EKG wave that accompanies ventricular contraction (depolarization)

• P wave

• T wave

• QRS complex

• U wave

What the T wave on an EKG represents

• Atrial depolarization

• Ventricular depolarization

• Ventricular repolarization

• Atrial repolarization

Stage of a heartbeat where the ventricles contract and pump blood

• Diastole

• Systole

• Arrhythmia

• Cardiac Cycle

Factors that influence heart rate

• Body temperature

• Dietary habits

• Sleep duration

• Hydration levels

Vessels returning blood to the right atrium

• Pulmonary veins

• Coronary arteries

• Superior vena cava and inferior vena cava

• Aorta

Blood vessel generally used to determine blood pressure with a sphygmomanometer

• Brachial artery

• Femoral artery

• Radial artery

• Carotid artery

Natural pacemaker of the heart

• AV node

• SA node

• Bundle of His

• Purkinje fibers

Layers of a blood vessel in order from innermost to outermost layer
