Hi doctor Rajeev, I am 4th medical student, I would like to ask you regarding for Right bundle branch block (RBBB)- what Precordial leads should appear rSR waves: only V2 or both V1 and V2 ?
I am a student pharmacist and having this as an extra resource to vary my study strategy always helps a lot to do better on exams. Thank you so much and keep up the great work!
This video is everything!! I understood the classes much easier than I did in my pharmacology class. It could be the way he separated the slides. But your visuals on the stages helped a lot, I'm such a visual person. Thank you
I am short of words to express how greatful I am for your videos.The way you explain difficult concepts in a very simple way is unbelievable.Thank you so much.
I have watched countless videos on the hearts electrical conductivity which still left me confused in certain areas but this makes it and more crystal clear! Thank you very much for posting, much appreciated.
Thank you sooo sooo much. i am a type of guy who hate to read books and love to listen. You are a perfect teacher for everyone your lecture is crystal clear pls do more videos related pharm D
lot of thanks and lot of love from pakistan......border confilicts and other tensions can not impede us to be proud of people like you.....may u live long and blessed.......
Superb video tysm ........ I have my exam tmr & u saved my precious precious time from reading old books by including the basics in the video. Tysm again. Just don't ever ever delete such good videos
that brief explanation of the ECG helped me understand the differences and descriptions of each wave. It shows how excellent of a teacher you are. Please keep it up. Thank you for helping us.
You have explained anti-arrythmics better than any professor in medicine school and than any other tutor in YT. Thank you, I finally understand Anti-Arrythmics
I think in 6:10 , it's the leaky Na and Ca channels which cause the phase 4, then it's voltage gated ca channels, which cause more ca2+ to influx, resulting phase 0, rest is correct! There are two different ca channels!
Thank you so much for explaining the pacemaker potential and cardiac muscle cell potential, I learnt that in my lecture but I just fully understand it after watching your video 😊
It's very conceptual and very clear. Thanks a lot and expecting more videos. Please upload videos on antianginal drugs, anti ischaemic drugs, and drugs for heart failure.
I really have one doubt, in the cardiac muscles cell , K ion will remain inside the cardiac cell at resting phase[ 4] -90mv , but at the time of repolarisation it will start going out of the cell
In Resting phase cell has greater K concentration inside . In depolarization Na influx increase membrane potential in + values , so action potential occurs In repolarization , K leaks / pumped ouside the cell , this decrease the membrane potential and its value becomes negative ,thus action potential is terminated
thank you for this video. I'm a practicing LPN. Loved the physiology before explaining the mechanism of action. Some of this I have to replay to get it, but it breaks it down. I need to go over more deeply the Action Potential again.
Helloo speed pharma , i have one word for u.u r and all ur videos covering pharma world is just awesome.i wish u can teach some pharmaceutics and statistics of pharmacy too.thank a million .
13:58: Class Ib drugs shorten the AP via blocking phase 2 Na+-channels? But there aren't any Na+-channels active in phase 2, at least not mentioned in the vid.

thank you perfect video can someone answer this : slowing down the influx of sodium ions into cardiac muscle cells causing a decrease in the excitability of the cells it has a beta adrenergic blocker which can cause bradycardia and bronchospasm : sotalol propafenone verapamil mexitilene
At 13:50 how does the blockage of Na+-Channels shorten repolarization? If the Na+ channels are reactivating in late Phase 2 they still aren't letting positive charge into the cell since they're refractory right? I'm a bit confused as to what the Na+ channels have to do with repolarization, so if someone could clarify, it would be much appreciated :)

@@archikogan agreed, the worst are UK GPs who seemingly only listen to their local authority's formulary and disregard all scientific evidence
Very helpful

Thank you so much.
Thank you!
Love
You just saved six minutes and six seconds of my life!
Not only are these videos incredibly helpful, easy to understand, and invaluable to me, but I just love this guy's accent!! So soothing!
I'm really glad you went over the physiology before discussing the antirrhythmic drugs, this is a perfect video for any student of medicine!

Still relevant today :) I make and revise my concept maps and up to this day I review them before sleep at most days and I still didnt forget them!
This video is amazing, this dude is epic explaining. Better than any med school for sure.

Thank you for saving me from a mental breakdown 😂
This was wonderful 💯. I'm a medical doctor and this really enlightened my understanding. Kudos 🎉👏
Your videos are short, precise and useful. Thank you and please keep making them.
Thanks
Came for pharmacology, learnt also about ECG. Thank you!
Thank you so much for explaining the pacemaker potential and cardiac muscle cell potential, I learnt that in my lecture but I just fully understand it after watching your video 😊
Yup
I'm a practising cardiologist from the past 69 years. I still learnt from your video. Congratulations.

One of the best channel for pharmacology
In med school. You teach me better than my professors.
That was an awesome video to watch before my exam! Thank you!!
I appreciate the way u teach is superb sir 👏👌🙌

Mr rajeev god bless you. Thank you soooo much . I understand everything about this topic . 🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤😇😇😇
It's really helpful and the way you explained it so amazing it's add more to my knowledge thank you!
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
There are no fast sodium channels in nodal tissue (SA and AV node). Phase 4 and 0 in nodal tissue are due entirely to Calcium influx
What you said is correct about Phase 0, but is not true about Phase 4. Phase 4 is due to influx of sodium by the HCN channels (Funny sodium channels)
Best explanation and best content. Even paid workshop don't give such organized information. Thanks a lot for your efforts ..❤❤❤
Helloo speed pharma , i have one word for u.u r and all ur videos covering pharma world is just awesome.i wish u can teach some pharmaceutics and statistics of pharmacy too.thank a million .
Great lecture. Cleared all my concepts. Thank you.😁
Beautiful explanation for a very complex area in pharmacology
Note: The Vaughan Williams Classification was updated 2018, so now there are 7 (8) classes of drugs and multiple subclasses.

This video was very good .thanks for you🥰
Thank you very much for posting this lecture it definitely was well done and I will be following your other lectures. Thank you
Class 1B shorten APD and relatively prolong the ERP
what is APD and ERP???
thank you perfect video can someone answer this :
slowing down the influx of sodium ions into cardiac muscle cells causing a decrease in the excitability of the cells it has a beta adrenergic blocker which can cause bradycardia and bronchospasm :
sotalol
propafenone
verapamil
mexitilene
