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 depolarisation. During this phase, the ventricles relax and return to their normal state.
3 It is of atrial origin. It is of ventricular origin.
