Hello - does any body know what your ventricular pacing threshold is? My daughter, 12 yrs, has a pm, and she is so unfortunate to have had problems before with her threshold rising until the point of no capture which means that she is now on her 3rd pm in three years. The one she has now is fine, however, we went in for the biannual check yesterday, and her threshold had risen from 0,8 in October 11 til 1,1 now. And I am starting to wonder if this thing may happen again to her - that the threshold will keep going up until there is no capture, and she has to have her leads replaced again. Should I be worried - or I am just too sensitive towards these numbers? The pm nurse was not worried, he noticed the slight rise, but all in all, it was just a small change, he said.
What do you think?

Er der nogen herinde, der er klar over, hvad jeres tærskel er ift pacing af ventriklen? Hermed mener jeg den mængde strøm, der skal bruges for at udløse et hjerteslag? Det er min datter, der har en pm (hun er 12 år), og hun har før døjet med, at hendes tærskel begynder at stige, indtil pm ikke har nok volt til at udløse et slag, hvorfor hun er blevet svimmel, og hun har 2 gange på 3 år fået skiftet pm. Pt har hun det godt, men i går til tjek på Skejby var hendes tærskel 1,1, hvor den i oktober var 0,75 - og jeg tænker selvfølgelig på, om det kan ske igen. Kan I huske, hvad jeres tærskler er - eller er jeg bare for nørdet? ;-)
