Question

Write the differences between:

P-wave and T-wave

Answer 1

	P - wave	T - wave
1.	In an electrocardiogram (ECG), the P-wave indicates the activation of the SA node.	In an electrocardiogram (ECG), the T-wave represents ventricular relaxation.
2.	During this phase, the impulse of contraction is generated by the SA node, causing atrial depolarization.	During this phase, the ventricles relax and return to their normal state.
3.	It is of atrial origin.	It is of ventricular origin
