What Do You Know About Electrophysiology? Trivia Quiz

Electrophysiology is the division of physiology that studies the electrical properties of biological cells and tissues. It entails measuring voltage changes or electric current on single ion channel proteins or even the heart. On this quiz, you will be asked various questions related to the heart and how to read it. What do you know about electrophysiology? Take the quiz and find out. Even if you think you can’t answer the more challenging questions, this quiz will give you a change of heart.
