Med Term: Ch 7 Diagnostic Terms Part 1

Front 1

arrhythmia, dysrhythmia

Back 1

general irregularity or loss of rhythm of the heartbeat

Front 2

bradycardia

Back 2

slow heart rate (<60 beats/min)

Front 3

fibrillation

Back 3

chaotic, irregular contractions of the heart, as in atrial or ventricular fibrillation

Front 4

flutter

Back 4

extremely rapid but regular contractions of the heart, as in atrial or ventricular flutter (typicall from 250 to 350 beats/min)

Front 5

heart block

Back 5

an interference with the normal electrical conduction of the heart defined by the location of the block (i.e. AV block)

Front 6

premature ventricular contraction (PVS)

Back 6

ventricular contraction preceing the normal impulse initiated by the SA node (pacemaker)

Front 7

tachycardia

Back 7

fast heart rate (>100 beats/min)

Front 8

arteriosclerotic heart disease (ASHD)

Back 8

Degenerative condition of arteries: thickening of inner lining, loss of elasticity, and likely to rupture: seen in aged and smokers

Front 9

bacterial endocarditus

Back 9

bacterial inflammation that affects endocardium or heart valves

Front 10

cardiac tamponade

Back 10

compression of heart produced by the accumulation of fluid in pericardial sac. Results from pericarditis or trauma, causing rupture of a blood vessel in the heart (tampon = a plug)

Front 11

cardiomyopathy

Back 11

general term for disease of the heat muscle

Front 12

congenital anomaly of the heart

Back 12

malformations of the heart present at birth (anomaly = irregularity)

Front 13

atrial septal defect (ASD)

Back 13

an opening in the septum separating the atria

Front 14

coarctation of the aorta

Back 14

narrowing of the descending portion of the aorta resulting in a limited flow of blood to the lower part of the body

Front 15

patent ductus arteriosus (PDA)

Back 15

abnormal opening between the pulmonary artery and the aorta caused by the failure of the fetal ductus arteriosus to close after birth (patent = open)
