Understanding the Normal ECG Thoracic Key

Web1 de jan. de 2006 · The approximate location of the mean electrical axis can be found by identifying the lead with the tallest R wave. The mean electrical axis will be within 30 degrees of the positive pole of this lead. In this ECG, lead II has the tallest R wave, indicating that the mean electrical axis is normal. 4. WebIts positive monitoring electrode is located on the right arm and looks downward and to the left. The mean vector also flows downward and to the left, directly away from lead aVR, resulting in a negative deflection for all waveforms. In a normal ECG, lead aVR is the only limb lead with a downwardly deflected QRS.

WebVerified by Toppr. Correct option is C) In the normal ECG, the QS wave shows the negative deflection. In the QRS complex, the first negative deflection is shown by the Q wave which is followed by the positive deflection of R wave. Again, the R wave is followed by the negative deflection of S wave. Therefore, the correct option is C. WebNational Center for Biotechnology Information
