A) R-repolarisation of ventricles
B) S-start of systole
C) T-end of diastole
D) P-depolarisation of the atria
Correct Answer: C
Solution :
| [C] In ECG, P-wave indicates impulse of contraction generated by SA-node and it spreads in atria causing atrial depolarisation. T-wave is the most constant and conspicuous wave having the tallest amplitude. It. is the first positive deflection during ventricular depolarisation. S-wave is the next downward deflection constant but often inconspicuous. T-wave is repolarisation wave of ventricular relaxation. |
