Conduction System of the Heart 

Thank you so much, Susanna! You have no idea how helpful this video was.

You have NO idea how much this has helped clear up a really bad lecture. Thank you.

Your videos are lifesavers. THANK YOU!

Subscribed! I’ve been watching a bunch of these to prepare for the HESI I never realized how much of a visual learner I am until I started studying your video over the past 5 days

These videos are amazing. Thank you for sharing them.

Extremely well explained and covered the most important aspects!

Here is the link to some of my notes: drive.google.com/open?id=0B1opKPCEPfC_YjlrZ01qYkNLMlU The conduction system notes are pages 168174-. Enjoy!

Very nicely explained! Great voice, great handwriting and great graphics!

u explained everything so clearly with no gaps. my millionth video

Excellent, I have no words to appreciate your way of explaining the conduction system of heart I wish you success in your mission thanks 10,/12/2019

You are really good explaining! Thanks for the video!

You are a savior! Thank you so much for this! And all your videos are so great!

Thank you soooo much, I understand know I was lost in class. Great video you explain everything great and slow. :)

I've been looking for this. Thank you so much 😘

super video lecture , my all confusion are clear. thank you so much

Very helpful! Thank you!

your video helps me to understand conduction system easily . thank you so much . sushanta.

So explanatory..... thank you so much

thanks for your competent explanation, how helpful!!!

Great explanation!! Thanks so much :)

thanks. Made it nice and clear for me. Radiography exams soon so some Cardiovascular revision was called for :)

very very helpful! in very plain language!

Thanku so much ma'am, I m a first year Mbbs student, and this is very Helpful

Well explained, thank you so much 😊

thank you for the great effort

I understood it all just because of u ! Thank u very much!

Thanks to you.. Your video is helping me alot

Do you know why parasympathetic action potentials rarely reach my heart? Because what happens in vagus, stays in vagus. Have a good day

Great video!!!

I give thanks anlot to Susanne,may God give you rewards.Amen

Thank you so much, you’re so smart.

Well explained.thank you

You are saving life 💖💖💖

excellent!!! thank you!!

nice video love the heart

thank you very much your pronunciation is very nice

Hi, I've read that athletes have a slower resting heart rate, maybe 45-50bpm. So is possible to "train" the SA node to beat slower with regular exercise?

I want to say thank you if you still there make more videos plz 🙏

This was a fantastic video!! Thanks for making it :) Still trying to wrap my head around the T wave wave.. Why is the "bump" positive, and not negative, if this is a repolarization event?

@susannaheinze I am struggling with understanding this, I am aware that when the heart is re polarizing by K+ GOING INSIDE THE CELL which makes it become negative, but in your video you are saying that when K+ GOING OUT OF THE CELL becomes more negative after repolarizing that leads to hyperpolarization. So how is it that when K+ leaves it becomes more negative? Since we know that K+ coming inside the cell is what brings down the threshold to a more negative state. Please can you explain, I am so confused.

Brilliant she knows her stuff x

I think you find your calling. Nice work! Because of my recent (2016) AFIB diagnosis and two catheter ablations, I am studying the heart to have a better conversation with my EP[Electrophysiologists]. He's going to love my youtube knowledge or maybe not.

Best explained thnQ mam 💝💗

Thank you.

Thank you I appreciate you very much

one word im grateful

Thank you so much 🙏🤗🌹

Thanks I was lost for a minute.

Amazing dear 😘

You are a blessing

Vry vry intrsting lec excelnt😃😃

Excellent

Do you have these for down load or printing?

life saver thanks

thank you.....................esp.for that bit physiology part

Very nice drawing and explanation, but WPW (Wolff-Parkinson-White) syndrome is not 'autorythmic atria', it is an antegradely (and often also retrogradely) conducting accessory pathway bypassing the normal AV-conduction via the AV-node, leading to preexitation of the ventricle its connected to. In other words, it's an extra connection between the atria and the ventricle next to the AV-node. This pathway is responsible for orthodromic circusmovement tachycardias and if conduction over this pathway is so called malignant (very fast) it can lead to ventricle fibrillation if the patient has atrial fibrillation. Other than that, a very informative presentation.

Does AV Valve open in disstole phase? Thanks 🙏

Watching in lockdown ❤️💞💕💞💕

In sympathetic nerve supply to SA node I think it might be T1 to T4

thank you so much, you are amazing

Thanks.

awesome

so helpful, a video

wooow !! so damn useful !!! thankyou so much ♥

AMAZINGGGGGG!!!!!

perfect explanation..

Thank you~ ^_^

Thank you

How does the SA node generate the initial impulse?

Thñku mam 😊

nice

👏

tq nice

Hi and thank you for the lecture but can you please give me a copy of your notes. i like the way i am able to understand things that i cant get in my lecture class.
