Definitions:

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.

Standard Leads

Predetermined positions on the body where electrodes are placed for the purpose of recording an electrocardiogram (ECG).

Lab Exercise

A practical, hands-on activity or experiment carried out in a laboratory setting for educational purposes, often to explore scientific principles.
