12-Lead EKG Introduction

A sequence of videos designed to create a foundation of understanding of the 12-lead ECG in pre-health profession freshman and sophomore students. This video should not be considered clinically relevant, rather I hope it serves as a basis for understanding the biophysics of ECG recordings so that the interested student can use it to further develop their understanding of ECGs. Relevant topics covered will be an introduction (Part 1), diagnoses possible (Part 1), cardiac conduction cycle (Part 2), Einthoven's triangle(Part 2), how ECG leads detect the voltage changes in the conduction cycle (Part 3), a basic understanding of leads I, II, and III, augmented leads (Part 4), QRS axis (Part 5), Precordial leads (Part 6), and a return to diagnoses using http://www.ecglibrary.com (Part 7).

I guess the main answer is in my profile picture; while I feel that providing open education content is a noble goal, it takes away resources from those two little girls. While I am an asst. professor, creating these videos is ancillary to my teaching duties and therefore it comes out of my own time. And, I could buy a lot of soccer balls and books for what an expensive microphone and an HD camera costs. I have them now but I have focused on new videos. Please tolerate my learning curve.

mate you are such a champion - to all the whiners shut the fuck up. This guy singlehandedly addressed the problem with virtually all ECG tutes; they don't explain HOW they work, they just jump to the waves etc - thank you so much!

123rypems, I used the headphone and his voice came out clear. At the onset, his voice is probably a little scratchy but then I believe he apologized for it. Nevertheless, it is better to use a headphone to listen to his lecture.

123rjpms, hi!

The sound is not that loud but it is understandable. He is saying what he is writing so the notations are not a problem even if hard to read as you said. If you listen close enough, there is no need to struggle to read the notations because he is verbalizing them as well. These are not "short failings" on his part and it is easy to understand him.

Hennagerdj, thanks for your effort to teach via the video outlet. You have the gift of teaching. Thank you.

Thank you for all your time & effort and contributions to learning. Your videos are a great supplement to Guyton's Physiology

Thank you Professor, what a great way to spend my Friday night that I needed to study cardio for my exam this week :) You really made it come alive for me! Im a nursing student and while I had to go in a quiet room to hear it really well, but believe me, it was worth it! Thank you for taking time to do this :) I have watched a whole bunch of your videos this evening.

Over and over these videos have great content, but very poor audio quality and hard to read notations. This guy says he is an instructor, so it is difficult to understand why he does not correct these short fallings.
