Body Fluids and Circulation
Distinguish between P-wave and 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.|
