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).
But are these types of relationships really so hard? Or, as a recent study suggests, does absence truly make the heart grow fonder? According to some estimates, up to 75% of college students have engaged in a long-distance relationship at some point, and roughly 25% to 50% of them are currently in one.
