Adenosine is a medicine that can help slow down a fast heartbeat called supraventricular tachycardia. It works by blocking certain signals in the heart that can cause the heart to beat too fast. When the medicine is given, it can make the heart stop for a very short moment and then start beating again at a normal pace. This is one of the longest pauses I’ve seen giving this medication. #adenosine #atrialfibrillation #emergencymedicine #medstudent #premed #nursingstudent #nurse #doctor | Dr. Joe,
