Micra Leadless Pacemaker

Hello, I am new to this site. I am 26 and have to get a pacemaker for intermittent complete heart block, pauses, and near syncope. My doctor wants to place a Micra next week, but I called my insurance and they will not pay for the Micra because it's "investigational". Are there any other "young" runners here who also have a pacemaker? Have you had any problems with the leads? Thanks!

IMO, the Micra pacemaker isn't the best choice for heart block. Perhaps that's why your insurance company classifies it as experimental. There hasn't been one for HB very long.

I would be hesitant to get a micra because

- there are no long term studies on what happens when it's time to replace them. You will go through quite a few in a lifetime. Right now they say they will leave micra in when it's time to replace. They're super small, like a grain of rice sized, but put 5 or 6 of them in there and it might get crowded. 

- with av block, it's possible to eventually need both leads and micra is essentially one lead

- not many doctors are set up to program them yet so you'll be limited in follow up care. That's fine now, but what if your doctor retires or you move or you decide to switch to another practice. 

I got my first at 27, two lead, also for heart block. That was 1994. I had one lead replaced in 2010. 15 years is average lead life. My other original lead is still going strong at 27 years old. 

I run and do Crossfit, hike or ski most vacations, love to kayak and do ropes courses, so I'm pretty active. I've never had a problem with the leads. My box is buried a bit, under the pectoral, so it doesn't get in my way when I'm working out. 

And, turns out I have some sinus issues that were masked by the heart block. With heart block, our pulse is totally random, unrelated to what the atria is doing. Once I was paced and the ventricles were suddenly beating in sync with the atria, we found I had a few things going on with the atria also. That's not exactly normal, but it makes me appreciate having that second lead because it was just a matter of adjusting the programming and I was good to go. 

If you have any other questions about being active and paced long term, ask away.  

Extensive research on Micra AV and limitations

I've done extensive research on my Micra AV. And the limitations are interesting. Feel free to DM and I am happy to help

I wasn't really self-conscious about it. I didn't even know I had one until around six or seven years old. I just thought I had a rock in my side.
