Pacemaker battery

I seem to be the only one concerned that my battery depleted 1 year in 4 months.  My pacemaker is only one year old!  Seems strange to me.  Wouldn't you be concerned?

It is what it is. Sure, something is wrong but it's not a huge problem. Just fix what's wrong and move on.  Did they tell you what the problem was (is)?

Don't pay any attention to that number until you get under 2-3 years. Until then it's just a guess based on the current settings. Every time they change the settings, the estimate changes. They tend to make a lot of changes the first few visits so I would expect the number to vary greatly. It'll level out, but even then it's still just an estimate and it gets more accurate as we get closer to replacement. 

You might want to ask if your leads are in a good position. My money's still on changes in settings, but if a lead isn't in a good spot it's going to take extra juice to make it pace which will deplete the battery faster. 

Btw, replacements are a piece of cake. I'm on my 5th. If I get an early appointment, I'm home fixing my own lunch. Last time, I ate, took a nap, then worked a few hours. 

Thanks all!

I’ll calm down now.  I have a doc who doesn’t communicate with me :(

THAT'S a real problem. If that is really how you feel, it's time to find another doctor. Seriously!

Me too

Just had a replacement in November.  I'm down to 3.2 years already.  Appears my RV lead is requiring more and more voltage.   They beleive it is eather a lead issue or my cardia sarcoid kicking in at that area.   They will just keep checking.

Yours could be just settings.   All you can do in wait and see.   Like someone said above it's easy to change out a generator.

I've learned to doesn't pay to worry, just forget and get on with your life.   Easier said than done.

Short time

At my first 6 week check up I was told my battery life was down to 2.2 years. They adjusted the settings and it became 9 years, a vast improvement.  I was going to ask them if I had a Walmart model rather than one from St Jude.

Too funny!  I needed that.   Thanks!

Finally got a response from different doc

There is an auto adjustment feature on the device which adjusts the output to the lead to the left ventricle. The amount of energy needed to capture the left ventricle has increased a bit over time, and the device gave a more prominent increase in output to have a good safety margin. The device has already been adjusted to minimize that increase, but still have some safety margin, so the reprogramming already done should fix this. The return visit at 3 months is to be sure everything is stable with the lead, as well as with the automatic adjustment feature. If the automatic adjustment feature is still more enthusiastic then we would like, even having been turned down, we can turn it off to preserve battery, but then the output will not automatically adjust if the lead changes further. It's weighing pros and cons of using the feature.

Guess I’ll know more in 3 months.

new battery, no.

No that wouldnt worry me at all.  Ignore the battery life estimate until it gets down to the last year or last few months.  


Likewise if they tell you up front it will last for say 13 years and it lasts for 9...oh well...No worries there.

Battery Capacitator

Hi Butterfly,

Just in case you have not been informed:

Both Medtronic and St John had battery failures in some models.

Batteries drained prematurely because of damages to device capacitator.

Capacitator can crack or suffer an electrical short.

Medtronic had issues with their Azure, Astra, Percepta, Serena, and Solara models.

Medtronic problems occurred within 7 months while St John failed within 24 hours.

But yours failed after more than a year, so I don’t know what gives.

Current pacemaker batteries nowadays have life span of 6 to 15 years.

If you haven’t done so, ask your cardiologist to replace battery.

Ask your doctor about new models that use new improved capacitators.

Personally, I’ve had my Medtronic device for 5 years and have about 4-5 years of battery life.

I hope this helps.

A pacemaker completely solved my problem. In fact, it was implanted just 7 weeks ago and I ran a race today, placed first in my age group.
