Web1. At. , Mahesh stated that if the electrons is moving downwards, electric current will be moving upwards towards as electric current moves towards the positive charge. I would like to clarify my understanding on this - we learnt in circuits that electrons move in an opposite direction from the conventional current (which moves from positive to ... WebThe interpretation of the electrical heart axis has a few rules of thumb: First, when a positive depolarization wave moves towards a positive electrode, a positive, upwards deflection is registered on the ECG. Second, there are 4 quadrants where the QRS-vector can point to: left upper quadrant --> left axis deviation (between -30º and -90º)
