MUST WATCH: Affects of Hyperkalemia on cardiac conduction

[@bestreactionvideos2044]

Finally, someone that clearly explains this! I was very confused about the seeming contradiction of easier depolarization = less efficient heart rate in hyperkalemia. But this makes sense now!

[@Sk1pperCS]

Beautifully explained. Thanks so much.

Calcium has a 2+ charge. So if 2 k go out and 1 ca2+ comes in it's still balanced, or am I missing something?

[@elakiyamohan9821]

Thanks for clearing my long time confusion ✨

[@acepance5592]

You are very welcome!

[@socialcovalency1717]

Very nice explanation sir, my concept is now clear due to this beautiful lecture thanks 🙏

[@thisisbryce6358]

Thank you so much for creating this well explained video!

[@acepance5592]

Glad it was helpful!

[@sumaihz8375]

thats awesome , so to recap , hyperkalemia may lead to heart stop contracting ? and hypokalemia may lead to overactive heart ? am i right ?

[@acepance5592]

Yes hypokalemia makes patients more prone to arrhythmias esp if they have underlying heart issues to begin with. These patients can develop v-fib, torsades

perfect !!

[@erikalittle418]

Thank you so much for explaining this! I just never understood why in the plateau phase if there is a one to one trade off of calcium and potassium how is the electrical Potential difference kept the same if calcium has a charge of +2 and k is +1 . Does that not factor in?

GREAT

[@nikkirosety]

So useful! Thank you so much.

[@amaniwilliam747]

Thank you sir. I have a question about early repolarization, how could it happen while I have a lot of K out, shouldn't it stop coming out because of high K out?

[@acepance5592]

Well the late rectifier channels open earlier because of the high potassium outside. Normally the ions move from high concentration to low. Thats passive influx and outflow however, with channels we can use ATP to force ions against its gradient. In this case, thats exactly what's happening. These channels get activated and depolarization starts early. Does that make sense?

[@amaniwilliam747]

@@acepance5592 yes, I got it. Thank you so much.

[@AtikaHafeezIqra]

Yes please tell how

[@mahbubamaria1742]

Can You make a video on the mechanism of changes in ECG due to hyperkalemia and hypokalemia soon.Because my exam is knocking at the door. I have searched a lot but couldn't find any satisfactory video.

[@acepance5592]

I will try my best but it maybe difficult given the time constraint.

[@azmaalifia9445]

Sir loved it.... But I have an doubt how in hyperkalemia state diastolic arrest took place ?

[@acepance5592]

Hyperkalemia slows down the cardiac conduction resulting in V-Fib or asystole leading to cardiac arrest. I will create a separate video on diff electrolyte abnormalities and arrhythmias associated with them

One k going outward and one calcium going inward is not the same calcium charge is 2 and k is 1
