Cardiac Arrest...?

“arrest”の意味は「逮捕」だけではないことを知りました。

The other day, I heard the word cardiac arrest on the news. At that time, I had only known arrest to mean that the police take a person who is believed to be guilty of a crime into custody. Therefore, I could not understand what it meant, although I was able to guess it was something related with heart disease because cardiac is a word connected with heart or heart disease. Then, I looked up arrest in the dictionary, and found out that it also means to stop or interrupt something, and cardiac arrest means the stopping of heart activity. It is always nice to learn new meanings of words that I already know.
