Ch. 5 Diagnositic Terms Flashcards
arrhythmia, disrhythmia
irregularity or loss of rhythm in a heartbeat
acute coronary syndrome (ACS)
signs and symptoms that indicate an active process of the pathological events leading to myocardial infarction
bradycardia
slow heart rate (<60 bpm)
fibrillation
chaotic, irregular contractions of the heart (atrial or ventricular)
premature ventricular contraction (PVC)
ventricular contraction preceding the normal impulse initiated by the SA node
tachycardia
fast heart rate (>100 bpm)
bacterial endocarditis
a bacterial infection that affects the endocardium or heart valves
cardiac tamponade
general term for disease of the heart muscle
congenital anomaly of the heart
malformations of the heart present at birth (congenital = born with, anomaly = irregularity)
atrial septal defect (ASD)
an opening in the interatrial septum
coarctation of the aorta
narrowing of the descending aorta, resulting in limited blood flow to the lower body
patent ductus arteriosus (PDA)
an abnormal opening between the pulmonary artery and the aorta (patent = opening)
ventricular septal defect (VSD)
an opening in the interventricular septum
congestive heart failure (CHF); left ventricular failure
failure of the left ventricle to pump an adequate amount of blood to the body, causing a “bottleneck” of congestion in the lungs and possible edema in the lower body
cor pumonale; right ventricular failure
enlargement of the right ventricle, resulting from chronic disease of the lungs, which causes congestion of the pulmonary circulation to the lungs (cor = heart)
