settings perhaps

I had a medtronic DTMA2QQ fitted in January this year (3rd), everything is healing up nicely, yes you know its there but generally its good, my basic problem stems from MI in 1993 Cabg1994 left ventricular dysfunction, which as time has passed got worse to the point where EF was down to 34% hence the CDT-D, and yes it makes a difference, the crushing breathlesness has gone, I can still get out of breath if I push it, but not like before, what I am still (despite reading as much as I can here) unsure about are the declared terms on my implant record card, so what is Brady Pacing with DDD 60-130 bearing in mind that it appears that my resting HR is , overnight as low as 48 and usually around 50, sometimes now I am waking in the morning really breathless which concerns me, any pointers towards a proper explanation would be great, at my first clinic, the clinitian was not really forthcoming with the kind of info that would give peace of mind, let alone settle my logical appreciation of the functionality



Get a copy of your HR curve

DDD 60-130 is a very basic setting. All it means is it will not let your heart rate go below 60 (unless you have a night rate on, which would explain the 48 you mentioned). The higher number is how fast the pacemaker will follow the top part of your heart with a bottom part pace if necessary.

You do not have rate response on, so if you need that, you aren't getting it. You can verify this by getting a copy of your HR curve from your device check.  My personal thoughts on Rate Response (with some exceptions of coarse) is to always turn rate response on even if the patient doesnt need it. If you don't need it, then it doesn't do anything, but its there just in case.

If you are open to a second implant, send me a PM and i'll give you some info on a really amazing device you can look into that is available to you since you are in the UK.

So, my advice is to go about your daily routine and forget that you have a pacemaker implanted in your body.
