The Cardiac Cycle

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]

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

[@deanie54]

THANK YOU I WAS LITERALLY CRYING ABOUT MY PHYSIOLOGY CLASS BUT NOW IM A LITTLE MORE HOPEFUL BRO

[@CariBaez]

i thought i was the only one that cried :(

[@jessienguyen1193]

same!

[@Bilbus7]

Dang I hope you're not my doctor or nurse

[@darklarrie535]

are u a doctor now

[@georgyorgy2]

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]

this professor is a heavenly sent for all medical students.

[@angelapockat6696]

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

[@InteractiveBiology]

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

[@slurpee3113]

Thank you SO much! I might actually pass my anatomy and physiology test tomorrow now!

[@InteractiveBiology]

Woohooo! All the best!

[@fatimahff123]

Passing is shit. HD or death.

[@sageforcast]

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

[@kasnimalan9628]

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

[@InteractiveBiology]

@ToRnAdO0504563168 Thanks for the feedback. Glad you are enjoying it! Stay tuned for many more!

[@canpeanionut]

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

[@ladynottingham89]

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

[@whisperingsage]

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.

[@Splinter4077]

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

[@robertp5615]

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!

[@misskittani]

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

[@InteractiveBiology]

@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!

[@linzahashir7099]

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

[@jessienguyen1193]

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!

[@turbotysen]

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!

[@allimeo1]

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)

[@jessegandy7039]

This is the best A&P teacher on youtube.

[@01rai01]

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.

[@melissabarrientos9785]

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 :)

[@courtneywestbrook67]

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! :)

[@Debster675]

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

[@regardsrhi]

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 :)

[@MaficSun]

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

[@bams6920]

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

[@marygracerafisura7475]

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

[@InteractiveBiology]

All questions are answered in the Interactive Biology forums from now on. Go to the website in the description and then visit the forum. This is to make it as efficient as possible as we have multiple people over there to help answer questions. All the best

[@madisonjones9137]

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

[@InteractiveBiology]

Glad to help 👍

[@PoorAmerican]

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.

[@samirpatel5786]

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!!!

[@tererachie]

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

[@oliviaalladaye6592]

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 !!

[@T2star]

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]

Yayyyy, Glad to hear that. Did you see my recent video on the cardiac cycle? I decided to revisit the topic here - kzbin.info/www/bejne/gZ6xeaSnp6ukfZo

[@nickcolejackson6884]

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!!!

[@assemubigaliyeva5872]

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)

[@LoolJohn]

You are amazing! I am much less overwhelmed now than I was 14 minutes ago. Thanks for breaking this down so well.

[@dawoodali4605]

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

[@InteractiveBiology]

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.

[@InteractiveBiology]

@combymanje123 You're welcome! PLease stay tuned because we have more Biology videos coming very soon!

[@hesc2139]

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!

[@InteractiveBiology]

@viju345 Glad you're finding value in it. Visit our site for more fun Biology videos!

[@BabyCas99]

Thank you so much! I could actually cry tears of joy! I might have a chance of passing my Physiology and Pharmacology exam with 50% failure rate now! THANK YOU!

[@tehyonglip9203]

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

[@PAStudent]

That was the best video I have watched on Wiggers! Thank you!

[@allisondentinger4341]

so much easier to understand now than when my physiology professor explained it

[@ellierebecca1994]

I finally understand it now! Best cardiac cycle video ever!

[@catherineava7937]

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

[@thegarbageman21]

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.

[@786slizza]

im watching all your muscle and heart videos one day before my finals and i must say iv learnt more in these past two hours than i have in the past 4months!!!!! THANK YOU

[@InteractiveBiology]

@xty070 You're very welcome! Stay tuned. New Biology videos will be uploaded soon!

[@mariyanabranzburg8320]

intimidating less but helped me understand better, thank u so much!!!! :)

[@InteractiveBiology]

Glad to help :)

[@justicemunyoro]

useless advert

[@mamadousowe4978]

mariyana branzburg ewcbdyu hello

[@deltraaustin]

Great break down. I was lost in class but now I have it.

[@NYESTRELLA]

I have no words to explaine to you, how mucho you have helped me and continue to do so. THANK YOU VERY MUCH FOR SUCH A GOOD HEP

[@pauline836]

Glad to see this vid. Light teaching yet fraught of info and detailed process helps me go through my self studying for my practical exam.

