In a standard ECG, which one of the following alphabets is the correct representation of the respective activity of the human heart?
R-repolarisation of ventricles
S- start of systole
T -end of diastole
P- depolarization of the atria
D.
P- depolarization of the atria
In ECG, P-wave indicates impulse of contraction generated by SA-node and it spreads in atria causing atrial depolarization.
T-wave is the most constant and conspicuous wave having the tallest amplitude. It is the first positive deflection during ventricular depolarization.
S - wave is the next downward deflection constant but often inconspicuous.
T- wave is repolarisation wave of ventricular relaxation.
