Figure 2: System of limb lead ECG. lead eld idea in that there is the lead vector for each of the three limb leads, I, II, and III, that correspond to the sides of the Einthoven triangle. In this lab, you will record the standard limb leads in sequence, according to the diagram in Figure 2. Before calculating the heart axis, we must understand that each lead represents a different point of view of the same electrical stimulus.. To calculate the cardiac axis we will only use the limbs leads. Taking the example of the bus, the Limbs Leads are 6 windows that look to the heart in the frontal plane, that is: from above, below, left and right.. Never from the front or back si electrical axis of the ventricle . Ventricular Depolarization . Lead Placement • Limb leads 10 cm from heart • Precordial leads placed exact ... • With vector manipulation ECG machine creates aVR, aVL, & aVF . Hexaxial System • Used to determine electrical axis • What is the normal axis for the heart? • -3...
