@@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.

Thank you ma'am again....iam watching again after first year mbbs in final year 🎉

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

2 жыл бұрын

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

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?

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

@PhysiologyOpen

2 жыл бұрын

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

3 жыл бұрын

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 ...

@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).
