Stray impulse

Hello to you all,
After a recent check up and a "tweaking" by the technician i have had a stray impulse which causes a major spasm in my diaphragm and this happens every night at 5 pm, regular as clockwork. I am fully paced with 3 leads and a medtronic pacemaker.
Any similar experiences out there?

Could be diaphragmatic stimulation + Ventricular AutoCapture or something that checks diagnostically every night.

It sounds like during the day your "normal" programmed setting is perfectly suited to not cause the diaphragmatic stim.

Then @ 5 AM the device runs an algorithm or something to do a self-check. The reason why I guess Ventricular AutoCapture is that it automatically tests capture, so it'll decrement output until there is a loss of capture. I don't know if Medtronic this way, but I do know St. Jude's devices have a "test" pace followed by a very quick "backup" pace while it's determining capture, and the backup pace is programmed to be @ a very high output. That high output, well above your "normal" output, could be causing that stim.

But the above is just an uneducated guess. I'd ask him exactly what changes he made, and mention this. He can always revert to the original changes. Hardly any "tweaks" made are absolutely necessary and can always be rolled back.

I have a medtronic and the same thing happens to me at 1am, its capture management as explained above, ask them to set it late at night/early in the morning so you can sleep through it ..

I too had pain at the same time each day. Had my checkup and now that the timimg has been changed all is well.
They don't tell you much but at least they fixed it for me

Your pacemaker interferes with your electronic scale.
