9-month-old with recurrent episodes of supraventricular tachycardia despite medical therapy

Case

Hi, I’m calling about a 9-month old infant, that you follow, with supraventricular tachycardia. She presented today after the parents noted that her heart rate was elevated to our urgent care. Heart rate was steady at about 220 bpm and mom said they first noted it about 2 h ago. We were able to apply ice to the face and forehead a couple of times that seemed to slow it down but really didn’t break it. Then as we were getting an IV, the tachycardia broke. Right now, she looks great, comfortable, and has a heart rate of 120 bpm. She is on propranolol and mom says she’s been getting her doses. I’d like to send her home but wondering if there is anything you would like me to do?
