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).
Partners that take active and conscious strives to get know each other will have a more realistic perception of their relationship, and will make their long distance relationships LAST!
