[@karlysovereign3492]

Does anyone else listen to Dr. Campbell and feel instantly calm and genuinely interested in whatever content he's talking about? So grateful for him!

[@AfridiZindabad]

He answers all the questions in his lectures, that I had which were tripping me up (so I couldn't move on mentally to the rest of the chapters).

[@carolyn3746]

Absolutely! Studying my ALS2 was less stressful thanks to this amazing Dr.

[@LaSorciereFeuillue]

Ditto!

[@YSC2013]

Karly Sovereign I do too

[@YSC2013]

He sure is wonderful teacher

[@jeanm3616]

I only now, in 2023, watched this stunning lecture. Better than any of the anatomy semesters I endured. I thank you, Dr. Campbell, for sharing your knowledge with ALL of us. I have been enjoying watching your posts for only a few years, having missed this particular one. Again, many thanks sir.

[@TracysavedbyChrist]

Ditto. Just stumbled upon it and first thing I saw was no glasses.

[@shabnumrashid5240]

one of the best teachers on KZbin hands down

[@qazizahor7080]

Hands up

[@jemmya2796]

100%

[@muhammadwajidmunir]

Dr Najeeb is also one of best

[@hakosupra7550]

Can I just say this is absolutely astounding. 6 lectures worth of learning objectives covered in 3 videos so far, I can’t thank you enough Dr Campbell

[@collywobs]

Yes it is his calm articulate voice.After listening to him I feel quite relaxed and refreshed. If I was a patient of his I could face anything as long as he was there to explain the situation. I entered Medical School 50 years ago,I’m 73 now. I just love listening to these talks.

[@paulaswitzer2095]

I "heart" you!!! Thanks for being a teacher instead of a presenter. Most professors etc just present the material instead of teach!!! None of us learn from just a lecture.. No one really pays attention... I cannot wait to watch the rest of your videos.. !!

[@qazizahor7080]

I heart you too

[@randomperson537]

I agree. Dr. Campbell is an excellent teacher.

[@CinnamonDelight-xb8pl]

Thank you for teaching so competently.

[@lyetaherb4703]

That's wonderful. Because these Bio prosecutors today are full of Malarkey. They don't have the first clue about teaching a subject! Straight TRUTH!!!

[@aazamkhan8681]

I also

[@sansamman4619]

When I usually see a smart person I feel guilty and think to my self “I have been wasting too much time, I should be smarter!! “ which stresses me out and doesn’t help. But when I see you I feel like you are telling me “Hang in there buddy, just give it your all” which encourages me to study more. I love you doctor, you don’t know how much you have helped me

[@steveholmes161]

I feel like when I’m listening to this, he’s talking just to me. It’s as if we’re having a conversation. But I’m being quiet for about 20 minutes or so. It seems so personal and comfortable. Excellent!

[@patricesekanyambo284]

Teaching is a gift indeed not just the level of knowledge. You can even see how passionate Dr. John is, just wonderful . God bless you Dr. I do not know why it took me so long to find you on here.

[@adrimontemayor3234]

I recently started working as a Spanish-English medical interpreter. Your videos have been an amazing tool to familiarize with vocabulary. Thank you Dr. Campbell.

[@rosegallus4048]

I can't thank you enough! I have never been able to properly understand the electrical conduction in the heart, until today.

[@rasikakurupitage4100]

I accidentally found this video of this great pleasant person Dr. Campbell and so grateful to him. I got a very wonderful worthy knowledge about the cardiovascular system. Very understandable. Many more thanks to you Sir ❤️💙😘. Have a long life to teach us more.! 💐🌻🍄🌺🌹🌸💮🌼💓💛💚💜

[@chileuwachidozie7496]

I am not a student of medicine, I am a first aider. I can now explain this to a medical student while sleeping...thank you Dr. Campbell.

[@martipascual7413]

Thank you so much! I worked as an RN in the hospitals for 10 years then stepped out of my career to be a full-time mom for the last 12 years. I found your videos while I was looking for ways to refresh my memory before heading back into the workforce. How I wish I would have had access to your teachings while in nursing school over 20 years ago. Your explanations are so basic and thorough, that I'm not only remembering, but also learning new information. You have a way of speaking that makes everything easy to understand.

