Web30 de mar. de 2024 · Hence, The correct answer is option (C). Note: In ECG, deflection is referred as wave only if it passes through the baseline, any negative waves at first represent the Q wave, if not one can consider the Q wave is absent and any positive wave represent the positive wave and any negative wave after the positive wave is S wave. Webrepresented by a positive deflection with a large, upright R in leads I, II, V4 - V6 and a negative deflection with a large, deep S in aVR, V1 and V2 in general, proceeding from V1 to V6, the R waves get taller while the S …

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. http://dspace.univer.kharkov.ua/bitstream/123456789/14418/2/Lecture_ECG_basics_2024-2024_1.pdf