[@gigilo0910]

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

[@burninhelenprd]

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!

[@abeeralfalahi8540]

I was really scared when we studied abt the cardiac cycle , but am not anymore.. it was really easy .. Thankyou so much sir .

[@jyothsnab.k3928]

Very beautifully explained. Thank you for sharing.

[@InteractiveBiology]

@jadsal92 You're welcome! Please stay tuned for more Biology videos to be uploaded very soon!

[@zorro5210]

totally awesome and your voice is so smooth and easy to listen too, no jumping around , concise all the way through. WOW!!! is right , so glad I saw this and your other videos. Give yourself a you tube nobel prize.

[@nabilbarsoom7935]

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

[@michaelgernatt5621]

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

[@kimberly2216]

This explains so much! Exactly what’s covered on my physiology exam thank you!

[@donnagarrison7847]

I love love love this teacher and entire description! Thank you for explaining it all at a glance!

[@Missprak]

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

[@rexexdesign]

Best video on cardiac cycle, hands down!

[@InteractiveBiology]

@CKB06 You are very much welcome! Stay tuned for many more :)

[@TijuannaBottleRocket]

Thank you very much. I hope you take pride in helping people!

[@InteractiveBiology]

@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.

[@laurenandre2732]

Whoa. Admittedly, I was so confused after just reading my textbook. This really helped me a lot, I enjoyed the way you explain things. Thank you 🙏🏻

[@Susunsusi]

Bio final in two days...u r a life saver!!can't thank you enough!:) :)

[@katedrake1171]

This is the best description I have found so far, you did a very good job explaining this! Thank you so much.

[@annetteasbury7415]

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!

[@dorsamavedatnia3417]

This video saved my life. Thank you sooooooo much

[@Nanomachines5on]

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

[@anti_fascist]

This is amazing! Thanks a lot! You're the best teacher ever.

[@teodorasecara4464]

Thank you for such a great explanation, you taught me better than my biology teacher !

[@MentosGumie]

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]

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.

[@megans7673]

Thank you for making this video! Made the diagram a lot more approachable when broken down into more simple parts. Much appreciated!

[@caohtrang]

I just got a decent grade in my last anaotmy exam! Thanks soo much to this channel !!! I have another exam comming up and this vid is awsome!

[@SirLadyChrome]

I usually don't like videos longer than a few minutes, but this is such a good video! It definitely beat the lecture (and was way shorter) :)

[@mominashaukat6566]

Thank you so much... I have my cardiology viva tomorrow.... It helped alot 🙌🏻

[@snowbear12159]

thank you so much for posting a video on the cardiac cycle, the graph is way less confusing!

[@ahmedbass1257]

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 ❤️

[@mariakiser]

makes it crystal clear...you should be teaching at my college!

[@gautamidusane5025]

Heyy !! I'm a student from India Thankss a lotttt ✌ Wonderfully explained It has helped me a lotttt

[@ahmedmansour9958]

its really a beneficial channels ever .... my appreciation for you .... i really was confused but after watching this video I really understood well

[@namkien9842]

You're such an amazing teacher. Your lecture is truly clear and understandable. But I hope you would add in the subtitle or description to help foreign learners could understand better :D. Thanks a lot!!!

[@emad8590]

I never thought I will understand cardiac cycle, thank you very much ^_^

[@Lunagirl50]

I owe you my life Leslie.

[@ToRnAdO0504563168]

you really made it fun not like our prof. in collage, keep up the nice work

[@MMM2345DDD]

I just discovered your channel. Great presentation with easy to absorb descriptions and instructional materials. I shall explore your other videos. Thank You!

[@InteractiveBiology]

@NYESTRELLA Glad to know it's helping. All the best!

[@sostoked07]

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!! :)

[@sarah5578]

Very well explained. Simple and to the point! Cheers!

[@ErikaJLopez]

I love your videos Leslie Samuels, you have a wonderful voice and way of speaking that keeps me intrigued!!!!

[@hannahburgol1563]

I've been having a hard time understanding the cardiac cycle and this helped a lot. Thank you!

[@TheDrT321]

Thanks so much. I go to one of the best schools in UK but I understood better with this vid.
