Never have I been taught ECG in my five years of medical school like this. This is easily the best lecture on ECG basics by far. God bless you sir.

After almost 10 years of studying medecine, NOBODY beats this Guy. He is a true Hero

[athuddriver]

I'm a 68 year old dude wanting to understand some of my heart rhythm issues. Call me an enginerd that loves understanding the technicals of what I'm looking at. Kinda tired of the cardiologist not helping me truly understand what we are looking at. This presentation really helped me understand how my Kardia Mobile works. It also lets me have a greater understanding of my doctor's 12 lead machine read out. It isn't going to make me a medical tech nor a cardiologist but it levels the playing field to talk intelligently with my cardiologist. As a person that managed training in a technical field (air traffic control) I applaud your use of visuals, retracing concepts and building on them from start to finish. WELL DONE!

[christiandad]

Seriously.... it's like having your own private tutor. Whatever instilled in you to gift your time and knowledge to the rest of us for FREE!! I thank you. God bless mate. Much love from Australia.

If there was a Nobel prize for education, it would have to go to Zach and Ninja Nerd team (every year).
One of the most useful channels on youtube ever. Thank you for all your work <3

[yezzypops]

Zack makes EKGs bearable. I learned a lot tonight, especially that, "The left ventricle BE THICCC." I will never forget that, Zack. Thank you, sir.

[tarunmahananda]

You're creating thousands of doctors with your each lecture .
Thank you so much professor

[queteimporta]

It has been 3 years and I am still impressed on how simple this man made the ecg.

[juliapieper]

Zach said one sentence, that really stuck with me throughout the whole video: "I got you". And that is exactly it. Whatever the question or problem in understanding you might have... Once you finish a video you feel like all is crystal clear and easy. Thank you so much for that passion all of you have at the Ninja Nerd Team!

[serinegs]

You are incredibly pedagogical, you are meant to do this, this is your vocation and what a vocation ! ...thank you so much for sharing with students all over the world especially those who don't have access to good quality courses and can't provide enough books to build an overview ...you have no idea how much they are grateful <3, i hope i can feel so helpful explaining some thèmes for students that study med in French

[floriankordowske]

How in the world did this dude just manage to explain EKG a thousand times better in on hour than any professor at medical scool did in 2 years… thank you so much

[kipkipour]

It's past midnight...
I am still reading for my exams...
I am tired.
Thank you for your help all those lonely nights, NINJA NERD!!!

[gegeeh.a]

I have never been more thankful for an education resource in my entire life! thank you so much. It's because of how clearly and wonderfully you explain things that I am able to find joy in continueing my degree!

[rebeccahodges]

I have been a nurse 25 years and a nurse practitioner 9 years. Your ability to break things down and teach them is gift beyond words. 25 years and I actually now understand how a 12 lead EKG really works. I am so grateful for you! You have a fan and follower for life. Thank you for being a phenomenal teacher.🥰 You make learning FUN.

[jaimiedickinson]

I can't express how grateful i am for you professor murphy!! I am a year 4 med student and this is my FIRST time - my FIRSTTT time - actually understanding how the ECG actually works. 20 minutes in and I KNOW that this is the video that is going to save my ass in clinical years. Thank you so so much!! Hands down the BEST ECG video out there :) When I earn my first paycheck in the future, I will be sure to donate it to your patreon!!!

[soniamejia]

I see a day where you’re going to have 10 million subscribers! The best channel!

[ReemHamasha]

You're truly gifted Zak.
The goal is to excel at an aspect of my life the way you excel at this.
Thank you big time

[delrosariorose]

Thank you for sharing your gift of teaching 🥰🥹 This is actually my FIRST TIME understanding EKG and I just graduated from med school 🫠 You’re better than most of my professors. May God bless you! THANK YOU. ❤

This man is a genius, and I wish I had this level of refinement in my thoughts; he never stumbles and remembers all the terminology and the details involved with every term or concept. Crazy.
