Final answer:
A normal electrocardiogram (ECG or EKG) consists of five prominent points on the tracing: the P wave, QRS complex, and T wave. These points represent important electrical events in the heart.
Step-by-step explanation:
A normal electrocardiogram (ECG or EKG) consists of a tracing of five prominent points, which are abbreviated as:
- P wave: Represents the depolarization of the atria.
- QRS complex: Represents the depolarization of the ventricles.
- T wave: Represents the repolarization of the ventricles.
These points on the ECG tracing correspond to important electrical events in the heart.
