Guided Learning: Abnormal Cardiac Rhythm

This guided learning topic assumes the student is already knowledgeable of the content associated with the cardiac electrophysiology guided learning topic. The student is encouraged to go not only to the initial link associated with each learning question, but also to use embedded hyperlinks to expand upon the physiological concepts associated with the question.

Linked Quiz Questions

At the end of the guided learning questions, there is a link to an external website (testmoz.com) that has multiple choice and true/false questions associated with the guided learning. When the quiz results are given to the user after taking the quiz, links are provided back to specific cvphysiology.com pages to assist learning. Users need to register (free) on the testmoz.com site to access the quiz questions for the tutorial. No personal information is available to cvphysiology.com apart from the user provided login name and analysis of user performance on the quiz questions. This feedback is used to improve cvphysiology.com content and quiz questions.

Guided Learning

1. What are arrhythmias?
2. Define each of the following arrhythmias:
   1. sinus rhythm
   2. sinus bradycardia
   3. sinus tachycardia
   4. sick sinus syndrome
   5. atrial tachycardia
   6. atrial flutter
   7. atrial fibrillation
   8. junctional escape rhythm
   9. AV nodal blocks – first, second, and third degree
   10. supraventricular tachycardia
   11. ventricular premature beat
   12. ventricular tachycardia
   13. ventricular flutter
   14. ventricular fibrillation
3. How can altered automaticity and conduction cause arrhythmias?
4. What are early- and delayed-afterdepolarizations, and what can cause them?
5. What are ectopic foci?
6. Under what conditions and by what mechanisms can a non-pacemaker cell become a pacemaker cell?
7. What are reentry currents, how can they lead to tachyarrhythmias, and how can changes in conduction velocity and the relative refractory period either precipitate or abolish reentry currents?
8. What are the hemodynamic consequences of arrhythmias?
