    Infact I was given as an assignment by my physiology teacher to look on the electrocardiogram,, but since the top most genious lecturer has elaborated it in this simple way,,,my fellows I promise I will present this to my teacher!!!

    Your videos are literally a life-saver for school. I'll read a concept, not understand it, and then watch your videos to really GET something. I don't have to memorize nearly as much now because your videos help me actually understand the concepts. THANK YOU!!

    You are a genius; you are so good at what you do. You do not assume knowledge. You present all your topics in extremely clear and logical manner. I have learned a lot from you and I would like to say a BIG Thank you to you. Please do not stop making videos. You are making a big impact in many lives. God bless you mightily.

    Better late than never, had a vague concept of how heart works, your video living up to Ak lectures motto, hepled me in grasping the CVS topic in short time, without any financial cost or loss of energy. Thanks fr saving from the academic redtapism .

    Perfect lecture and explanation, I only have one correction :The atrioventricular valves are actually open before the atria start contracting,and 80 % of the blood flows passively through pressure differences in the ventricles.they only start contracting in the end so that they can „squeeze“ the rest 20% of the blood into the ventricles. Thanks for uploading greetings

    Aren't the two AV valves already open, and the ventricles fill 70% by passive means then the atrial sístole pumps the remainder. Just thought I would throw that in there

    Why is P and QRS a depolarisation while T and U are repolarisation waves although all produce a positive deflection.

    • @Man_Aashiqe_sarmastam
      @Man_Aashiqe_sarmastam 4 года назад

      p and QRS are positive cause increase in voltage takes place during depolarization of atria and ventricles but T-wave is positive as well because "the last cells to depolarize in the ventricles are the first to repolarize."

    Oh I didn't know that you cover lots of subjects. Your videos had made me improve a lot, thank you.

  • @jkawalsky11
    @jkawalsky11 7 лет назад +3

    I don't understand. I normally associate depolarization with an increase of voltage. But here there are points when it repolorizes but the voltage increases. For instance the T and U waves. Why does the voltage increase for repolorization?

    • @rosa33942
      @rosa33942 7 лет назад

      the T is in repolarization representing the ventricles after contraction,,,compared to the QRS ...they have a charge but its reduced.....I think!! lol

    • @BrolicG
      @BrolicG 7 лет назад +3

      I don't think depolarization is an increase in voltage, rather, I think it is a decrease in voltage. voltage is the potential difference between two charged 'things'. so when a cell membrane depolarizes, it approaches 0 mV (no potential difference), so voltage is decreasing, not increasing. except when it hyperpolarizes, it not only approaches 0 mV but goes beyond to the positive side, still increasing the potential difference after it had decreased (gotten to 0 mV).
      i hope i made sense.

  • @dante911ify
    @dante911ify 4 года назад

    Why does repolarization of the ventricles(which is basically the decrease in membrane potential) causes an upward(positive) T wave ? Shouldn't it produce a downwardly(more negative) wave ?

    Guys can anyone explain to me what is happening in the heart strictly between the blue R and the green Q segment. Is that atrial repolarization? Or is it something that needs to happen in order to see ventricular depolarization? Or both? Lol...this question is killing me plz help!
