@@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.

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

@PhysiologyOpen2 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 ?
@PhysiologyOpen3 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 ...

Mam, why you are not replying?
@PhysiologyOpen3 жыл бұрын
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).
