In medicine (obstetrics), cardiotocography (CTG) is a technical means of recording the fetal heartbeat and the uterine contractions during pregnancy. The machine used to perform the monitoring is called a cardiotocograph, more commonly known as an electronic fetal monitor (EFM).
I think the reason why long distance relationships donât work is because of a lack of commitment from both parties and because often the relationship drags on without either person ever planning to move (so no light at the end of the long distance relationship tunnel).
This doesn't seem like any kind of novel idea, but it's such a common mistake that it bears mentioning here. Going on little dates with other people is the easiest way to make your long distance relationship into a series of drunken hate-voicemails, threatening packages and arson attacks.
