Rate Response

Different brands have different types of rate response. Many of them work on motion, so they sense movement and raise the rate. Some of them use minute ventilation go by movement and respiration, and the last one is Biotronik's closed loop stimulation. I can't explain that one! But it uses an algorithm and learns. 

Pretty Ladies

Hi MG     .. Interesting question :-

Interestingly, your body doesn't really differentiate between good excitement ( seeing a pretty woman ) and bad excitement i.e. stress . Both trigger off the so-called  " Fight or Flight " response.

When you get any form of excitement , your brain triggers off a response in your Peripheral Nervous System so that your body is ready for action.   Heart rate increases , you breathe faster to increase oxygenation to your muscles , your eyes adjust to take in more light and your B.P. goes up

All these changes can happen within seconds.

As Tracey says there are various types of PM sensors . As far as I know the Closed Loop Stimulation sensor used by Biotronik is the only sensor which responds to these sorts of emotional triggers and is thought to be the most physiological Rate Response sensor on the market.

Why not get a Biotronik with a CLS sensor, line up some pretty ladies and try it out !

Please report back

Cheers

Rate responce

Thanks for you suggestion Ian but nowadays I do not think I could attract a line up of pretty ladies.

FYI my PM CRTD is a Medtronic and the RR is solely activated by movement. I`ve proved this many times to test it. For example my HR will not rise significantly while on a static bike but will rise if on a rowing machine. I can increase my HR while stting by purely tapping the PM very quickly. My HR will rise on my motorbike purely by movement and not through scaring myself!

My thoughts are that if as the experts say I`m 100% PM dependent and my HR will rise without movement(when seeing a pretty lady!) then maybe the the HR could be stimulated by the `flight or fight` brain responce messages which trigger the HR by a different pathway?

I am supprised than with so much reseach into PM`s the number of signals is so small . Even a modern car engine control unit will see perhaps 10 base signals and each of those will have variable maps all interacting.

Perhap I`m just simplifing things too much

Next time I see my EP i`ll try and get an answer.

I agree

I , too, have a Medtronic pacemaker and it relies solely on upper-body movement to increase the heart-rate and I find it really lacking as far as cycling and running goes.

The human body has many pathways to increase heart-rate when required .... movement , exercise, stress, increased breathing, seeing pretty ladies etc.

I find it surprising that Medtronic, the world's leading PM manufacturer relies on just one of these, upper-body movement. It really is quite primitive.

Let me know the response from your E.P.    Mine did not appear to be aware of the limitations of Medtronic .  I asked him to read up about it and he eventually agreed that I was right and has promised me a different PM at my first changeover.
