For effective EKG interpretation, one must first interpret its various components, which will be discussed in this short but concise EKG course. Atrial depolarization: the P-wave. In a normal heart an action potential generated in the SA-node will lead to depolarization of the atrial syncytium. The electrical activity associated with the depolarization of the atrial syncytium is visualized as a smooth complex on the ECG and is called the P wave. Normally, the P wave is an upright or positively deflected ECG complex. The PQ or PR interval. Once a cardiac impulse from the atria reaches the AV-node its speed of conduction is delayed. At this time no electrical activity is visible on the ECG.
