Heart Pathology Chapter 11

Arrhythmia Any abnormal rhythm of the heart Atrioventricular-impulses are not through the Av node to the bundle of His –Causes the ventricles to contract slower than the atria Flutter- rapid contractions of the atria or ventricles Fibrillation- rapid random contractions

Congenital Heart Disease Any abnormalities present at birth –Coarctation of the Aorta (CoA)- constriction of the aorta –Patent Ductus (PDA)-a duct between the aorta and pulmonary artery –Septal Defects- hole in the septum between the ventricles

Tetralogy of Fallot- four defects together Pulmonary artery stenosis Ventricular septal defect Aorta shift to the right Hypertrophy of the right ventricle- smaller than it should be

Congestive Heart Failure Blood accumulates in the lungs- left side failure pulmonary edema Caused by hypertension and coronary heart disease Treatments- –ACE and beta-blockers –Left Ventricular assist device (LVAD)

Coronary Artery Disease CAD Atherosclerosis- fatty deposits in heart artries
