lp.interactive... - FREE CARDIAC CYCLE GUIDE
We all know that the heart beats. We don't even need to think about it - it just happens. But, there are many details that need to come together in order for it to happen efficiently and effectively.
In this videos, Leslie goes through the concepts involved in the cycle, explaining the phonocardiogram, electrocardiogram (ACG/EKG), ventricular volume and pressure, atrial pressure and aortic pressure.
Enjoy!

You just explained basically 30 pages of reading in my A and P book in a 13 minute video. You are the man.

@alverarobinson9276 7 лет назад

He really is the man lol. I'm so beyond happy I bumped into his videos.

@georgyorgy2 8 лет назад

My teacher spent like half an hour trying to explain this and failed miserably, but you sir, were successful in less than half the time. You're the man!!

@bigdaddylee8019 8 лет назад

this professor is a heavenly sent for all medical students.

@angelapockat6696 8 лет назад

This is one of the best videos on the cardiovascular system out there. Well done

@sageforcast 5 лет назад

Made an account just to say thank you. That made my life easier.

@kasnimalan9628 5 лет назад

I’m way too lazy to listen to someone explain BUT this guy is a legend. He broke it down, explained well. Watch it.

@Splinter4077 11 лет назад

My heart has gone through so many rhythms since watching this video. Makes you think a little!

@linzahashir7099 4 года назад

I have no words...just THANK YOU SIR!!!

@ladynottingham89 10 лет назад

You are a great teacher. It is truly an art to be able to teach to others!

@whisperingsage 4 года назад

And some teachers don't care if you understand, they just want to dazzle their students with their intelligence. Thankfully, there are fewer of those these days. AT least I am lucky.

@misskittani 10 лет назад

You have helped me a lot during my physiology course. A real treasure, I just love you

@canpeanionut 11 лет назад

I can't say anything more than: "Respect." . I do respect this man for what he is doing and I think we all should.

@regardsrhi 13 лет назад

Was searching for lots of videos to explain the cardiac cycle, this is the best one so far! So detailed and you accent is lush :)

@melissabarrientos9785 7 лет назад

I have studied medicine for 8 years and this is by far the best and easiest way to explain such an important subject! thanks to u Im confident with this subject for my step 1 :)

@robertp5615 9 лет назад

Great video! thanks for the explanation. One thing though, the 4th sound has to do with the active filling of the ventricle (due to atrial contraction), not the filling of the atrium. Just like the 3rd is the passive filling of the ventricle, the 4th is the active. Thank you again for the great video!

@InteractiveBiology 12 лет назад

@MaficSun You're welcome! Stay tuned. We have more Biology videos to be uploaded very soon! :)

@jessienguyen1193 7 лет назад

Im P1 student, this part of lecture, my professor made it so complicated and confusing. I was struggling w it. I went through couple videos on youtube, but yours are the best. I love the tempo, clear explanation, visual aid you show. Thank you so much!

@01rai01 10 лет назад

I can confidently say that the reason I ace the pressure-volume curve question on my exam was because of this video. I watched the vid about 4 times and had like Leslie's voice in my head while doing the question. Thanks for all you videos.

@turbotysen 8 лет назад

Helped me understand WAY better. My teacher brushed right through this part of the lesson so fast, it was hard for me to retain all of the useful information that I needed. Also just looking it over in the book trying to understand it by yourself is kind of challenging. Much thanks and appreciation!

@Debster675 11 лет назад

I've learned more from you in just one video than I have from a human physiology class in a four year university. Thank you soo much! :D

@bams6920 7 лет назад

You are going heaven because of this video. I know you heard this hundreds of times but this is the best explanation of the graph so far. THANK YOU SO MUCH

@madisonjones9137 2 года назад

What took my professor 2 hours to explain, you answered in 13 minutes. THANK YOU KIND SIR!!!! Saved in dental school

@InteractiveBiology 2 года назад

Glad to help 👍

@allimeo1 10 лет назад

You are a lifesaver!!! I plan on using all our videos to help me with my physiology class. (My professor assumes we already know all of this)

@MaficSun 12 лет назад

Remember walking into class late with all this stuff written on the board. i was so lost... not anymore. thanks a bunch.

@samirpatel5786 7 месяцев назад

Many have stated it, but I just want to reiterate, you sir are a great teacher. Took an absolutely brutal topic and made it cake. Thank you so much for that!!!

@courtneywestbrook67 11 лет назад

Hey, Leslie. I'm a senior in college and am in Animal Physiology this semester and it's killing me! Thank you so much for taking the time to post all these videos. They are so helpful!! I just wish I had discovered these earlier and I'd probably have an A and not a B! :)

@T2star 2 года назад

After perusing many cardiac cycle videos on here, I can say this is the most succinct and digestible one. Some videos on here have big errors so be careful. This video is what you need!

