Book excerpt: Use analogies to make basic ECG concepts comprehensible and memorable for your students! The anatomy of the heart is like a house with rooms and doors. The intra-atrial and internodal pathways are like highways. Your students will absorb ECG interpretation like a sponge! This diverting, EZ-to-read approach, coupled with sound educational theory, encourages learning in students who are frustrated by the non-descriptive, formulaic writing found in most other textbooks.
