There is no teaching component to this lesson. There is only a practice session. These practice ECG's are all abnormal, so waveform identification might be more challenging compared to the previous lesson. You need to complete 8 cases and score 70%.
We appreciate this is a lot of waveform practice. If you are struggling with this skill, you will likely become frustrated with future lessons and diagnosis practice in later modules. It is worth your time and effort now to learn the abnormal waveforms.
