Interactive Exercises: Cardiovascular
Contains activities related to cardiac labs and diagnostics. From the website to accompany Davis’s Comprehensive Handbook of Laboratory and Tests with Nursing Implications, 3rd Edition.
ACLS for EMTs--basic
This site, while desinged for EMTs, has some interesting skills videos and flashcards that may benefit advanced nursing students and practicing nurses.
The EKG Waveform
I like this site because you can watch the waveform simultaneously with an animation that shows the electrical activity that is taking place in the heart.
