10. Be able to define the five steps necessary to interpret cardiac rhythms.
11. Be able to calculate heart rates by three different methods.
12. Be able to list the qualities required for a sinus rhythm to occur.
13. Be able to define Sinus Tachycardia, Sinus Bradycardia, Sinus Arrhythmia.
14. Be able to list the qualities found in various abnormal cardiac rhythms, and identify each abnormality in the rhythm strip.
