Cardiovascular Physiology and EKG Analysis

Vocabulary flashcards covering key cardiovascular concepts including blood pressure dynamics, vascular tone, and EKG wave representations.

Systole

Blood pressure measured when the left ventricle contracts.

Diastole

Blood pressure measured when the left ventricle relaxes.

Vasodilation

The widening of blood vessels, which causes blood pressure to decrease.

Vasoconstriction

The narrowing of blood vessels, which causes blood pressure to increase.

Heart Rate (HR) and Blood Pressure Relationship

An increase in heart rate results in an increase in blood pressure.

P Wave

atrial depolarization.

QRS Complex

ventricular depolarization.

T Wave

ventricular repolarization.

Atrial Depolarization

The electrical activation of the atria that causes the atrium to contract.

Ventricular Depolarization

The electrical activation of the ventricles that causes the ventricles to contract.

Ventricular Repolarization

The electrical recovery of the ventricles during which the ventricles relax.
