🫀 My other cardiovascular system videos:

_____
In this video, I describe the three types of cardiac tissue, explain the cardiac conduction system piece by piece, then map out what is happening in the heart during each stage of an electrocardiogram. The video covers these structures: sinoatrial (SA) node, internodal pathway, interatrial pathway, atrioventricular (AV) node, atrioventricular bundle (bundle of His), bundle branches, Purkinje fibers, P wave, PR interval, QRS complex, ST interval, T wave, ventricular contraction, atrial contraction, and heart sounds.

JUST SIMPLE, PERFECT, KNOWLEDGE RICH EXPLANATION, HUGE THANKS SIR 👍🏻👍🏻👍🏻👍🏻

[Otherlense]

The teacher that actually set his students for success. Thank you! 🙏🏽

[gdaymates]

FYI for any students on here. The sound is from blood hitting the valves/turbulent flow, not from the valves actually shutting.

[wasilwaesther]

Thank you Sir, I needed this before my semester exams which is soon🙏🏿. I love your explanations across all topics you discuss, yesterday I was able to grasp one of them and here today am grasping ECG and Heart Conducting system

[malikfasih]

Great explanation. Especially for people from non medical backgrounds.

[marisolMorales-gjcq]

You are such an amazing teacher, finally I got it

[onogoep]

This is so helpful !!! You're a life saver !

[dulcevargas]

I wish my professors could teach like this.

[mediatrixchekwube]

you are more than a textbook! after watching your videos it sticks with me, you made my exam or quiz so so easy!
thank you so much for your wonderful amazing videos!!!!

[ninmamu]

Thank god you and your videos exist 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻 thank you for sharing.

[SongOfSongsOneTwelve]

Can you please 🙏do a series that will help us master reading ECGs?

[josephb]

I love watching your videos !! Please keep making more heart rhythms like STEMI locations, arterial blood gases

[RedemptorGichana]

Thank u sir, I didn't know it's simple

[PariyaRajabzade-ntnt]

The best biology teacher I've ever seen 😍 👌 🙌 💖

[hamadeliterank]

You are AMAZING!!! Look I'm all the way over in the Middle east and you're helping me. Thank you man so much!

[zoltangaal]

Good video. It's important to emphasise that ACG doesn't show muscle contraction or pressure change in the chambers at all.

[omerbozdemir]

Please make a detailed video about muscles asap 🙏🏻

[ElizabethOdero-srdu]

kindly would u make a video of the process of photosynthesis 🥺 pls

[morgancalvi]

You said all blood is red, never blue. So are the blue things we see in out arm and hand un-oxygenated blood in veins? Also is the noon-conductive fibrous tissue only in a band...or is it through out the entire heart?

[SongOfSongsOneTwelve]

By the way, have you ever heard of piezoelectricity! I believe that when the fetal nervous system is formed, that is what starts the SA node. What do you think? That is my personal theory. Thanks for your knowledge! ❤
