Definitions:

Heart Valves

Structures within the heart that open and close to control the flow of blood between its chambers and into the arteries.

ECG Pattern

The visual representation of the electrical activity of the heart as recorded by an electrocardiogram.

P Wave

A deflection in the ECG representing the electrical activity of atrial depolarization, preceding the contraction of the atria.

P-Q Segment

The portion of an electrocardiogram (ECG) trace between the end of the P wave and the start of the QRS complex, indicative of the time electrical impulse travels from the atria to the ventricles.
