Information

Hi; I am new at this. I had received this CYLOS DR-T pacemaker. Also some of the record describe the pacemaker as DDDR. No one has ever explained anything to me, including the physician as to the selection of pacemaker and what one should know or do. I do not feel any different than before having this device..
Any one have any information on how they work and why the different titles. My card reads the cyclops but the doctor records say DDDR. Any help will be greatly appreciated. Thank You...Frederick.

Hi Frederick,

I am also new and want to welcome you to this great support group. I don't know the answer to your question, but I know some of our knowledgeable members will. They will probably post and you will get a lot of help and support.

I have a St. Jude pacemaker and have had it for 5 1/2 years with no probs. I am due for a new pacemaker as my battery has worn out and I go in the hosp. on next Wed. to get it.

Take care,
NH

I'm short on time right now or would help you a bit more, but go to Biotronik's web site for information on your Cylos DR-T pacemaker. The site is: www.biotronik.com You can search the name of your pm in the search box in the upper right hand corner and lots of different articles of information pop up for you to read. You can also do an internet search on the Cylos DR-T and get more info.! I'm guessing you have your pm for bradycardia issues???? You pm, I believe, is based off DDDR technology. I know I had a mistake on my pm id card and automatically got a new one sent from my company with the correct info. because they do their own quality control on what the docs send in. Hopefully someone else with a little more time on their hands will add their 2 cents!

DDDR...and all that

Hi Frederick

Welcome to the pacemaker club. I am sorry I am late with a response but I think I can throw a little light on your query. I know nothing about Cylos pacemakers but the letters DDDR have nothing to do with individual pacemaker makes, models or technologies. The letters DDDR are NBC pacing codes. "NBC" stands for The North American Society of Pacing & Electrophysiology
[NASPE] and the Btitish Pacing & Electrophysiology
Group [BPEG] Generic.
NBG has established a 5 letter set of codes which describe how your pacemaker is configured. Each 5 letter NBG code describes a specific type of operation for implantable pacemakers. Sometimes only the first 3 or 4 letters are given eg DDD, DDI, DVIR etc.
The pacing codes are defined as follows:

First letter gives the heart chamber paced.

V = Ventricle
A = Atrium
D = Dual chamber
S = Single chamber
O = none

Second letter gives the heart chamber sensed.

V through O as above

Third letter gives the response mode

T = Triggered
I = Inhibited
D = Double (Both)
O = None

Fourth letter gives the programmable/rate response

P = Programmable
M = Multiprogrammable
C = Communicating
R = Rate Responsive
O = None

So if your pacemaker is configured DDDR, it can pace the ventricle and the atrium, sense the ventricle and the atrium, have double mode of response and the facility to be rate responsive.

As to the selection of the pacemaker and what one should know or do, that is very much the province of your relationship with your cardio/electophysiologist.

Here in UK our NHS works very differently to US practice. However in the UK (and I guess the US), my experience is that it pays to be polite ....but persistent!

Best of luck to you and please let us know how you get on.
