Excellent explanation! Thanks a lot this really helps!

Only video on youtube that clearly explains this concept and not just "calcium changes the threshold potential" Thank you!

Brilliant!!

Good job sir, thanks

here is a summary that i found for those who didnt understand how ca+ rises the treashold : Threshold potential: largely determined by the voltage gated Na channel. In short, when membrane potential reaches the threshould, many voltage gated Na+ channels open and lead to Na+ influx and subsequent action potentials. Ca2+ ion alters the property of these voltage gated Na+ channels and make their "gating voltage" higher, aka less negative. By doing so, these Na+ channels open only at a higher voltage. Thus the threshold is raised and the difference between the resting potential and the threshold is increased. In other words, cell become less excitable.

thanks the only video on yt that explains this concept

But sir you have made mentioned of increased in fluid reabsorption from the kidney in CVS changes but at The renal changes you said it increases GFR which lead to increased in urination.

"The impact of hyperkalemia on the rectifier potassium channels " cleared my doubt ❤

Great class! I was looking for a class like this since a while, thanks a lot

thanks for making this video, this is an excellent presentation.

Thank you for the video, very helpful! Can you give some examples of what could cause a unidirectional block in the fast pathway?

this is so amazing ! thank you professor

Thanks, this coupled with this video ruclips.net/video/vSrW4jg8Zq8/видео.html Helped me understand both ST depression and T wave inversion completely, for these videos complement each other. Thank you for a clear explanation

I'm bradycardia without symptoms my resting heart rate is the low fifty's to the high forty's my doctor says I'm doing fine

Great explanation, thank you so much ❤

Thank you! Very clear concept

You are just amazing ❤ thank you

Thank you. Your videos are very helpful

Sir, your videos are brilliant!!! The way you explain concepts makes it crystal clear.. Please please upload more videos on STEP 1 USMLE content. Thank you

Is this c section or nsd?

Thank you very much sir🫡🫡

Could you cover more ecg’s and videos regarding that? Thank you!

Great video! Love reviewing these topics you make.

What books do u use?

hey Dale thanks for the video It seems you are starting to make video again, I encourage you to keep going. your videos are actually really helpful. more power to you man 💪🥳

could you explain how calcium gluconate increases the threshold potential....I found this part of the video very confusing because you said calcium gluconate increases the membrane potential above the RMP? Then you said calcium gluconate increases the RMP?? Then back to calcium gluconate increases the threshold potential. All around the 7 to 7:30 mark.

You just did it less than30 minutes and it's clear thank you so much🎉🎉❤

Thank you for explaining this. Learning Reperfusion beats in Nursing School and I appreciate how you described it.

Thank you so much Dale! This is exactly the way I learn best. This video has saved me

This is such a well-detailed explanation. Thank you so much!

This video is incredible. You summed up multiple medical school topics in this description. Thank you!

Your explanation of the respiratory system is truly awesome. None of the other videos on youtube come close to how well you teach. Hats off!😊

Hello sir Isn't PR-interval implies current in AV node?

the best explanation; thank you sir !!

Super detailed!

Hello Dale, thank you for your very informative and well illustrative video. I learned a lot. Was wondering if you might look at an EKG of mine. I have a 1 mm negative post positive T wave, it is very brief following a quick return to baseline. It is on lead 1 from a at home ekg/ecg monitor. So only 1 lead (a wearable). Wondering if you might be willing to take a look at it and tell me if you think it is normal, artifact, or early signs of ischemia? Thanks T

Amazing! Thanks so much for this

By far the best video on AVNRT. Thank you

Very helpful video. Thankyou

Thank you ❤

Hyperthermia and hyperpyrexia ? Are these both same ? If no whats difference ? Why are these mechanisms happening ? Thankyou. ( thankyou for great service )

Thanks a lot

I have been struggling with this for a while and this is the best explanation I've come across, thank you so much!

Isn’t it that lidocaine blocks the sodium channels in Inactivated state , which means depolarisation has already occurred , so there might be just a small deflection rather than such an appreciable change in slope ??

Best video EVER!!!

Great video I just have one question. Could you explain why the speed of repolarisation i.e epicardial tissue repolarising before the subepicardial tissue dictates the net flow? Thanks

I recently had an experience with heat exhaustion and somehow stumbled upon your video - I've had a lot of teachers/mentors in my life and you are an amazing teacher - wow!
