Frank-Starlings Law Explained - EMTprep.com

[@kevinpolpitiya3200]

Hey look at that. In less than 3 minutes, I understood what our lecturer failed to explain in 30 minutes. You sir, are a lifesaver

[@Emtprep]

Happy to help Kevin!

[@さくら-i5i9z]

it is a simple concept, but this video fails to actually explain it properly. i suggest you look for other more in depth videos. Frank Starling Law also explains why there is reduced cardiac output in cardiac failure, a concept of which this video didnt explain at all

[@umadhanesh172]

Bro u first listen to the class with 100% conscious . Poor boy

[@echanelle05]

also the way that you explain end diastolic volume as the volume after relaxation right before contraction helps so much and Im going to remember it forever now. I was able to apply the same thing to end systolic volume

[@echanelle05]

wow, i wished i found this video before the exam. I'm reviewing the concepts I missed. I'm not sure why professors like to take the simplest of concepts and make it more complicated than they really are. I think it took my professor 30 mins to explain this. He provided us with lecture notes on the topic, but that was a page and a half and it had many complicated vocabularies. So thanks! You explain this so well. even the definitions of pre-load, EDV, etc that I was struggling with.

Can I ask what all was on your exam that you can remember?

[@fatima3590]

3 foundational terms End diastolic volume 0:29 Pre load 0:55 Stroke volume 1:33 Frank starling mechanism 1:55

This has to be the most simplest way to understand this, thank you!

[@jjjakumbbs1043]

That was a quick, easy explanation of it so thank you very much😅✨

[@Sa-bm4ri]

Explained this so well. Thank you!

[@makeye]

Why isn't EDV the same as preload?

[@rachelsun5400]

great video. Thank you!

[@Chibbit1000]

Described so well! Thank you !

[@user-sq3ls6sj7i]

Does stronger contraction mean higher blood pressure?

[@elanalottner7542]

why would a greater stroke volume necessarily cause or indicate a more forceful contraction?

[@Emtprep]

Great question Elana, think of it like a rubber band, up until a certain point, the more you stretch it out the greater the retraction is.

[@chafikjaaouan7347]

Because the actine-myosine filaments will be stretched too, and when you stretch it, it will contract faster and harder (till a certain point). and rubber band example of EMTprep is a good one

[@hyper_quick5248]

Hey guys I’m in an emt program right now and I’m doing good on all my tests on our book, but continue to struggle with scenarios that our instructor gives me. Any suggestions?

[@Emtprep]

Hey Hyper_Quick, memorize the NREMT skill sheets to start. That way you're doing the scenarios in a similar manner to how you'll be tested. Besides that, consider purchasing EMS scenario books and reading through them. That could help you get more familiar and more comfortable with them. Hope that helps!

[@FEFI2U]

Ask yourself are you a good basic? Answer is yes! Then handle your calls as such and when you need Pmedic meds you know which ones just add that in it takes a good basic to make a great Pmedic... believe in yourself confidently take the scenario as you already know the book and materials there are some you tube videos with scenarios. Good luck! Take a deep breath and own it!

Really great video

you made it so easy, thank you

Thank you this was very helpful.

[@anfelgh1755]

This is a really good video

[@seera7662]

Very helpful ‼️💙 thanks 🙏🏻

[@maxhuber1361]

Thanks for the video, I think the order of the last two points should be reversed -> more forceful contraction = more sv:)

[@stevenreyes2398]

Same thoughts mate

[@nssq8870]

I respectfully disagree The more per load there is the more sv that would eventually get pumped which also means the work the heart has to do (more forceful contraction) is larger

[@MACKSview]

@@nssq8870 I respectfully disagree. The heart needs to contract first before it ejects blood (SV). So, it would make more sense if it was More edv > more preload > more forceful contraction > more sv !!!!

[@kelvinbuljubasic6957]

Helpful, thank you so much!

[@dilkibat823]

Omg it is so easy 😘 thanks for concept

[@aathorpo]

but does it equal faster heart rate, same or slower?

[@Emtprep]

Hey Aaron, it doesn’t equal any of those things. The law discusses stretch of the myocytes based on stroke volume of the left ventricle.

[@kritisharma6239]

Nice explanation thank you 😊

[@kisshorekumar4331]

I'm pretty sure that 62 is roll number right? Same 1st year here😂😂

dev fills the blood before contraction you said after

The more forceful contraction is only true on a healthy heart.
