This is the simplest and clearest vid I've come across. Obviously haven't seen every vid there is available, but this sets the standard IMO. Well done

[@ashwinkola71]

Thank you so much! The part in the end that highlights the corresponding heart sound was extremely helpful!

[@Bang0518]

im a visual learner and the graphic paired with the sound helped me a lot in differentiating a seemingly the same sound. thank you so much.

[@doctorshocker619]

you're a life saver, lucky to have found this channel !!!

You guys just solved my problems in a beat. How can I like this multiple times❣

[@smilestormb.5260]

Awesome Mehn!!!. Never really appreciated these sounds. Now it’s makes so much sense. Esp the S3 and S4 distinction

[@prateekmisra8251]

S3:
- Thought to be caused by the oscillation of blood back and forth between the walls of the ventricles initiated by the inflow of blood from the atria.
- May be normal in people under 40 years of age and some trained athletes but should disappear before middle age. Re-emergence of this sound late in life is abnormal and may indicate serious problems like heart failure.
S4:
- While the mechanism is not absolutely certain, it is generally accepted that S4 is caused by stiffening of the walls of the ventricles (usually the left), which produces abnormally turbulent flow as the atria contract to force blood into the ventricle.
- S4 is sometimes audible in the elderly due to a more rigid ventricle. When loud, it is a sign of a pathological state, usually a failing left ventricle.

-4th year med student on rotations

[@neelneelushah0]

You don't have have to mention which fucking year you are.

[@SnowFlyGG]

In rotations and still not recognize pathological sounds in a heart? The pandemic ruined the students.

[@flaminmongrel6955]

@@SnowFlyGG was thinking the same I'm a physiotherapist student in first year and already knew it from my physiology class but came here for a better understanding.

[@caelum8900]

great video for learning to differentiate these confusing sounds

[@drrita5863]

Nice

[@aashir786ss]

Sounds kinda catchy tbh

[@saintsam7397]

ID 2108 on uworld doesnt sound like this to me, trying to memorize how they sound but I dont think im getting anywhere. after watching your videos I feel like a pro and then I try to do this question n im like whhhaaattttt?

[@omarhassan2751]

how to differentiate that from splitting of S2?

[@lylakassar7284]

Great

[@xiaoyueliu8328]

Great content! However, the volume of heart sound is very low, so I turned up the volume, then the bell sound at the start of your video almost made me deaf because its so loud and sharp. Consider make the volume of your video evenly through out.

[@m.bprajapati8921]

How to differentiate wide split S2 and S3?

[@mantree8047]

I heard it today in a patient of MI.

[@sd123456789100]

Actually I like the music♥️

[@amritbhele8635]

This video made it ao easy

[@theevilwithintheory.medica1494]

I didn't knew the heart can play drums

[@ekram-eq9xh]

S3 feels like your in disco … s4 is abit more serious

[@waadkhaled5335]

Hahahaha!

[@fatm4403]

😂😂😂😂

[@Annnonymous]

Scary theme like the beginning of horror movies 😁❤️

[@zarrnasy6184]

0:12 S3
0:17 S4

[@mirjamw6665]

kentucky is S3
LeLub Dub is S4,
Listen at the apex of the heart, with bell (cause it is a low frequency)

[@LordPinkiePie]

Am i the only one thinks its a good beat for making music ?

[@medzcool]

Nope, I think it’s perfect for making music! 😄

[@koryaiine7393]

S1234 kinda sound like In The Jungle The Mighty Jungle song haha

[@manojr611]

should play this in dj

[@itsomethingreat]

Cardiac auscultation is so subjective

[@LoversGrief]

So S4 splits S1? Is that it?

[@linabelhout3219]

i cant heart the difference between normal heart sound and s4 heart sound..... 😢

Rock me Amadeus.

[@Blue97Shark]

this is 5 stars
