger off the RR sensor can be changed i.e. so that it responds to mild / more active or vigorous movement. Perhaps yours is on too sensitive a setting ?

In addition to this it can be adjusted to change the time it takes to get to 180.  It certainly sounds as though , in your case, this is also a setting which needs looking at, 

They can also change the rate at which your HR will return to normal.

Just to confuse things there is also a maximum tracking rate but this is nothing to do with rate response.. it is a safety measure to prevent your ventricles from keeping up if you should ever go into atrial tachycardia.

I have a Medtronic Advisa myself and have had many alterations to the RR settings. You will get there eventually !

Best of luck

I just want to share about the quality of life after my pacemaker, and hopefully increase awareness that lifestyles do not have to be drastically modified just because we are pacemaker recipients.
