I am new to this board, having just gotten a PM on January 10th of this year. I was experiencing bradycardia with SOB and feeling dizzy. I also had a history of PVCs which was diagnosed in 2019. My pre PM diagnosis was
Mobitz type II and 2:1 second degree atrioventricular block.
The reason I decided to respond is that I also have a Medtronic Azure PM, and and it seems, a similar diagnosis .
I just had a monitor check at the device clinic two weeks ago. They estimated a battery life of 14.3 years.
The ventricular lead is pacing at approximately 99.2% and the atrial pacing at approx. 9.1%

About 3 days after they put in the PM , I had a really bad feeling arrhythmia and so I sent in a strip from my medtronic ap. to the device clinic and it showed repetitive nonre-entrant ventricular atrial synchrony (RNRVAS). So then, to prevent the RNRVAS, the PM was reprogrammed to pace only when my pulse got down to 50.
I really don't have all the details otherwise as to how it is programmed.
I have had several other device checks and each time their estimate is a little different as the life of the battery. When I went in to have it re-programmed 5 days after putting the PM in, the pacing was estimated
at 5.1% atrial and the ventricular pacing was 59%.
Shortly after that visit, I developed atrial tachycardia and so was started back on Metoprolol which I think accounts for the big increase in Ventricular pacing two weeks ago.

It took me about 3 months after having the PM put in, before I started to feel really good. I think having several different arrythmia pop up to sort out, may have slowed down how well I felt. I also have R.A. and that always complicates things for me too.
