About This Quiz & Worksheet

Test what you know about the effective refractory period of the human heart. Answer these multiple-choice quiz questions on topics like the 'resting' phase of the action potential cycle and an ion that's used in depolarization.

Quiz & Worksheet Goals

You'll be quizzed on these areas:

  • Muscle contractions of the human heart
  • Whether or not a second depolarization can happen during the refractory period
  • Ways to lengthen the refractory period

Skills Practiced

  • Reading comprehension - make sure you know the most important information from the lesson on the refractory period of the human heart, including the ion that's used in depolarization
  • Knowledge application - use your knowledge to answer questions about the 'resting' phase of the refractory period and the best way to lengthen the refractory period
  • Information recall - access the knowledge you've gained regarding the way muscles contract in the human heart

Additional Learning

To keep learning about the human heart, you can review the lesson named Effective Refractory Period: Ventricular & Atrial. These points will be explored:

  • Effective action potential
  • The resting membrane potential
  • Plateau stage
  • Atrial and ventricular effective refractory period
