Just wow wow wow! I spend almost 1 and half day having 3 3 hours of lec on understanding this concept but i was having a lot of questions, then i came through this video! Made it easy for me!!!! Thankew

[@PhysiologyOpen]

Love it❤️. Keep learning, best wishes

I have seen a lot of videos on ecg ,leads during my struggle through understanding its basics...then i came across ur video...u are just so smooth and simple with the concept...i love your video mam.🥰😍

Thanks...Physiologyopen is all about concepts. Happy that the video helped.

Succinctly put and great job. I was missing some info on unipolar leads from other videos. You clarified it in a very nice way.

[@PhysiologyOpen]

Awesome, thank you!

[@texastexas4541]

@@PhysiologyOpen Hi! I am wondering if you could clarify one thing for me. When a cardiac vector is at 90 degrees to a lead axis, why is it equiphasic (equal amounts of positive and negative deflection) rather than zero? When is such a situation zero and when is it biphasic? Books confuse me in this regard. Thanks for your help in advance.

You might have seen Lead II ECG. Can you tell which ECG lead will record an ECG just opposite to that, i.e negative P wave and even negative T wave and Why? Watch the video and find out..

[@aminmodasiya9335]

AvR....??

[@PhysiologyOpen]

Correct...can you tell why?

[@aminmodasiya9335]

@@PhysiologyOpen Mam because the direction of lead 2 is in the direction of depolarization and the direction of lead avR is in the opposite direction....

At 10:58 is’t supposed the direction of chest lead come from the negative” the comination of three limb leadss” toward the chest electrode which is positve?

[@PhysiologyOpen]

Yes…the three limb electrodes when passed through high resistance become zero..and are at center of heart

[@abhinashsharma3456]

ma'am what I am not getting is , potential difference is a scalar quantity then why are we applying principles of vectors in ecg

[@PhysiologyOpen]

Yes currect. However body acts as a dipole with movement of charges, so current flow occurs. Now here we are describing as spread of depolarization, necause it is easy to understand. Classically in books, it is described as current flow. However, for explaining both ways are correct

[@saeedrkhan1372]

Mam in non exercising muscles blood flow is regulated by.: Sympathetic adrenergic?? Right.. Or cholenergic...

[@mohitahirwar8183]

Mam I'm confused in the ventricular repolarization vector direction please explain

[@PhysiologyOpen]

In ventricles the area which gets depolarized last (epicardium) gets repolarized first (so it will come to RMP, while other areas are depolarized)..now yoy draw vector from -ve to positive..it will be similar to that of the major vector of depolarization..from right to left, up to down...it will be recorded as positive wave in lead II

Limb leads used with chest leads are called non augmented unipolar limb leads ?

[@PhysiologyOpen]

I didnt get your question very well. But chest leads are unipolar leads . for that we require one end of the lead to be at zero potential. The potential from all electrodes on limbs is added up and passed through high resistance so that it becomes zero. (all this happens automatically in the machine). If this is the answer you are looking for ...

[@rohanrajput8255]

@@PhysiologyOpen Limb lead jo chest lead ke saath use krte hai uska koi specific name hai ? Or 12 leads mai inhe count kyu nhi krte?

[@rohanrajput8255]

Mam, why you are not replying?

[@PhysiologyOpen]

Sorry for the delay in replying, had been busy. No there is no specific name as much as I know. We do count them in 12 lead ECG. Basically, we are keeping electrodes on limbs. when the machine records potential difference between limb electrodes we call them as limb lead (lead is a combination of 2 electrodes) Now when the machine passes the output of same electrodes kept on limb to high resistance, the potential becomes zero. So this is used as negative electrode for chest leads (for whom positive electrode is kept on the chest).
