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. Web“In an ECG showing normal sinus rhythm, ... Positive in lead I and negative in lead II. 6. When naming the waveforms that make up the QRS complex, which of the following best describes an S-wave? Your answer: Any downward deflection following an R-wave. 7.
