Mode switch

Hi!

IPG = Implantable Pulse Generator = other word for "pacemaker".

The mode AAI --> DDD means that you have the mode switch on: They pacemaker will switch from a modus where it only paces and senses the heart's upper chambers (atria =A) to a modus where it sense both, the upper and lower chambers (D = dual = atria & ventricles). This switch happens whenever the device detects a certain amount of heart blocks (AV block) in a certain period of time. A heart block is an intermittent or permanent blockage of the conduction pathway between the atria and the ventricles; when there is a block, an impulse from the atria is not passed on to the ventricles. This mode switch is a special feature not every pacemaker offers. I know that the Medtronic Adapta (and probably some other Medtronic models) has it, and also the Sorin Reply DR. It's designed to reduce the percentage of ventricular pacing. This is important because several studies indicate that a high percentage of ventricular pacing is related to an increased risk of developing heart failure or getting atrial fibrillation. So, in those patients who only have intermittent (not permanent heart blocks), one tries to reduce the ventricular pacing to a minimum.

Hope this helps.

Best wishes

Sounds familiar go down to...

...a post w/ the title "Heart rate rapidly dropping." It's about 19 posts down the list. Until you read the comments, you will not find anything that makes it sound similar to your situation. HOWEVER - that woman has her PM set in the same MODE as you - AAI-DDD.

Based on the lack of detail in your question, that is a good place to start - see if your situation matches hers when you read ALL the comments.

If that does not help, come back & let us know & someone will jump in to help. That one embarrassed me because the woman did not tell her whole story to start. Even forced a PM Tech to make some wild guesses. His were better than mine, however.

BTW: Call your IPG a PM - more common term for the little device. I had to look up the meaning of IPG to know what you were asking.
