Cardiac Defects: Increased Pulmonary Blood Flow

An abnormal connection between the great arteries allows blood to flow from the right side of the heart to the left side.

Blood flows from the low-pressure right side of the heart to the high-pressure left side.

Intracardiac communication along the septum allows blood to flow from the low-pressure right side to the high-pressure left side. (correct)

An atrial septal defect causes blood to flow from the left side of the heart to the right side.

Elevated oxygen saturation levels

Hypertension

Increased peripheral pulses

Signs and symptoms of decreased cardiac output (correct)

Absent murmur

Diastolic murmur

Systolic murmur

Continuous machinery-like murmur (correct)
