20.
When performing an ECG, the P wave of the ECG complex represents the :__________
Correct Answer
atrial depolarization
Explanation
The P wave of the ECG complex represents atrial depolarization. Depolarization refers to the electrical activation of the heart muscle cells, causing them to contract. The P wave specifically represents the depolarization of the atria, which are the upper chambers of the heart. This electrical signal starts in the sinoatrial (SA) node, spreads through the atria, and leads to the contraction of the atrial muscles, which helps in filling the ventricles with blood. Therefore, the P wave on an ECG is a reflection of the electrical activity in the atria during the cardiac cycle.
