Peerless Doctor in the City - Ch. 6

So basically this situation went like this.
Brother: You dare to say that ambulance can't get here fast enough? I will kill you!
Brother: Oh, you are a doctor? Cure her or I will kill you?
Brother: Why are you standing like that? Die!!!

How stupid is that character or author writing it?

From my observation, it's impossible to "hear" her heart beating like that.