@InteractiveBiology 2 года назад

Yayyyy, Glad to hear that. Did you see my recent video on the cardiac cycle? I decided to revisit the topic here - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KmNHqqrFqG8.html

@marygracerafisura7475 10 лет назад

I LIKE THAT YOU ARE COMMUNICATING IN A SIMPLER WAY FOR A PERSON LIKE ME WHO HAS A MIND THAT CAN ONLY RETAIN WHEN YOU EXPLAIN IT LIKE A CHILD. LOL.JK.. LOVE THE WAY UR EXPLANNATION. KEEP BEING A GOOD TEACHER....DON'T GIVE UP ON UR STUDENTS EVENTHOUGH IT FEELS AN INTERNAL LIFE OF TEACHING...DON'T LOSE THAT PASSION

@thegarbageman21 11 лет назад

Yes you are correct. The ventricle AV valves are open and at ventricular low pressure (after relaxation) so the blood will pour in from the atria. Remember you have all that blood coming into the atria from the Vena Cava which makes atria have more pressure than vent. In young people ventricles actually get over 80% of the blood before the atria contract. When you get older however the ventricles get stiffer so that atrial pumping mechanism becomes more important to squeeze that blood in.

@PoorAmerican 8 лет назад

Got an exam on this in a few days and your videos will get me that A. Thank you so much for making these. You are incredible.

@oliviaalladaye6592 8 лет назад

It is really the type of processus that needs to be broken down ... and you do it very well, slowly and clearly. Thanks so much for your help !!

@gigilo0910 11 лет назад

I think your speed is great. It allows me time to digest the information. Great job!!

@InteractiveBiology 12 лет назад

@Neopluto We'll see what we can do. :) Thanks for watching though! There are more videos you might want to watch from our Biology website. More will be uploaded so, please stay tuned!

@tererachie 9 лет назад

It was definitely intimidating at the start but it's amazing how it all makes sense at the end of the video. Thank you very much

@hesc2139 12 лет назад

No other video or college professor has been able to make this any more clear for me...and you did it in less than 14 minutes! I wish I would have found your videos earlier! This video makes the whole process so easy to understand. Your videos make an excellent reference. Thank you!

@nickcolejackson6884 9 лет назад

I want to thank you sooooo much for making this process as easy as possible. You have helped me with several topics and I really appreciate it. I needed help with this section because it is so many sections and it has a lot of details. I have a good understanding now of what is going on after many times of watching. THANK YOU SO MUCH FOR YOUR HELP!!!

@nabilbarsoom7935 11 лет назад

thank u indeed , an easy and simple way of teaching , but wishing a richer scientific subject .

@dawoodali4605 2 года назад

This video is 10 years old and you are still replying to comments, you are a legend!

@InteractiveBiology 2 года назад

The purpose of the channel is to help people understand biology. So I try to do what I can. I can't get to EVERY comment, but I try to offer value when I can.

@tehyonglip9203 7 лет назад

it was so intimidating when i first saw it, but now it looks much better, free subscription for you

@assemubigaliyeva5872 5 лет назад

Out of all the videos I've watched on youtube to get this topic you eased this whole process for me. A HUGE THANKS, DUDE)

@Missprak 11 лет назад

Excellent teaching of the Cardiac cycle, may God continue to bless you with your great generosity

@catherineava7937 5 лет назад

You are awesome! I wanted this for my physiology essay.BIG hug for you. You explained it million times better than the physiology textbook.

@burninhelenprd 11 лет назад

Thank you SO MUCH for these videos, I have a particularly inconsistent and confusing teacher for physiology who is unable to organize the material in a way that makes sense and is cohesive. I wish I could have paid you the tuition instead as these videos are how I am really learning. I wish all teachers could teach the way you do. you are amazing! Truly, from the bottom of my heart, thank you!

@jyothsnab.k3928 5 лет назад

@michaelgernatt5621 7 лет назад

This is hands down the best video I have seen for explaining this process. Thank you so much!

@annetteasbury7415 10 лет назад

Thank you so very much for this video sir! We had this same diagram presented to us in our NP advanced pathophysiology/physiology course and the instructor just blew through it as if it was something we had been previously exposed to. The only thing that was clear was that it supposedly represented the cardiac cycle. Thanks to your video I can now go back to the diagram and actually UNDERSTAND what's going on. Thank you so very much!

@gautamidusane5025 4 года назад

@InteractiveBiology 13 лет назад

@TimmysMummy Ouch, sorry to hear that. Being nervous definitely impacts the way you do on an exam. But over time, it can get better, especially if you study EXTRA hard so that you are extra prepared.

@Nanomachines5on 9 лет назад

Thanks for walking through this. Saved me a lot of study time.

@ahmedbass1257 8 лет назад

Thanks man am an mbbs uni student and am studying the cvs module now this diagram was getting on my nerves i swear but u man u deserve a medal for that video physiology of the cvs is in my pocket now :D thanks brother ❤️

@MentosGumie 10 лет назад

i saw this diagram in my book..and it look like a foreign language, and then i watch ur vid, and IT ALL MAKES SENSE!!! This forgein image nows look more like a map of the heart atrial & ventricular contraction!

@ManSirMr 10 лет назад

Great job on explaining the cardiac cycle. I was worried about learning the wiggers diagram but now with your help I feel I understand it better.

@sarah5578 4 года назад

@sostoked07 7 лет назад

Thank you for this!!! I know you've just recently let go of this channel (so bittersweet but I wish you the best!), but I'm still sending you my thanks. Med student here, and I'm quite intimidated by cardiology. Thanks to your amazing video (and really friendly narration), I feel much more reassured :) May more good things come your way!! :)
