You haven't told about the na+ channels which operate during end of phase 2 whilst explaining the graph but you mentioned them during the action of class 1b. So what do these na+ channels at the end of phase 2 do ..Influx or eflux..I'm confused

Phase 4 of SA node depolarization is by If (funny current) which is a combination of Na/K ions as sodium channels are disabled in SA node

13:49 Na channels in late phase 2?! That can't be right. Can anyone please tell me how Ib drugs shorten repolarisation?
RockyCycle (4 месяца назад)
Your videos are usually top notch but I find that this one isn't as detailed as it could've been. I'm actually more confused after watching this video than I was coming in, and that's saying something.

Er pp (11 месяцев назад)
Thank you so much for these videos!!! I just have a quick question regarding Class 1b.. you refer to some Na+ Channels that open in late phase 2 but I didn't understand which channels you are referring to because I only know of the ones at the very beginning.. are there other types too or is it these ones? I would really really appreciate if you or anyone else could help me!
RockyCycle (4 месяца назад)
SAME! I'm pretty sure it's a mistake. I've searched though all my textbooks, and all over the internet and nowhere did I find anything remotely close to what he's saying here.

3KBS Channel (1 год назад)
Great video. But I think there's a mistake regarding Class Ib drugs in the mechanism of action
RockyCycle (4 месяца назад)
I think the mistake is where he says the class Ib drugs shorten repolarisation by blocking *Na channels* that activate during late phase 2. Doesn't he mean K channels? or am I mistaken?
LR Bolotin (5 месяцев назад)
That's what he said, they block Na channels. However, they have the weakest blockage compared to IA and IC
3KBS Channel (1 год назад)
As I think they mainly block Na and not as you mentioned, sir.
