Question

In a standard ECG, which one of the following aiphabets is the correct representation of the respective activity of the human heart ?

Options

A.R- repolarisation of ventricles
B.S-start of systole
C.T-end of diastole
D.P-depolarisation of the atria

Solution

In ECG, P-wave indicates impulse of contraction generated by SA-node and it spreads in atria causibg atria 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-waver is repolarisation wave of ventricular relexation.