[@constantejimofor9213]

I've Listened to Lecture 1, Lecture2 and now lecture3. Listening and learning from Nigeria. 🇳🇬 There's a sense of soothing serenity, tranquil, and quiescence, that follows your lectures. Feels like a teaching Made from heaven. Who else agrees? ✋🏼

[@patiencekalua5650]

My goodness I've heard this cycle explained so many times and NEVER comprehended anything really but now i can actually explain to someone without looking at the notes. Thank you Dr Campbell you're God's send and you're helping create future Drs and Nurses

[@heatherpeterson3610]

As a homeschooling family...we thank you for sharing your gift of teaching. You are our favorite teacher. It is so easy to understand you.

[@kimberleydsouza9813]

I honestly used to HATE to study about the heart but thanks to you and your amazing videos I now find studying about the heart so interesting!!!!! Thank you so so so so so so much. Please keep making amazing videos like this. Much appreciation and gratitude. xx

[@Zazezoo]

I used to Hate it too, and found it complex and boring. Now I'm enjoying it so much, cos everything makes so much sense.

[@nilanabijan9705]

I swear to God me too! after his explanation I used to love HEART

[@mr.potatoseedidk1129]

This doctor is the best. I am now starting in nursing and reading the books I was having difficult in understanding but when I listen to these videos from this doctor if really feel calm and I pass my exams. He is the best.

[@kandicekrucina6988]

I just want to say, you have the BEST videos!! The only way I completely understood the heart was by watching all of your cardiovascular videos! THANK YOU A MILLION TIMES!! 🙏

[@lberry750]

This was the best explanation of the cardiac electrical system I’ve heard. Thank you, Dr. Campbell.

[@abcindyefgh_4569]

I am currently taking an Introduction to Cardiovascular Nursing course, which made me understand our lessons more. Thank you so much.

[@ms-jm8jl]

As a layman, I did know something abt the heart and how it functions. After listening to your lectures, I'm amazed at how you've simplified the way the heart functions without compromising on clarity. I can listen to your lectures over and over again and always learn something new. Every time I listen to a lecture, your passion for the subject makes for delightful listening. I only wish I had found you sooner. Thank you, Dr.Campbell

[@ingriddawson4102]

Incredible. This man is a wonderful teacher in a fascinating and complex subject. Thank you Dr. Campbell.

[@tammy6973]

I'm now convinced beyond, I had never understood this before but now I've. I'm humbled. Congratulations to Dr Campbell God bless you.

[@dopiaza2006]

As a non medical person with a heart attack 6 years ago, this has been the best video I've seen yet to explain why I get PVCs, and most importantly, why they aren't as dangerous as they feel. I wholeheartedly (!) thank you!

[@jackedwards9790]

thank you for keeping these videos up even years later, amazing work, truly a great professor.

[@jilldelzer9456]

This is an excellent presentation and well explained. I appreciate your method of teaching and find this to be so helpful!

The best physio explanations ever, thank you Dr. Campbell!

[@narelledarby1493]

What a fantastic presentation of the cardiac conduction system. Taught me more than any of my text books or lectures in my nursing degree

[@mightymagnum8811]

How can anyone believe this system evolved? It's incredible!

[@jaddapuss]

Best explanation I've seen ever! Even an idiot like me can grasp the essential info.....Thank You so much.

[@Campbellteaching]

+jaddapuss If you have understood all of this, trust me, you are not cognitively challenged. Physiology is difficult and highly conceptual.

[@jaddapuss]

+Dr. John Campbell Thank you so much, I was even dreaming about pulmonary veins last night!

[@leebosward7699]

My lectures for physiology are almost pointless! Its all about the ego of those lecturing not the students. Your presentations are an absolute life saver. I got full marks on the quiz thanks to you!!

[@lindanambahu1142]

As a med student that doesn’t really like Cardiology😬, I am grateful for these amazing videos. Thank you so much Dr💯

[@user-kh2ud4mk8v]

You are anointed to teach us. Once again, thank you. Kindest regards, Leta Pasternak
