Write the differences between:
P-wave and T-wave
Solution
| 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. |
