If you are on Facebook this is a great ECG resource to check out. Lots of video and graphics to help you with understanding ECG’s and over 95,000 members there. If you do join the page do me a favor and let them know that EMSSEO.com recommended the page. It really helps spread the social media love. Check it out at the link below.
I also think you will find many advanced ECG concepts there. So, before you get too deep into that be sure to understand the basics of ECG’s and rhythm strips. One resource I always recommend is the Ultimate EKG Guide. This guide is really a go to resource for grasping the basics of EKGs and a great tool to refresh for exams.
