My sister in law is almost 37 wks pregnant with first child. In her last check, the midwife picked up the occasional missing heartbeat in the baby - think it's called arrythmia. A trace at the local hospital has just confirmed this. I've just googled this and found that it's actually quite common and that the problem usually resolves itself. However the hospital are doing another trace and she's seeing a cardiologist nxt week so they're obviously taking it seriously. She also has low levels of amniotic fluid which I'm not sure is connected, but I thought I'd put the feelers out on that one too. Any advice/ similar experiences? Sister in law is obviously distressed.
