ECG Quizzes & Trivia

The word electrocardiogram doesn’t have you ducking your head in a room full of strangers. Rather, the moment you hear it, you find your voice. Not only can you tell that it records the electrical activity of the heart but you can explain how the heart works and how the electrical impulses it produces are detected by an ECG. You can also explain the various body parts where electrodes are attached to, the heart defects it can detect and its limitations.
 
You are aware that ten electrodes are required to produce 12 electrical views of the heart. Do you know what Bradycardia means? Can you define the term Tachycardia? Do you know that there can be delays in the transmission of electrical impulses within the system? Do you know what happens during an ECG? If you know the answers to such questions, take these quizzes to test your ECG knowledge.
