Welcome to Part 2 of Rhythms!
Hopefully you've made it through the sinus and atrial rhythms in Part 1 of Rhythms, and you're ready to continue our way along the conduction system. In this section, we will review AV junctional rhythms, ventricular rhythms, and very basic pacemaker rhythms. Two full sections are dedicated to pacemakers later in the course, which will help us make sense of pacemakers and understand how they operate. The end of this section will mark a BIG step forward in our learning journey. It may feel like a lot of work, but it will be worth it. Remember: rhythm analysis is critical in interpreting any ECG so stay focused during this section...and have fun!

Quiz-Gated Learning: After completing a quiz, content related to that quiz will be unlocked. Each lesson will have at least one lecture and practice mastery questions related to that topic. Note that some lessons may have two videos -- one lecture geared towards the beginner that is learning rhythms for the first time (or just wants to really get it once and for all) and another lecture geared towards reviewing key hallmark features and pearls to diagnose each rhythm on a 12-lead ECG. The latter serves as a great review for the more experienced interpreter. Both will complement each other and solidify concepts even more.
