Activity level.

Can someone explain how they calculate activity on pacemaker.?   On my recent report it said 5.4 hrs. I would have thought it would be much higher. I have a Azure pacemaker.

I have an Medtronic Azure dual lead PM as well, but I have the app. Do you use the bedside monitor or the app ?? 

The My Care Link app has “ Physical Activity “ ( and other categories as well ) and it has Day, Week and Month and under each of those headings  it has hours.

Each day you will see the previous day’s activity level shown in a graph.

On my 3 month transmissions a graph is shown as well as average hours of activity. It also shows a 3 month daily average and mine is usually 7-8 hours a day. I’ve never seen anything higher than that. 

I like the app and haven’t had any issues with it.


Activity mode.. Settings.

I dont have the app. I got my information from my clinic portal. There were no graphs, just last week's average.

 Thanks for responce.

Just read your post again and I think I see a decimal point ! My first read was 56 hours. Oops...

I am going to look over my report again and see if there is more information available.

Thank's again.

Your Pacemaker Manual might have some useful info

Tachy, Look under Activity Sensor and related sections to see whether you can find the answer to your question about how activity is calculated. You could also check under Rate Response Activity Sensor.

If the 5.4 hours represents your daily average, then that might be correct for you depending on what parameters they use to calculate this figure. 

I see DC65 has given good info on the App, so you could start to use this too, to get a better indication of what is normal for you on a daily basis.  

Update might be worth reading the links below, at least the bits relevant. I have copied and pasted a short section from the first link on how they calculate activity which might help to start to answer your question.

The internal accelerometer embedded in Medtronic pacemakers registers, stores, and reports total “active time” based on a threshold activity intensity level of approximately 70 steps/min (estimated to be > 1.5 METs). The accelerometers in the pacemakers are useful for sensing the activity level and facilitate adaptive rate responsiveness to meet the physiological demands of the patient.

Good link about definition of MET's:

Thank"s for your help. There is a lot of info. to sort thru. Very interesting, however.
