.

Ventricular Recovery ventricular repolarization

.

.

.

atrial and ventricular beats per minute

.

.

.

Atrial and ventricular regular or irregular

.

.

.

The QRS occurs at regular intervals

.

.

.

Patterned irregularity eg, every third beat is early

.

.

.

Random irregularity without a pattern

.

.

.

A disturbance in the conduction system of the heart

.

.

.

low-pressure system sends blood to lungs

.

.

.

High pressure sends blood out to the body

.

.

.

contraction serves to empty the chambers, pump blood out

.

.

.

relaxation "filling time" serves to fill the chambers with blood

innermost layer (inside) must be smooth

.

muscular layer (thick)

.

.

.

outer layer/surface on the muscle surface

.

.

.

outermost layer, thick and fibrous job is to protect the heart

.

.

.

Supplies blood to Right Ventricle
